Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Business and Basis of Presentation | Business and Basis of Presentation Description of the Business Warrior Met Coal, LLC (the “Company” or, for the periods beginning as of April 1, 2016, the “Successor”) was formed on September 3, 2015 by certain Walter Energy, Inc. (“Walter Energy” or the “Parent”) lenders under the 2011 Credit Agreement, dated as of April 1, 2011 (the “2011 Credit Agreement”) and the noteholders under the 9.50% Senior Secured Notes due 2019 (such lenders and noteholders, collectively, “Walter Energy’s First Lien Lenders”) in connection with the acquisition by the Company of certain core operating assets of Walter Energy under section 363 under Chapter 11 of Title 11 (the "Chapter 11 Cases") of the U.S. Bankruptcy Code (“U.S. Bankruptcy Code”) in the Northern District of Alabama, Southern Division (the "Bankruptcy Court"). These operating assets acquired and liabilities assumed are referred to as the “Predecessor” for all periods on or before March 31, 2016. The Company and its Predecessor are a U.S. based producer and exporter of metallurgical (“met”) coal for a diversified customer base of blast furnace steel producers located primarily in Europe and South America. The Company also generates ancillary revenues from the sale of natural gas extracted as a byproduct from the underground coal mines and royalty revenues from leased properties. On November 5, 2015, Walter Energy and certain of its wholly owned U.S. subsidiaries (collectively, the "Walter Energy Debtors") entered into an asset purchase agreement (as amended, the “Asset Purchase Agreement”) with the Company, pursuant to which, among other things, the Company, on behalf of Walter Energy’s First Lien Lenders, agreed to acquire the Predecessor through a credit bid of $ 1.1 billion and a release of the liens under the 2011 Credit Agreement and the 9.50% Senior Secured Notes due 2019 (“Walter Energy First Lien Obligations”), to assume certain liabilities of the Walter Energy Debtors and to pay cash consideration in accordance with sections 363 and 365 of the U.S. Bankruptcy Code (the “Asset Acquisition”). On January 8, 2016, the Bankruptcy Court approved the Asset Acquisition, which closed on March 31, 2016. In connection with the Asset Acquisition, the Company also conducted rights offerings to Walter Energy’s First Lien Lenders and certain qualified unsecured creditors to purchase newly issued Class B Units of the Company, which diluted the Class A Units on a pro rata basis (the “Rights Offerings”). Proceeds from the Rights Offerings were used to pay certain costs associated with the Asset Acquisition and for general working capital purposes. Corporate Conversion and Initial Public Offering On April 12, 2017, in connection with the Company’s initial public offering (“IPO”), Warrior Met Coal, LLC filed a certificate of conversion, whereby Warrior Met Coal, LLC effected a corporate conversion from a Delaware limited liability company to a Delaware corporation and changed its name to Warrior Met Coal, Inc. In connection with this corporate conversion, the Company filed a certificate of incorporation. Pursuant to the Company’s certificate of incorporation, the Company is authorized to issue up to 140,000,000 shares of common stock $ 0.01 par value per share and 10,000,000 shares of preferred stock $ 0.01 par value per share. All references in the financial statements to the number of shares and per share amounts of common stock have been retroactively recast to reflect the corporate conversion. On April 19, 2017, the Company completed its IPO, whereby the selling stockholders named in the Registration Statement on Form S-1 (File No. 333-216499) sold 16,666,667 shares of common stock at a price to the public of $ 19.00 per share. The Company did not receive any proceeds from the sale of common stock in the IPO. All of the net proceeds from the IPO were received by the selling stockholders. The aggregate net proceeds to the selling stockholders in the IPO were $296.9 million , net of underwriting discounts and commissions of $19.8 million . The Company has paid cumulative offering expenses of $15.9 million on behalf of the selling stockholders. Upon the closing of the IPO, 53,442,532 shares of common stock were outstanding. Basis of Presentation Prior to the closing of the Asset Acquisition on March 31, 2016, the Company had no operations and nominal assets. The accompanying financial statements have been presented on a consolidated basis for the “Successor” periods subsequent to the Asset Acquisition, which include the year ended December 31, 2018 , the year ended December 31, 2017 , and the nine months ended December 31, 2016, and on a combined basis for the “Predecessor” periods prior to the Asset Acquisition, which includes the three months ended March 31, 2016. The financial information of the Company has been separated by a vertical line on the face of the financial statements to identify these different bases of accounting for Predecessor and Successor periods. Predecessor Presentation The Predecessor’s combined financial statements for the three months ended March 31, 2016 have been “carved-out” from the accounting records of Walter Energy. Historically, the Predecessor did not operate as an independent standalone company. For periods subsequent to filing the Chapter 11 Cases and prior to March 31, 2016, the Predecessor applied the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 852, Reorganizations, in preparing its combined financial statements. ASC 852 requires that the financial statements distinguish transactions and events that are directly associated with the reorganization from the ongoing operations of the business. Accordingly, certain revenues, expenses, realized gains and losses and provisions for losses that were realized or incurred in the Chapter 11 Cases have been recorded in a reorganization line item on the Combined Statements of Operations. Preparation of the combined financial statements, included making certain adjustments necessary to reflect all costs of doing business to present the historical records on a basis as if the Predecessor had been a separate standalone entity. These adjustments include, for example, allocations of Parent overhead and selling, general and administrative expenses. The historical costs and expenses reflected in the combined financial statements include an allocation for certain corporate functions historically provided by the Parent. Substantially all of the Predecessor’s senior management were employed by the Parent and certain functions critical to the Predecessor’s operations were centralized and managed by the Parent. Historically, the centralized functions included executive senior management, financial reporting, financial planning and analysis, accounting, shared services, information technology, tax, risk management, treasury, legal, human resources, and strategy and development. The costs of each of these services have been allocated to the Predecessor on the basis of the Predecessor’s relative headcount, revenue and total assets to that of the Parent. These cost allocations were $ 7.8 million for the three months ended March 31, 2016 (Predecessor). All intracompany transactions have been eliminated. The net effect of the settlement of transactions between the Predecessor, the Parent and other affiliates of the Parent, together with cash transfers to and from the Parent’s cash management accounts are reflected in the Statements of Changes in Stockholders' Equity and Parent Net Investment as net transfers to Parent and in the Statements of Cash Flows as a financing activity. The allocation methodologies have been described in these notes to the financial statements where appropriate, and management considers the allocations to be reasonable. The financial information included herein may not necessarily reflect the financial position, results of operations and cash flows of the Predecessor in the future or what they would have been had the Predecessor been a separate, standalone entity during the periods presented. The Parent used a centralized approach to cash management and financing of its operations. Historically, the majority of the Predecessor’s cash was transferred to the Parent on a daily basis. This arrangement is not reflective of the manner in which the Predecessor would have been able to finance its operations had it been a standalone business separate from the Parent during the periods presented. The Predecessor’s employees participated in benefit and stock-based compensation plans of the Parent. A portion of the cost of those plans is included in the combined financial statements. See Notes 14 and 15 for a further description of the accounting for benefit plans and stock-based compensation, respectively. The financial statements prior to April 1, 2016 included an allocation of a portion of debt and related interest expense from the Parent. Interest expense on the Parent’s debt attributed to the Predecessor was $16.6 million for the three months ended March 31, 2016 (Predecessor). |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Use of Estimates The Company prepares its financial statements in conformity with GAAP, which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the periods presented. Due to the inherent uncertainty involved in making estimates, actual results could differ from those estimates. Concentrations of Credit Risk and Major Customers The Company’s principal line of business is mining and marketing met coal to foreign steel producers. For the year ended December 31, 2018 , approximately 97.4% of sales were derived from coal shipments to customers, located primarily in Europe, South America and Asia. At December 31, 2018 approximately 95.6% of trade receivables related to these customers. For the year ended December 31, 2018 , our geographic customer mix was 55% in Europe, 31% in South America and 14% in Asia. The Company also generates ancillary revenues from the sale of natural gas extracted as a byproduct from the underground coal mines and royalty revenues from leased properties. During the year ended December 31, 2018 Xcoal Energy & Resources, Exiros BV Sucursal Uruguay and Huettenwerke Krupp Mannesmann GmbH accounted for $203.6 million , or 15.1% , $148.5 million , or 11.0% , and $141.3 million , or 10.5% of total revenues, respectively. During the year ended December 31, 2017 , Xcoal Energy & Resources and Salzgitter Flachstahl GmBH accounted for $181.9 million , or 16.1% , and $112.8 million , or 10% , of total revenues, respectively. During the nine months ended December 31, 2016, Salzgitter Flachstahl GmBH, Voestelpine and Huettenwerke Krupp Mannesmann GmBH accounted for $43.1 million , or 15.6% , $35.3 million , or 12.7% , and $34.0 million , or 12.3% of total revenues, respectively. During the three months ended March 31, 2016, Xcoal Energy & Resources and Voestelpine accounted for $10.7 million , or 16.4% and $8.3 million, or 12.8% of total revenues, respectively. Credit is extended based on an evaluation of the individual customer’s financial condition. In some instances, the Company requires letters of credit, cash collateral or prepayments from its customers on or before shipment to mitigate the risk of loss. These efforts have consistently resulted in minimal historical credit losses. Revenue Recognition The Company adopted Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers”, as of January 1, 2018, using the modified retrospective approach. The Company applied the standard to all customer contracts entered into as of the date of initial application. The Company concluded that the adoption did not change the timing at which the Company historically recognized revenue nor did it have a material impact on its consolidated financial statements. For periods prior to January 1, 2018, revenue was recognized when the following criteria had been met: (i) persuasive evidence of an arrangement existed; (ii) the price to the buyer was fixed or determinable; (iii) delivery had occurred; and (iv) collectability was reasonably assured. Delivery is considered to have occurred at the time title and risk of loss transfers to the customer. For coal shipments to domestic customers via rail, delivery occurs when the railcar is loaded. For coal shipments to international customers via ocean vessel, delivery occurs when the vessel is loaded at the Port of Mobile, Alabama. For natural gas sales, delivery occurs when the gas has been transferred to the pipeline. For periods subsequent to January 1, 2018, revenue is recognized when performance obligations under the terms of a contract with our customers are satisfied; for all contracts this occurs when control of the promised goods have been transferred to our customers. For coal shipments to domestic customers via rail, control is transferred when the railcar is loaded. For coal shipments to international customers via ocean vessel, control is transferred when the vessel is loaded at the Port of Mobile, Alabama. For natural gas sales, control is transferred when the gas has been transferred to the pipeline. Revenue is disaggregated between coal sales within the Company's mining segment and natural gas sales included in all other revenues, as disclosed in Note 23. Our coal and gas sales generally include up to 45-day payment terms following the transfer of control of the goods to the customer. We typically do not include extended payment terms in our contracts with customers. Shipping and Handling Costs incurred to transport coal to the point of sale at the Port of Mobile, Alabama, are included in cost of sales and the gross amounts billed to customers, if any, to cover shipping and handling to the ultimate/final destination are included in sales. Cash and Cash Equivalents and Restricted Cash The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the Balance Sheets that sum to the total of the same such amounts shown in the Statements of Cash Flows (in thousands): Successor December 31, 2018 December 31, 2017 Cash and cash equivalents $ 205,577 $ 35,470 Restricted cash included in other long-term assets 828 794 Total cash and cash equivalents and restricted cash included in the Statements of Cash Flows $ 206,405 $ 36,264 Cash and cash equivalents include short-term deposits and highly liquid investments that have original maturities of three months or less when purchased and are stated at cost, which approximates fair value. As of December 31, 2018 and December 31, 2017 , restricted cash included in other long-term assets in the Balance Sheet represents amounts invested in certificate of deposits as financial assurance for post mining reclamation obligations. Short-Term Investments Instruments with maturities greater than three months, but less than twelve months, are included in short-term investments. The Company purchases United States Treasury bills with maturities ranging from six to twelve months which are classified as held to maturity and are carried at amortized cost, which approximates fair value. Securities classified as held to maturity securities are those securities that management has the intent and ability to hold to maturity. As of December 31, 2018 and December 31, 2017 , the Company’s short-term investments consisted of $17.5 million in Treasury bills with a maturity of six months . These Treasury bills were posted as collateral for the self-insured black lung related claims asserted by or on behalf of former employees of Walter Energy and its subsidiaries, which were assumed in the Asset Acquisition and relate to periods prior to March 31, 2016. Inventories Inventories are valued at the lower of cost or net realizable value. Coal inventory costs include labor, supplies, equipment costs, operating overhead, freight, royalties, depreciation and depletion and other related costs. Coal inventories are valued using the first-in, first-out (“FIFO”) inventory valuation method. The valuation of coal inventories is subject to estimates due to possible gains and losses resulting from inventory movements from the mine site to storage facilities, inherent inaccuracies in belt scales and aerial surveys used to measure quantities and fluctuations in moisture content. Periodic adjustments to coal tonnages on hand are made for an estimate of coal shortages and overages due to these inherent gains and losses, primarily based on historical results from aerial surveys and periodic coal pile clean-ups. Supplies inventories are valued using the average cost method of accounting. Management evaluates its supplies inventory in terms of excess and obsolete exposures which includes such factors as anticipated usage, inventory turnover, inventory levels and ultimate market value. A reserve for excess and obsolete supplies inventory is established and charged to cost of sales in the Statements of Operations. Deferred Longwall Move Expenses Direct costs, including labor and supplies, associated with moving longwall equipment and the related equipment refurbishment costs are deferred and included in prepaid expenses. These deferred costs are amortized on a unit-of-production basis into cost of sales over the life of the subsequent panel of coal mined by the longwall equipment. See Note 5 for further disclosures related to deferred longwall move expenses. Advanced Mining Royalties Lease rights to coal reserves are often acquired in exchange for royalty payments. Advance mining royalties are advance payments made to lessors under terms of mineral lease agreements that are recoupable against future production royalties. These advance payments are deferred and charged to operations as the coal reserves are mined. Advance mining royalties are included in other long-term assets. Property, Plant and Equipment Property, Plant and Equipment Property, plant and equipment are recorded at cost. Depreciation is recorded principally on the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized on the straight-line method over the lesser of the useful life of the improvement or the remaining lease term. Estimated useful lives used in computing depreciation expense range from three to ten years for machinery and equipment, and from fifteen to thirty years for land improvements and buildings. Well life is used to estimate the useful life for gas properties and related development, and mine life is used for amortizing mine development costs. Gains and losses upon disposition are reflected in the Statements of Operations in the period of disposition. Maintenance and repair expenditures are charged to cost of sales as incurred. Deferred Mine Development Costs of developing new underground mines and certain underground expansion projects are capitalized. Underground development costs, which are costs incurred to make the coal physically accessible, may include construction permits and licenses, mine design, construction of access roads, main entries, airshafts, roof protection and other facilities. Mine development costs are amortized primarily on a unit-of-production basis over the estimated reserve tons directly benefiting from the capital expenditures. Costs amortized during the production phase of a mine are capitalized into inventory and expensed to cost of sales as the coal is sold. Owned and Leased Mineral Interests Costs to obtain coal reserves and lease mineral rights are capitalized based on cost or the fair value at acquisition and depleted using the unit-of-production method over the life of proven and probable reserves. Lease agreements are generally long-term in nature (original terms range from 10 to 50 years) and substantially all of the leases contain provisions that allow for automatic extension of the lease term provided certain requirements are met. Depletion expense was $9.6 million , $ 9.4 million , and $4.5 million for the years ended December 31, 2018 and December 31, 2017 , and the nine months ended December 31, 2016 , respectively, and is included in depreciation and depletion in the accompanying Statements of Operations. There was no depletion expense recorded for the three months ended March 31, 2016 (Predecessor). Asset Retirement Obligations The Company has certain asset retirement obligations primarily related to mine closing reclamation costs, perpetual water care costs and other costs associated with dismantling and removing facilities. Asset retirement obligations are determined for each mine using various estimates and assumptions, including estimates of disturbed acreage as determined from engineering data, estimates of future costs to reclaim the disturbed acreage and the timing of related cash flows, discounted using a credit-adjusted, risk-free rate. The Company's asset retirement obligations also include estimates to reclaim gas well in accordance with the Oil and Gas Board of Alabama. On at least an annual basis, the Company reviews the entire asset retirement obligation liability and makes necessary adjustments for permit changes, the anticipated timing of mine closures, and revisions to cost estimates and productivity assumptions to reflect current experience. As changes in estimates occur, the carrying amount of the obligation and asset are revised to reflect the new estimate after applying the appropriate credit-adjusted, risk-free discount rate. The future costs of these obligations are accrued at the estimated fair value in the period in which it is incurred if a reasonable estimate of fair value can be made. The present value of the estimated asset retirement cost is capitalized as part of the carrying amount of the long-lived asset. For sites where there is no asset, expense or income is recognized for changes in estimates. Capitalized asset retirement costs are amortized on a unit-of-production basis over the estimated reserves. Accretion of the asset retirement obligation is recognized over time and generally will escalate over the life of the producing asset, typically as production declines. Accretion is included in cost of sales on the Statements of Operations. Accrued mine closing costs, perpetual care costs and reclamation costs and other costs of dismantling and removing facilities are regularly reviewed by management and revised for changes in future estimated costs and regulatory requirements, as necessary. For ongoing operations, adjustments to the liability result in an adjustment to the corresponding asset. For some operations, adjustments to the liability are recognized as income or expense in the period the adjustment is recorded as no asset was recorded to offset the liability established during purchase accounting as the operations were idle at that time. Any difference between the recorded obligation and the actual cost of reclamation is recorded in profit or loss in the period the obligation is settled. See Note 9 for further disclosures related to asset retirement obligations. Impairment of Long-Lived Assets Property, plant and equipment and other long-lived assets are reviewed for impairment at least annually or whenever events or changes in circumstances indicate that the book value of the asset may not be recoverable. The Company periodically evaluates whether events and circumstances have occurred that would indicate possible impairment. When impairment indicators exist, the Company uses an estimate of the future undiscounted cash flows of the related asset or asset group over the remaining life in measuring whether or not the asset values are recoverable. If the carrying amount of an asset or asset group exceeds its estimated future cash flows, impairment is recognized equal to the amount by which the carrying amount of the asset exceeds the fair value of the asset or asset group. Fair value is generally determined using market quotes, if available, or a discounted cash flow approach. The Company’s estimate of future undiscounted cash flows is based on assumptions including long-term met coal pricing forecasts, anticipated production volumes and mine operating costs for the life of the mine or estimated useful life of the asset. Equity Award Compensation (Successor) The Company accounts for equity award-based compensation to employees and non-employee/directors in accordance with ASC 718 requiring employee equity awards to be accounted for under the fair value method adjusted for estimated forfeitures rates based on historical experience. The Company recognizes compensation expense associated with equity awards for all awards made to employees as the requisite service, performance and market vesting conditions are met. The Company measures compensation expense based on the grant-date fair value of the awards calculated using a Black-Scholes or Monte Carlo valuation model. Compensation expense for equity awards with a service-only condition is recognized over the employee’s requisite service period using a graded vesting method. For awards with a performance condition that affects vesting, the performance condition is not considered in determining the award’s grant-date fair value; however, the performance conditions are considered when estimating the quantity of awards that are expected to vest. No compensation expense is recorded for awards with performance conditions until the performance condition is determined to be probable of achievement. For awards with a market condition that affects vesting, the market condition is considered in determining the award’s grant-date fair value. Compensation expense for awards with a market condition is recognized straight-line over the derived or implied service period. For awards with both performance and market conditions, the market condition is incorporated into the fair value of the award, while the performance condition impacts the timing of expense recognition. Compensation expense for equity awards is included in cost of sales (exclusive of items shown separately below) and selling, general and administrative in the accompanying Statements of Operations. Stock-Based Compensation (Predecessor) Prior to the Asset Acquisition, the Parent periodically granted stock-based awards to its employees and its board of directors. Stock-based compensation expenses related to these awards were allocated to the Predecessor based on the awards and terms previously granted to the employees of the Predecessor’s business units or subsidiaries as well as an allocation of the Parent’s corporate employee expenses. The Parent measured stock options and other stock-based awards granted to employees and directors based on the fair value on the date of the grant and recognized compensation expense for those awards, net of estimated forfeitures, over the requisite service period, which was generally the vesting period of the respective award. The Parent recognized compensation expense for only the portion of awards that were expected to vest. In developing a forfeiture rate estimate, the Parent considered its historical experience to estimate pre-vesting forfeitures for service-based awards. The impact of a forfeiture rate adjustment was recognized in full in the period of adjustment, and when the actual forfeiture rate was materially different from the estimate. The Parent used the Black-Scholes option pricing model to value stock option grants and also estimated forfeitures in calculating the expense related to stock-based compensation. The Parent used the Monte Carlo simulation to value its performance share units in calculating the expense related to stock-based compensation. Deferred Financing Costs The costs to obtain new debt financing or amend existing financing agreements are deferred and amortized to interest expense over the life of the related indebtedness or credit facility using the straight line method. As of December 31, 2018 and December 31, 2017 , respectively, there were $ 3.1 million and $ 2.2 million , respectively, of origination fees related to the ABL Facility (as defined below) in other long-term assets on the accompanying Balance Sheet. As of December 31, 2018 and December 31, 2017 there were $6.8 million and $ 7.8 million , respectively of unamortized deferred financing costs and debt discount, net, related to the Notes (as defined below), which is presented as a net deduction from the carrying amount of the debt recognized in the accompanying Balance Sheet. Income Taxes The Company records a tax provision for the expected tax effects of the reported results of operations. The provision for income taxes is determined using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax impact of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carryforwards. Deferred income tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets and liabilities are expected to be realized or settled. The Company records a valuation allowance to reduce deferred income tax assets to the amount that is believed more likely than not to be realized. When the Company concludes that all or part of the net deferred income tax assets are not realizable in the future, the Company makes an adjustment to the valuation allowance that is charged to earnings in the period that such determination was made. The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Results of operations of the Predecessor were historically included in the consolidated federal and state income tax returns of the Parent. The income tax provision included in the Predecessor financial statements was calculated using a method consistent with a separate return basis, as if the Predecessor’s business had been a separate taxpayer. Similarly, historical tax attributes (net operating losses, alternative minimum tax credits, etc.) were allocated to the Predecessor’s business utilizing a reasonable method of allocation. Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three level hierarchy has been established for valuing assets and liabilities based on how transparent (observable) the inputs are that are used to determine fair value, with the inputs considered most observable categorized as Level 1 and those that are the least observable categorized as Level 3. Hierarchy levels are defined as follows: Level 1: Quoted prices in active markets for identical assets and liabilities. Level 2: Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data. Level 3: Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques. New Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-02, "Leases (Topic 842)". ASU 2016-02 contains accounting guidance that will require a lessee to recognize a right of use asset and lease liability on the balance sheet for all leases, with the exception of short-term leases. Additional qualitative disclosures along with specific quantitative disclosures will also be required. The Company adopted this standard on January 1, 2019 using the modified retrospective approach. The Company has concluded that the adoption of this standard did not have a material impact on the Company's consolidated financial position and results of operations. In August 2017, the FASB issued ASU 2017-12, “Targeted Improvements to Accounting for Hedging Activities.” The new guidance provides targeted improvements to the accounting for hedging activities to better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedging results. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years; early adoption is permitted. The Company is currently in the process of evaluating the standard. |

Business Combinations [Abstract] | |
Acquisition of the Predecessor | Acquisition of the Predecessor On November 5, 2015, the Walter Energy Debtors entered into the Asset Purchase Agreement with the Company, pursuant to which, among other things, the Company, on behalf of Walter Energy’s First Lien Lenders, agreed to acquire the Predecessor via a credit bid and release of the liens on the Walter Energy First Lien Obligations. On January 8, 2016, the Bankruptcy Court approved the Asset Acquisition, which closed on March 31, 2016. The cash consideration of $ 50.8 million included the funding of escrow accounts to be used to pay certain expenses on behalf of the Walter Energy Debtors, some of which required residual amounts contained in the escrow accounts to be refunded to the Company after a specified time period. The Company received refunds of approximately $9.4 million during the nine months ended December 31, 2016, which is presented in the investing section of the Statement of Cash Flows. The net cash paid for the Asset Acquisition was $ 24.1 million , which was $ 50.8 million of cash paid less cash and cash equivalents acquired of $ 26.7 million . The purchase consideration has been allocated to the assets acquired and liabilities assumed based upon their estimated fair values at the date of the Asset Acquisition. During the first quarter of 2017, the Company completed the valuation of the assets and liabilities with the assistance of an independent third party and recorded a measurement-period adjustment to the preliminary purchase price allocation. The measurement-period adjustment was due to updated estimates for the acquired mineral interests including estimates for future royalty income, production volumes and timing which resulted in a $3.5 million decrease in fair value allocated to mineral interests as compared to the December 31, 2016 preliminary fair value. This also resulted in a decrease to additional paid in capital. The measurement-period adjustment was recorded during the first quarter of 2017 and had no impact on reported earnings for the years ended December 31, 2018 and 2017, respectively. In determining the fair values of net assets acquired in the Asset Acquisition, the Company considered, among other factors, the analyses of the Predecessor’s historical financial performance and estimates of the future performance of the acquired business, as well as the highest and best use of the acquired assets. Working capital, excluding inventory, and non-current restricted cash were recorded at the Predecessor’s carrying value, which is representative of the fair value on the date of acquisition. Inventory was valued at its net realizable value. Mineral interest was recorded at fair value utilizing the income approach. The income approach utilized the Company’s operating projections as of the valuation date. Under the income approach, fair value was estimated based upon the present value of future cash flows. A number of significant assumptions and estimates were involved in forecasting the future cash flows including sales volumes and prices, costs to produce (including costs for labor, commodity supplies and contractors), transportation costs, capital spending, working capital changes and a risk adjusted, after-tax cost of capital (all of which generally constitute unobservable Level 3 inputs under the fair value hierarchy). Property, plant and equipment, and other assets were recorded at fair values based on the cost and market approaches. The cost approach utilized trending and direct costing techniques to develop replacement costs. The market approach is based on independent secondary market data (which generally constitute Level 2 inputs under the fair value hierarchy). Black lung obligations and asset retirement obligations were recorded at fair value using a combination of market data, operational data and discounted cash flows and were adjusted by a discount rate factor reflecting current market conditions at the time of acquisition. The following tables summarize the final purchase price allocation, including the applicable measurement-period adjustments made upon finalization during the first quarter of 2017 (in thousands): Final purchase price: Cash paid $ 50,830 Fair value of First Lien Obligations relinquished in exchange for net assets of the Predecessor 598,607 Total purchase price $ 649,437 Final fair values of assets acquired and liabilities assumed: Cash and cash equivalents $ 26,723 Trade and other receivables 14,358 Inventories 46,464 Prepaid expenses and other current assets 30,722 Mineral interests 144,224 Property, plant and equipment 533,441 Other long-term assets 28,865 Total assets 824,797 Accounts payable 10,470 Accrued expenses 12,843 Other current liabilities 24,044 Current debt 2,879 Long-term debt 5,758 Deferred income taxes 1,400 Other long-term liabilities 117,966 Total liabilities 175,360 Total fair value of net assets acquired $ 649,437 Supplemental Unaudited Pro Forma Financial Information The following unaudited pro forma results of operations give effect to the Asset Acquisition as if it had occurred on January 1, 2015. This unaudited pro forma financial information should not be relied upon as necessarily being indicative of the historical results that would have been obtained if the Asset Acquisition had actually occurred on that date, nor the results of operations in the future. The supplemental unaudited pro forma financial information was adjusted to (i) reflect the impact of certain fair value adjustments, including an adjustment to depreciation and depletion expense as a result of a change in the basis of property, plant and equipment and mineral interests, (ii) eliminate historical interest expense related to the notes, loans and other debt that was not assumed by the Company as part of the Asset Acquisition, (iii) eliminate a gain on reorganization items associated with the Chapter 11 Cases and (iv) eliminate the Predecessor's historical other postretirement benefit expense associated with the Predecessor's historical other postretirement benefit obligations for retiree medical and life insurance benefits, which were not assumed by the Company. Successor For the year ended December 31, 2016 (in thousands) As (1) Pro forma (2) Revenue $ 297,634 $ 369,017 Net loss $ (49,673 ) $ (67,476 ) (1) Reflects nine months of Successor period operations.

The Tax Cuts and Jobs Act significantly revised the U.S. corporate income tax regime by, among other things, lowering the U.S. corporate tax rate from 35% to 21% effective January 1, 2018, while also repealing the deduction for domestic production activities, implementing a territorial tax system, limiting the deduction for interest expense, limiting the use of net operating losses generated on or after January 1, 2018 to offset taxable income and repealing the corporate alternative minimum tax ("AMT") and triggering refunds of prior year AMT credits. On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 ('SAB 118") to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act. The Company applied SAB 118 to recognize the provisional tax impacts related to the revaluation of deferred tax assets and liabilities and the impact of AMT tax credits in its consolidated financial statements for the year ended December 31, 2017. On January 14, 2019, the Internal Revenue Service ("IRS") issued a statement that AMT refunds for taxable years beginning after December 31, 2017 will not be subject to sequestration which reversed an earlier IRS announcement that refundable AMT credits would be subject to sequestration. As a result, in the fourth quarter of 2018, the Company completed its accounting for the income tax effects of the Tax Cuts and Jobs Act and recorded a measurement period adjustment recognizing an income tax receivable and related income tax benefit of $2.8 million . As of December 31, 2018, the Company has a current income tax receivable of $21.6 million and a non-current income tax receivable of $21.3 million of AMT credits, which are expected to be received in 2019 through 2022. Income Tax Expense (Benefit) Income tax expense (benefit) consisted of the following (in thousands): Successor Predecessor For the year ended For the year ended For the nine months ended For the three 2018 2017 2016 2016 Current Federal $ (2,776 ) $ (36,906 ) $ (526 ) $ — State — — — — (2,776 ) (36,906 ) (526 ) — Deferred Federal (176,141 ) (1,712 ) 542 16 State (46,897 ) 26 2 2 (223,038 ) (1,686 ) 544 18 Total $ (225,814 ) $ (38,592 ) $ 18 $ 18 Total income tax expense (benefit) differs from the expected tax expense (benefit) (computed by multiplying the U.S. federal statutory rate of 21% in 2018 and 35% in both 2017 and 2016 by income before income taxes) as a result of the following (in thousands): Successor Predecessor For the year ended For the year ended For the nine months ended For the three 2018 2017 2016 2016 Income (loss) before income tax expense (benefit) $ 470,973 $ 416,454 $ (49,655 ) $ (61,798 ) Tax expense (benefit) at statutory tax rate 98,904 145,759 (17,379 ) (21,629 ) Effect of: Depletion (18,227 ) (25,212 ) — — Estimate of the Tax Cuts and Jobs Act impact (2,775 ) (38,592 ) — — State and local income tax, net of federal effect 14,897 9,620 (1,051 ) (1,615 ) Valuation allowance on deferred tax assets (312,493 ) (129,245 ) 14,460 22,204 Non-deductible transaction costs 566 4,506 4,318 — Impact of restructuring — — — 1,111 Other (6,686 ) (5,428 ) (330 ) (53 ) Tax expense (benefit) recognized $ (225,814 ) $ (38,592 ) $ 18 $ 18 Deferred Taxes Deferred income tax assets and liabilities reflect the effects of tax losses, credits, and the future income tax effects of temporary differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates that apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Significant components of the Company's deferred income tax assets and liabilities were (in thousands): Successor December 31, 2018 December 31, 2017 Deferred income tax assets: Net operating loss and credit carryforwards $ 298,180 $ 395,526 Inventory 119 1,083 Asset retirement obligations 15,526 23,765 Black lung obligations 6,720 7,991 Accrued expenses 3,611 561 Other 2,767 197 Total 326,923 429,123 Less: valuation allowance for deferred income tax assets — (312,493 ) Net deferred income tax assets 326,923 116,630 Deferred income tax liabilities: Prepaid expenses (9,894 ) (9,416 ) Property, plant and equipment (92,361 ) (105,715 ) Other (1,888 ) (1,757 ) Total deferred income tax liabilities (104,143 ) (116,888 ) Net deferred income tax asset (liability) $ 222,780 $ (258 ) On March 31, 2016, the Company experienced an ownership change for purposes of Section 382 of the Internal Revenue Code of 1986, as amended (the "Code"). As a result of such ownership change, absent an applicable exception to such rules, an annual limitation under Section 382 would apply for federal and certain state income tax purposes with respect to the utilization of net operating loss carryforwards ("NOLs"). In 2017, the Company requested a private letter ruling ("PLR") from the Internal Revenue Service ("IRS") to clarify certain matters, that if ruled favorably on by the IRS, would allow the Company to qualify for an exception to the aforementioned rules limiting its utilization of its NOLs. On September 18, 2017, the IRS issued to the Company a favorable PLR. Prior to the issuance of the PLR, the Company operated and prepared its financial statements based on an assumption that an annual limitation on the utilization of the NOLs existed. As a result of qualifying for such exception, the Company's gross federal and state NOLs were revised downward to approximately $1.9 billion and $2.0 billion , respectively, as of December 31, 2016 and $1.6 billion for both federal and state NOLs as of December 31, 2017. This revision reflected a decrease to the NOL deferred tax asset and a corresponding adjustment to the valuation allowance recorded against those NOLs. If the Company were to undergo a subsequent ownership change our ability to utilize our NOLs and other tax attributes could be subject to severe limitations. The Company has federal net operating loss carryforwards of approximately $1.1 billion as of December 31, 2018, which expire predominantly in December 31, 2034 through December 31, 2036. The Company has state net operating loss carryforwards of approximately $1.2 billion , which expire predominantly in December 31, 2029 through December 31, 2031. In addition, the Company has approximately $11.5 million of general business credits which begin to expire in December 31, 2027 and fully expire in December 31, 2034. Valuation Allowance The Company periodically assesses whether it is more likely than not that it will generate sufficient taxable income to realize its deferred income tax assets. The Company establishes valuation allowances if it is not likely it will realize its deferred income tax assets. In making this determination, the Company considers all available positive and negative evidence and makes certain assumptions. The Company considers, among other things, all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, the overall business environment, its historical financial results, the industry's historically cyclical financial results, its cumulative three-year income or loss position and potential current and future tax planning strategies. The Company recorded a full valuation allowance in 2016 due to the Company being in a three-year cumulative loss position at that time, compounded by the negative industry-wide business trends and outlook. At December 31, 2017, the Company had a $312.5 million valuation allowance established against its deferred income tax assets, which represented a full valuation allowance against its net deferred income tax assets. For 2017, the Company recorded a pre-tax profit of $416.5 million ; however, the Company remained in a three-year cumulative loss position, had limited operating results as a new Company and given the industry's recent history of significant losses concluded as of December 31, 2017 that another year of significant profitability was needed to support a release of the valuation allowance. During 2018, the Company continued the trend of sustained profitability, recording a pre-tax profit of $471.0 million for the year. During the fourth quarter of 2018, after considering all relevant factors, the Company concluded that its deferred income tax assets are more likely than not to be realized. In evaluating the likelihood of utilizing its deferred tax assets, the significant relevant factors that the Company considered are: (1) its recent history of profitability; (2) growth in the U.S. and global economies; (3) estimates of future met coal prices; (4) the Company moved from a three-year cumulative loss position to a cumulative income position for the first time since it established the full valuation allowance; and (5) future impact of taxable temporary differences. Based on this evaluation, at December 31, 2018, the Company released its valuation allowance against its net deferred income tax assets resulting in a $225.8 million income tax benefit. The following table shows the balance of our valuation allowance and the associated activity: Successor December 31, 2018 December 31, 2017 Beginning balance $ 312,493 $ 767,290 Addition/(Reduction) - current tax expense/(benefit) (86,679 ) (129,245 ) Reduction due to application of IRC Section 382 — (130,327 ) Estimate of Tax Cuts and Jobs Act impact — (195,225 ) Release $ (225,814 ) $ — Ending balance $ — $ 312,493 Uncertain Tax Positions The Parent filed income tax returns in the U.S. and in various state and local jurisdictions which are routinely examined by tax authorities in these jurisdictions. Net operating losses and carryforwards are subject to adjustments based on examination and the statute of limitations is currently open for all such loss and credit carryforwards. The Company had no unrecognized tax benefits or accruals for unrecognized tax benefits as of December 31, 2018 and 2017, respectively. The Company did not record any interest or penalties associated with income taxes but would record interest and penalties within income tax expense. |

Asset Retirement Obligations | Asset Retirement Obligations Changes in the asset retirement obligations (“ARO”) were as follows (in thousands): Successor For the twelve months ended December 31, 2018 For the twelve months ended Balance at Beginning of Period $ 99,668 $ 99,148 ARO liability assumed in the Asset Acquisition — — Accretion expense 4,619 1,834 Revisions to estimates (42,064 ) (658 ) Obligations settled (399 ) (656 ) Balance at End of Period $ 61,824 $ 99,668 The portion of costs expected to be paid within a year of December 31, 2018 is $ 2.8 million . The portion of costs expected to be incurred beyond one year as of December 31, 2018 is $ 59.0 million . There were no assets that were legally restricted for purposes of settling asset retirement obligations at December 31, 2018 . Alabama's regulatory framework technically allows for self-bonding, as a practical matter, due to the onerous regulatory requirements for self-bonding, mining companies in Alabama utilize surety bonds, collateral bonds, or letters of credit to meet their financial assurance requirements. At December 31, 2018 , the Company had outstanding surety bonds and letters of credit with parties for post-mining reclamation at all of its mining operations totaling $44.4 million , and $2.1 million for miscellaneous purposes. Additionally, the Company had $0.8 million invested in certificate of deposits as financial assurance for post mining reclamation obligations. For the year ended December 31, 2018 and December 31, 2017 , the reduction to the liability was primarily attributable to the net impact of changes in discount rates, current estimates of the costs and scope of remaining reclamation work and fluctuations in projected mine life estimates. For the year ended December 31, 2018 , $24.6 million or $0.47 per share, of the adjustment to the liability was reflected as income in the period because there was no asset recorded to offset the adjustment to the liability. This portion of the liability relates to operations that were idle at the time of purchase accounting and no value was attributed to any asset as an offset for the asset retirement obligation. |

The restructuring charges consist primarily of severance and related benefits costs. The Company does not expect to incur any additional restructuring charges in the Successor periods in connection with the Predecessor restructuring actions. |

Self Insurance Reserve Disclosure [Abstract] | |
Pneumoconiosis (Black Lung) Obligations | Pneumoconiosis ("Black Lung") Obligations The Company is responsible for medical and disability benefits for black lung disease under the Federal Coal Mine Health and Safety Act of 1969, as amended. Beginning on April 1, 2016 through May 31, 2018, the Company was insured under a guaranteed cost insurance policy, through a third-party insurance carrier, for black lung claims raised by any employee subsequent to the Asset Acquisition. Beginning June 1, 2018, the Company has a deductible policy where the Company is responsible for the first $0.5 million for each black lung claim. In addition, in connection with the Asset Acquisition, the Company assumed all black lung liabilities of Walter Energy and its U.S. subsidiaries incurred prior to March 31, 2016. The Company is self-insured for the black lung claims assumed in the Asset Acquisition. Due to a limited operating history as a stand-alone company and as a result of being self-insured for these historical black lung claims, the Department of Labor required the Company to post $ 17.5 million in Treasury bills as collateral, in addition to maintaining a black lung trust acquired in the Asset Acquisition. The $ 17.5 million of collateral is recognized as short-term investments and the $ 3.6 million and $ 4.0 million black lung trust is offset against the long-term portion of the black lung obligations within the Balance Sheet as of December 31, 2018 and December 31, 2017, respectively. Under the terms of the agreement with the U.S. Department of Labor, the Company may elect to replace the $ 17.5 million collateral deposit with a surety bond or other form of assurance every six months. The estimated total black lung liabilities (net of black lung trust assets) were $ 26.8 million as of December 31, 2018 , of which $ 1.6 million is classified in other current liabilities and the remainder of $ 25.2 million is shown as a long-term liability in a separate line item in the Consolidated Balance Sheet. For the year ended December 31, 2017 , the estimated black lung liabilities were $ 31.9 million , of which $ 1.7 million is classified in other current liabilities and $ 30.2 million is displayed as a long-term liability in a separate line item in the Balance Sheet. The Company performs an annual evaluation of its black lung liabilities at each balance sheet date. The calculation uses assumptions regarding rates of successful claims, discount factors, benefit increases and mortality rates, among others. |

Retirement Benefits [Abstract] | |
Pension and Other Postretirement Benefits | Pension and Other Postretirement Benefits Successor Benefit Plans In connection with the Asset Acquisition, the Company did not assume any of the Parent’s obligations under the plans discussed in further detail below. The Company established new employee benefit plans for its employees subsequent to closing the Asset Acquisition. The plans are defined contribution plans. Contributions to these defined contribution plans amounted to $ 3.1 million for the year ended December 31, 2018 , $ 1.4 million for the year ended December 31, 2017 and $1.1 million for the nine months ended December 31, 2016. New Initial CBA In connection with the Asset Acquisition, the Company negotiated a new initial collective bargaining agreement (“CBA”) with the United Mine Workers of America ("UMWA") (the “UMWA CBA”), which was ratified by UMWA’s members on February 16, 2016 and expires on March 31, 2021. Pursuant to the UMWA CBA, the Company agreed to contribute $25.0 million to a Voluntary Employee Beneficiary Association (“VEBA”) trust formed and administered by the UMWA. Approximately 69% of the Company's employees were represented by the UMWA as of December 31, 2018 and December 31, 2017 . Predecessor Benefit Plans In the Predecessor periods, the Parent had various defined benefit pension plans covering eligible salaried and hourly employees. The Parent also provided certain postretirement benefits other than pensions, primarily healthcare, to eligible retirees. In addition to its own pension plans and other postretirement benefit plans, the Parent contributed to several multi-employer benefit plans covering eligible employees who were represented by the UMWA. The Parent funded its defined benefit pension plans in amounts sufficient to satisfy the “Minimum Funding Standards” of the Employee Retirement Income Security Act of 1974 (“ERISA”). Other postretirement benefit plans were funded as benefits were paid or as assessed by third-party plan sponsors. On December 28, 2015 the Bankruptcy Court entered the Memorandum Opinion and Order Granting Debtors’ Motion for an Order (I) authorizing the Walter Energy Debtors to (A) reject collective bargaining agreements, (B) implement final labor proposals, and (C) terminate retiree benefits; and (II) granting related relief, authorizing the Walter Energy Debtors to reject their collective bargaining agreements with the UMWA (the “UMWA Order”). The UMWA Order authorized the Walter Energy Debtors to reject their collective bargaining agreements with the UMWA and allow for the sale of the Walter Energy Debtors’ assets free and clear of collective bargaining obligations. The contributions to the Parent’s defined benefit plans related to the Predecessor’s employees recognized as expenses were $6.2 million for the three months ended March 31, 2016 (Predecessor). UMWA Multi-employer Benefit Plans The Parent was required under its agreement with the UMWA to contribute to multiemployer plans providing pension, healthcare and other postretirement benefits. At December 31, 2015, approximately 61.4% of the Predecessor’s workforce was represented by the UMWA and covered under the Predecessor’s collective bargaining agreement, which began July 11, 2012 and was to expire December 31, 2016. The Predecessor’s obligations to make contributions to the UMWA multi-employer pension and benefit plans ceased upon entry of the UMWA Order by the Bankruptcy Court effective as of March 31, 2016. The Parent was required under its agreements with the UMWA, specifically the 1974 UMWA Pension Plan, the UMWA Combined Benefit Fund, the UMWA 1992 Benefit Fund, the UMWA 1993 Benefit Plan, and the 2012 Retiree Bonus Plan, to pay amounts based principally on hours worked by UMWA represented employees. Contributions under the UMWA multi-employer pension and benefit plans were set at an aggregate rate of $8.16 per hour worked. Aggregate contributions related to the Predecessor’s employees under these plans were approximately $6.2 million for the three months ended March 31, 2016 (Predecessor). |

Equity Award Plans | Equity Award Plans Warrior Met Coal, LLC 2016 Equity Incentive Plan The Company adopted the Warrior Met Coal, LLC 2016 Equity Incentive Plan (the “2016 Equity Plan”). Under the 2016 Equity Plan, employees, directors and officers of the Company were granted equity interests in Warrior Met Coal, LLC in the form of restricted units and phantom units. In connection with the corporate conversion on April 12, 2017, the awards of restricted units were converted into restricted shares of common stock of the Company (the "Restricted Shares"). The Restricted Shares have certain service-based, performance-based and market-based vesting conditions, including the occurrence of an initial public offering or a change in control as set forth in the 2016 Equity Plan and the applicable award agreements. As of December 31, 2018 , 805,083 Restricted Shares were issued, of which, approximately 25,335 had been forfeited and 630,209 had vested. Upon effectiveness of the 2017 Equity Plan (defined below), no further awards were granted under the 2016 Equity Plan. Holders of phantom shares have the right to receive shares of the Company on the earlier of (i) a change in control as defined by the 2016 Equity Plan or (ii) the fifth anniversary of the grant date of the phantom share. The phantom shares are settled in the Company’s shares. As of December 31, 2018 , there were 43,580 phantom shares issued to a director of the Company, all of which were fully vested upon issuance. Restricted Shares were issued proportionally as Tranche A, Tranche B, and Tranche C shares. The Tranche A shares have service and performance based vesting conditions and the awards vest in equal installments on each of the first five anniversaries of the grant date that occurs prior to an IPO and thereafter, subject to the employee’s continued employment or the director’s continued service with the Company through these dates. Vesting is conditioned and contingent upon at least 50% of the shares originally acquired by Walter Energy’s First Lien Lenders in the Asset Acquisition having been disposed of to an independent third party, whether before or after the IPO. During the second quarter of 2018, certain stockholders of the Company sold in two separate transactions an aggregate of 13,000,000 shares of the Company's common stock in public secondary offerings (see Note 19). In connection with the first of these secondary offerings, the performance based vesting condition was met resulting in approximately $3.6 million of incremental stock compensation expense. The remaining awards shall vest over the remaining time based vesting conditions. As of December 31, 2018 , 98,126 Tranche A shares have vested. In the event of a change in control, any Tranche A shares that have not previously vested shall become fully vested at the time of such change in control, subject to the employee’s continued employment or the director's continued service with the Company through the change in control date. The Tranche B and Tranche C shares are performance and market- based awards, with vesting being contingent upon the achievement of certain market conditions and subject to the employee’s continued employment or the director's continued service with the Company through the date of achievement. In 2017, 532,083 Tranche B and Tranche C shares met the required performance and market conditions and were fully vested. In connection with the vesting of the Tranche B and C shares, the Company recognized approximately $3.2 million in stock compensation expense for the year ended December 31, 2017. The Company also recognized an excess income tax benefit of $3.4 million in connection with this vesting. As of December 31, 2018 , unrecognized compensation expense related to the 2016 Equity Plan amounted to approximately $1.0 million . The following table presents a summary of Restricted Shares granted under the 2016 Equity Plan for the year ended December 31, 2018 : Number of Restricted Class C Shares Weighted Average Grant Date Fair Value Non-vested at December 31, 2017 266,027 $ 21.34 Granted — Forfeited (18,362 ) $ 21.34 Vested (98,126 ) $ 21.34 Outstanding at December 31, 2018 149,539 $ 21.34 The Company used the Black-Scholes option pricing model to estimate the fair value of restricted Tranche A shares granted and the Monte Carlo pricing model to estimate the fair value of restricted Tranche B and C shares granted. The pricing model incorporated the assumptions as presented in the following table, shown at their weighted average values: Successor For the year ended December 31, 2017 For the nine months ended December 31, 2016 Expected stock price volatility (a) 35% 25.25% Risk-free interest rate (b) 1.75% 1.25% Expected life (years) (c) 4.17 5.00 (a) The Company bases its expected volatility on a group of companies believed to be a representative peer group, selected based on industry and market capitalization. (b) The risk-free rate for periods within the expected term of the award is based on the U.S. Government Bond yield with a term equal to the awards' expected term on the date of grant. (c) Expected life represents the period of time that awards granted are expected to be outstanding. Warrior Met Coal, Inc. 2017 Equity Incentive Plan In connection with the IPO, the Company adopted the Warrior Met Coal, Inc. 2017 Equity Incentive Plan (the “2017 Equity Plan”). Awards previously issued and outstanding under the 2016 Equity Plan will continue to be governed by the 2016 Equity Plan. However, no further awards will be granted under the 2016 Equity Plan. Under the 2017 Equity Plan, directors, officers, employees, consultants and advisors and those of affiliated companies, as well as those who have accepted offers of employment or consultancy from the Company or the Company’s affiliated companies, may be granted equity interest in Warrior Met Coal, Inc. in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, stock bonus awards, and performance awards. The total number of shares of common stock, including incentive stock options, available for grant of awards under the 2017 Equity Plan as of December 31, 2018 is 5,657,450 . If any outstanding award expires, is canceled, forfeited, or settled in cash, the shares allocable to that award will again be available for grant under the 2017 Equity Plan. As of December 31, 2018 the equity awards granted under the 2017 Equity Plan are comprised of common stock, restricted stock awards, and restricted stock unit awards. The Company recognized stock compensation expense of $2.1 million for the year ended December 31, 2018 associated with the granting of the awards. Unrecognized compensation expense related to the 2017 Equity Plan amounted to approximately $1.5 million as of December 31, 2018 . A summary of activity related to restricted stock unit award grants under the 2017 Equity Incentive Plan during the year ended December 31, 2018 is as follows: Shares Weighted Average Grant Date Fair Value Non-vested at December 31, 2017 8,823 $ 18.51 Granted 201,512 $ 27.71 Forfeited (15,935 ) $ 27.92 Vested (2,875 ) $ 18.39 Outstanding at December 31, 2018 191,525 $ 27.30 Equity Modification On March 31, 2017, the board of managers of the Company declared a cash distribution payable to holders of our then outstanding Class A Units, Class B Units and Class C Units as of March 27, 2017, resulting in distributions to such holders in the aggregate amount of $190.0 million (the “Special Distribution”). The Special Distribution with respect to such Restricted Shares was not paid but held in trust pending their vesting. As of December 31, 2018 , approximately $5.4 million is held in the trust and is included within other long-term assets in the accompanying Balance Sheets. On June 1, 2017, the Compensation Committee (the "Committee") of the board of directors of the Company (the "Board") approved the modification described below (the “Modification”) to the award agreements (the “Awards”) for the Restricted Shares to certain officers, directors and employees of the Company. Pursuant to the Modification, the Committee waived certain vesting requirements with respect to the Special Distribution for the Restricted Shares such that funds currently held in trust as described above with respect to the Special Distribution were paid in full to recipients that received equal to or less than $100.0 thousand and were paid with respect to 50% of the Restricted Shares for recipients that received greater than $100.0 thousand .

Earnings Per Share [Abstract] | |
Net Income (Loss) per Share | Net Income (Loss) per Share The computation of basic net income (loss) per share is based on the number of weighted average common shares outstanding during the period. The computation of diluted net income (loss) per share is based on the weighted average number of shares outstanding plus the incremental shares that would be outstanding assuming issuance of restricted stock. The number of incremental shares is calculated by applying the treasury stock method. Basic and diluted net income (loss) per share was calculated as follows (in thousands, except per share data): Successor For the year ended For the year ended For the nine months ended December 31, 2018 2017 2016 Numerator: Net income (loss) $ 696,787 $ 455,046 $ (49,673 ) Denominator: Weighted-average shares used to compute net income (loss) per share—basic 52,812 52,800 52,640 Dilutive restricted stock awards and units 106 6 — Weighted-average shares used to compute net income (loss) per share—diluted 52,918 52,806 52,640 Net income (loss) per share—basic $ 13.19 $ 8.62 $ (0.94 ) Net income (loss) per share—diluted $ 13.17 $ 8.62 $ (0.94 ) As of December 31, 2018 , there were 88,809 shares of common stock issued under the 2016 Equity Plan to certain directors and employees, for which the service based vesting conditions were not met as of the measurement date and are included in dilutive earnings per share. There were 109,654 shares granted under the 2017 Equity Plan to certain directors and employees, for which neither the service based nor performance based vesting conditions were met as of the measurement date. As such, these shares have been excluded from basic and diluted earnings per share. As of December 31, 2018 , there were 43,580 shares of common stock contingently issuable upon the settlement of a vested phantom unit award under the 2016 Equity Plan and 13,157 shares of common stock contingently issuable upon the settlement of a vested restricted stock unit award under the 2017 Equity Plan. The settlement date is the earlier of a change in control as described in the 2016 Equity Plan and 2017 Equity Plan or five years from the grant date.

Segment Reporting [Abstract] | |
Segment Information | Segment Information The Company identifies a business as an operating segment if: i) it engages in business activities from which it may earn revenues and incur expenses; ii) its operating results are regularly reviewed by the Chief Operating Decision Maker (“CODM”), who is the Company’s Chief Executive Officer, to make decisions about resources to be allocated to the segment and assess its performance; and iii) it has available discrete financial information. The Company has determined that its two underground mining operations are its operating segments. The CODM reviews financial information at the operating segment level to allocate resources and to assess the operating results and financial performance for each operating segment. Operating segments are aggregated into a reportable segment if the operating segments have similar quantitative economic characteristics and if the operating segments are similar in the following qualitative characteristics: i) nature of products and services; ii) nature of production processes; iii) type or class of customer for their products and services; iv) methods used to distribute the products or provide services; and v) if applicable, the nature of the regulatory environment. The Company has determined that the two operating segments are similar in both quantitative and qualitative characteristics and thus the two operating segments have been aggregated into one reportable segment. The Company has determined that its natural gas and royalty businesses did not meet the criteria in ASC 280 to be considered as operating or reportable segments. Therefore, the Company has included their results in an “all other” category as a reconciling item to consolidated amounts. The Company does not allocate all of its assets, or its depreciation and depletion expense, selling, general and administrative expenses, other post-retirement benefits, transactions costs, restructuring costs, interest expense, reorganization items, net and income tax expense by segment.

Summary of Significant Accoun_2
Summary of Significant Accounting Policies (Policies) | 12 Months Ended |

Accounting Policies [Abstract] | |
Basis of Presentation | The accompanying financial statements have been presented on a consolidated basis for the “Successor” periods subsequent to the Asset Acquisition, which include the year ended December 31, 2018 , the year ended December 31, 2017 , and the nine months ended December 31, 2016, and on a combined basis for the “Predecessor” periods prior to the Asset Acquisition, which includes the three months ended March 31, 2016. The financial information of the Company has been separated by a vertical line on the face of the financial statements to identify these different bases of accounting for Predecessor and Successor periods. |
Use of Estimates | Use of Estimates The Company prepares its financial statements in conformity with GAAP, which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the periods presented. Due to the inherent uncertainty involved in making estimates, actual results could differ from those estimates. |
Concentrations of Credit Risk and Major Customers | Concentrations of Credit Risk and Major Customers Credit is extended based on an evaluation of the individual customer’s financial condition. In some instances, the Company requires letters of credit, cash collateral or prepayments from its customers on or before shipment to mitigate the risk of loss. |
Revenue Recognition | Revenue Recognition The Company adopted Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers”, as of January 1, 2018, using the modified retrospective approach. The Company applied the standard to all customer contracts entered into as of the date of initial application. The Company concluded that the adoption did not change the timing at which the Company historically recognized revenue nor did it have a material impact on its consolidated financial statements. For periods prior to January 1, 2018, revenue was recognized when the following criteria had been met: (i) persuasive evidence of an arrangement existed; (ii) the price to the buyer was fixed or determinable; (iii) delivery had occurred; and (iv) collectability was reasonably assured. Delivery is considered to have occurred at the time title and risk of loss transfers to the customer. For coal shipments to domestic customers via rail, delivery occurs when the railcar is loaded. For coal shipments to international customers via ocean vessel, delivery occurs when the vessel is loaded at the Port of Mobile, Alabama. For natural gas sales, delivery occurs when the gas has been transferred to the pipeline. For periods subsequent to January 1, 2018, revenue is recognized when performance obligations under the terms of a contract with our customers are satisfied; for all contracts this occurs when control of the promised goods have been transferred to our customers. For coal shipments to domestic customers via rail, control is transferred when the railcar is loaded. For coal shipments to international customers via ocean vessel, control is transferred when the vessel is loaded at the Port of Mobile, Alabama. For natural gas sales, control is transferred when the gas has been transferred to the pipeline. Revenue is disaggregated between coal sales within the Company's mining segment and natural gas sales included in all other revenues, as disclosed in Note 23. Our coal and gas sales generally include up to 45-day payment terms following the transfer of control of the goods to the customer. We typically do not include extended payment terms in our contracts with customers. |
Shipping and Handling | Shipping and Handling Costs incurred to transport coal to the point of sale at the Port of Mobile, Alabama, are included in cost of sales and the gross amounts billed to customers, if any, to cover shipping and handling to the ultimate/final destination are included in sales. |
Cash and Cash Equivalents and Restricted Cash | Cash and Cash Equivalents and Restricted Cash Cash and cash equivalents include short-term deposits and highly liquid investments that have original maturities of three months or less when purchased and are stated at cost, which approximates fair value. As of December 31, 2018 and December 31, 2017 , restricted cash included in other long-term assets in the Balance Sheet represents amounts invested in certificate of deposits as financial assurance for post mining reclamation obligations. |
Short-Term Investments | Short-Term Investments Instruments with maturities greater than three months, but less than twelve months, are included in short-term investments. The Company purchases United States Treasury bills with maturities ranging from six to twelve months which are classified as held to maturity and are carried at amortized cost, which approximates fair value. Securities classified as held to maturity securities are those securities that management has the intent and ability to hold to maturity. |
Inventories | Inventories Inventories are valued at the lower of cost or net realizable value. Coal inventory costs include labor, supplies, equipment costs, operating overhead, freight, royalties, depreciation and depletion and other related costs. Coal inventories are valued using the first-in, first-out (“FIFO”) inventory valuation method. The valuation of coal inventories is subject to estimates due to possible gains and losses resulting from inventory movements from the mine site to storage facilities, inherent inaccuracies in belt scales and aerial surveys used to measure quantities and fluctuations in moisture content. Periodic adjustments to coal tonnages on hand are made for an estimate of coal shortages and overages due to these inherent gains and losses, primarily based on historical results from aerial surveys and periodic coal pile clean-ups. Supplies inventories are valued using the average cost method of accounting. Management evaluates its supplies inventory in terms of excess and obsolete exposures which includes such factors as anticipated usage, inventory turnover, inventory levels and ultimate market value. A reserve for excess and obsolete supplies inventory is established and charged to cost of sales in the Statements of Operations. |
Deferred Longwall Move Expenses and Advanced Mining Royalties | Deferred Longwall Move Expenses Direct costs, including labor and supplies, associated with moving longwall equipment and the related equipment refurbishment costs are deferred and included in prepaid expenses. These deferred costs are amortized on a unit-of-production basis into cost of sales over the life of the subsequent panel of coal mined by the longwall equipment. See Note 5 for further disclosures related to deferred longwall move expenses. Advanced Mining Royalties Lease rights to coal reserves are often acquired in exchange for royalty payments. Advance mining royalties are advance payments made to lessors under terms of mineral lease agreements that are recoupable against future production royalties. These advance payments are deferred and charged to operations as the coal reserves are mined. Advance mining royalties are included in other long-term assets. |
Property, Plant and Equipment | Property, Plant and Equipment Property, Plant and Equipment Property, plant and equipment are recorded at cost. Depreciation is recorded principally on the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized on the straight-line method over the lesser of the useful life of the improvement or the remaining lease term. Estimated useful lives used in computing depreciation expense range from three to ten years for machinery and equipment, and from fifteen to thirty years for land improvements and buildings. Well life is used to estimate the useful life for gas properties and related development, and mine life is used for amortizing mine development costs. Gains and losses upon disposition are reflected in the Statements of Operations in the period of disposition. Maintenance and repair expenditures are charged to cost of sales as incurred. Deferred Mine Development Costs of developing new underground mines and certain underground expansion projects are capitalized. Underground development costs, which are costs incurred to make the coal physically accessible, may include construction permits and licenses, mine design, construction of access roads, main entries, airshafts, roof protection and other facilities. Mine development costs are amortized primarily on a unit-of-production basis over the estimated reserve tons directly benefiting from the capital expenditures. Costs amortized during the production phase of a mine are capitalized into inventory and expensed to cost of sales as the coal is sold. Owned and Leased Mineral Interests Costs to obtain coal reserves and lease mineral rights are capitalized based on cost or the fair value at acquisition and depleted using the unit-of-production method over the life of proven and probable reserves. Lease agreements are generally long-term in nature (original terms range from 10 to 50 years) and substantially all of the leases contain provisions that allow for automatic extension of the lease term provided certain requirements are met. Depletion expense was $9.6 million , $ 9.4 million , and $4.5 million for the years ended December 31, 2018 and December 31, 2017 , and the nine months ended December 31, 2016 , respectively, and is included in depreciation and depletion in the accompanying Statements of Operations. There was no depletion expense recorded for the three months ended March 31, 2016 (Predecessor). Asset Retirement Obligations The Company has certain asset retirement obligations primarily related to mine closing reclamation costs, perpetual water care costs and other costs associated with dismantling and removing facilities. Asset retirement obligations are determined for each mine using various estimates and assumptions, including estimates of disturbed acreage as determined from engineering data, estimates of future costs to reclaim the disturbed acreage and the timing of related cash flows, discounted using a credit-adjusted, risk-free rate. The Company's asset retirement obligations also include estimates to reclaim gas well in accordance with the Oil and Gas Board of Alabama. On at least an annual basis, the Company reviews the entire asset retirement obligation liability and makes necessary adjustments for permit changes, the anticipated timing of mine closures, and revisions to cost estimates and productivity assumptions to reflect current experience. As changes in estimates occur, the carrying amount of the obligation and asset are revised to reflect the new estimate after applying the appropriate credit-adjusted, risk-free discount rate. The future costs of these obligations are accrued at the estimated fair value in the period in which it is incurred if a reasonable estimate of fair value can be made. The present value of the estimated asset retirement cost is capitalized as part of the carrying amount of the long-lived asset. For sites where there is no asset, expense or income is recognized for changes in estimates. Capitalized asset retirement costs are amortized on a unit-of-production basis over the estimated reserves. Accretion of the asset retirement obligation is recognized over time and generally will escalate over the life of the producing asset, typically as production declines. Accretion is included in cost of sales on the Statements of Operations. Accrued mine closing costs, perpetual care costs and reclamation costs and other costs of dismantling and removing facilities are regularly reviewed by management and revised for changes in future estimated costs and regulatory requirements, as necessary. For ongoing operations, adjustments to the liability result in an adjustment to the corresponding asset. For some operations, adjustments to the liability are recognized as income or expense in the period the adjustment is recorded as no asset was recorded to offset the liability established during purchase accounting as the operations were idle at that time. Any difference between the recorded obligation and the actual cost of reclamation is recorded in profit or loss in the period the obligation is settled. See Note 9 for further disclosures related to asset retirement obligations. Impairment of Long-Lived Assets Property, plant and equipment and other long-lived assets are reviewed for impairment at least annually or whenever events or changes in circumstances indicate that the book value of the asset may not be recoverable. The Company periodically evaluates whether events and circumstances have occurred that would indicate possible impairment. When impairment indicators exist, the Company uses an estimate of the future undiscounted cash flows of the related asset or asset group over the remaining life in measuring whether or not the asset values are recoverable. If the carrying amount of an asset or asset group exceeds its estimated future cash flows, impairment is recognized equal to the amount by which the carrying amount of the asset exceeds the fair value of the asset or asset group. Fair value is generally determined using market quotes, if available, or a discounted cash flow approach. The Company’s estimate of future undiscounted cash flows is based on assumptions including long-term met coal pricing forecasts, anticipated production volumes and mine operating costs for the life of the mine or estimated useful life of the asset. |
Equity Award Compensation (Successor) and Stock-Based Compensation (Predecessor) | Equity Award Compensation (Successor) The Company accounts for equity award-based compensation to employees and non-employee/directors in accordance with ASC 718 requiring employee equity awards to be accounted for under the fair value method adjusted for estimated forfeitures rates based on historical experience. The Company recognizes compensation expense associated with equity awards for all awards made to employees as the requisite service, performance and market vesting conditions are met. The Company measures compensation expense based on the grant-date fair value of the awards calculated using a Black-Scholes or Monte Carlo valuation model. Compensation expense for equity awards with a service-only condition is recognized over the employee’s requisite service period using a graded vesting method. For awards with a performance condition that affects vesting, the performance condition is not considered in determining the award’s grant-date fair value; however, the performance conditions are considered when estimating the quantity of awards that are expected to vest. No compensation expense is recorded for awards with performance conditions until the performance condition is determined to be probable of achievement. For awards with a market condition that affects vesting, the market condition is considered in determining the award’s grant-date fair value. Compensation expense for awards with a market condition is recognized straight-line over the derived or implied service period. For awards with both performance and market conditions, the market condition is incorporated into the fair value of the award, while the performance condition impacts the timing of expense recognition. Compensation expense for equity awards is included in cost of sales (exclusive of items shown separately below) and selling, general and administrative in the accompanying Statements of Operations. Stock-Based Compensation (Predecessor) Prior to the Asset Acquisition, the Parent periodically granted stock-based awards to its employees and its board of directors. Stock-based compensation expenses related to these awards were allocated to the Predecessor based on the awards and terms previously granted to the employees of the Predecessor’s business units or subsidiaries as well as an allocation of the Parent’s corporate employee expenses. The Parent measured stock options and other stock-based awards granted to employees and directors based on the fair value on the date of the grant and recognized compensation expense for those awards, net of estimated forfeitures, over the requisite service period, which was generally the vesting period of the respective award. The Parent recognized compensation expense for only the portion of awards that were expected to vest. In developing a forfeiture rate estimate, the Parent considered its historical experience to estimate pre-vesting forfeitures for service-based awards. The impact of a forfeiture rate adjustment was recognized in full in the period of adjustment, and when the actual forfeiture rate was materially different from the estimate. The Parent used the Black-Scholes option pricing model to value stock option grants and also estimated forfeitures in calculating the expense related to stock-based compensation. The Parent used the Monte Carlo simulation to value its performance share units in calculating the expense related to stock-based compensation. |
Deferred Financing Costs | Deferred Financing Costs The costs to obtain new debt financing or amend existing financing agreements are deferred and amortized to interest expense over the life of the related indebtedness or credit facility using the straight line method. As of December 31, 2018 and December 31, 2017 , respectively, there were $ 3.1 million and $ 2.2 million , respectively, of origination fees related to the ABL Facility (as defined below) in other long-term assets on the accompanying Balance Sheet. As of December 31, 2018 and December 31, 2017 there were $6.8 million and $ 7.8 million , respectively of unamortized deferred financing costs and debt discount, net, related to the Notes (as defined below), which is presented as a net deduction from the carrying amount of the debt recognized in the accompanying Balance Sheet. |
Income Taxes | Income Taxes The Company records a tax provision for the expected tax effects of the reported results of operations. The provision for income taxes is determined using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax impact of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carryforwards. Deferred income tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets and liabilities are expected to be realized or settled. The Company records a valuation allowance to reduce deferred income tax assets to the amount that is believed more likely than not to be realized. When the Company concludes that all or part of the net deferred income tax assets are not realizable in the future, the Company makes an adjustment to the valuation allowance that is charged to earnings in the period that such determination was made. The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. |
Fair Value Measurements | Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three level hierarchy has been established for valuing assets and liabilities based on how transparent (observable) the inputs are that are used to determine fair value, with the inputs considered most observable categorized as Level 1 and those that are the least observable categorized as Level 3. Hierarchy levels are defined as follows: Level 1: Quoted prices in active markets for identical assets and liabilities. Level 2: Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data. Level 3: Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques. |
New Accounting Pronouncements | New Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-02, "Leases (Topic 842)". ASU 2016-02 contains accounting guidance that will require a lessee to recognize a right of use asset and lease liability on the balance sheet for all leases, with the exception of short-term leases. Additional qualitative disclosures along with specific quantitative disclosures will also be required. The Company adopted this standard on January 1, 2019 using the modified retrospective approach. The Company has concluded that the adoption of this standard did not have a material impact on the Company's consolidated financial position and results of operations. |
