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, Inc. (the "Company") is a U.S.-based environmentally and socially minded supplier to the global steel industry. The Company is dedicated entirely to mining non-thermal met coal used as a critical component of steel production by metal manufacturers in Europe, South America and Asia. The Company is a large-scale, low-cost producer and exporter of premium met coal, also known as hard-coking coal ("HCC"), operating highly efficient longwall operations in its underground mines based in Alabama. The HCC that the Company produces from the Blue Creek coal seam contains very low sulfur, has strong coking properties and is of a similar quality to coal referred to as premium HCC produced in Australia. 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. Basis of Presentation The accompanying financial statements are presented in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, the financial statements include all adjustments (consisting of normal recurring accruals) necessary in order to make the financial statements not misleading. For further information, refer to the financial statements and related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 (the "2022 Annual Report"). Operating results for the three and nine months ended September 30, 2023 are not necessarily indicative of the final results that may be expected for the year ended December 31, 2023. The balance sheet at December 31, 2022 has been derived from the audited financial statements for the year ended December 31, 2022 included in the 2022 Annual Report. Collective Bargaining Agreement The Company's Collective Bargaining Agreement ("CBA") with the labor union representing certain of the Company's hourly employees expired on April 1, 2021 and the labor union initiated a strike after an agreement on a new contract was not reached. As a result of the strike, the Company initially idled Mine No. 4 and scaled back operations at Mine No. 7. In the first quarter of 2022, the Company restarted operations at Mine No. 4. Due to the reduced operations at Mine No. 4 and Mine No. 7, the Company incurred idle mine expenses of $5.4 million and $10.1 million for the three and nine months ended September 30, 2022. The Company incurred no idle mine expenses for the three and nine months ended September 30, 2023. These expenses are reported separately in the Condensed Statements of Operations and represent expenses incurred, such as electricity, insurance and maintenance labor. The Company incurred business interruption expenses of approximately $0.3 million and $8.1 million for the three and nine months ended September 30, 2023, which represent ongoing legal expenses associated with ongoing labor negotiations. The Company incurred $7.1 million and $20.1 million for the three and nine months ended September 30, 2022, which represent non-recurring expenses that were directly attributable to the labor strike for incremental safety and security, labor negotiations and other expenses. These expenses are also presented separately in the Condensed Statements of Operations. On February 16, 2023, the labor union representing certain of the Company's hourly employees announced that they were ending the strike and made an unconditional offer to return to work. The return-to-work process for eligible employees who wished to return to work which began in February and has been completed. The Company continues to engage in good faith efforts with the labor union to reach an agreement on a new contract. Acquisitions On March 31, 2023, the Company acquired the remaining ownership interest in gas wells owned by an independent third party for $2.4 million. The purchase consideration has been preliminarily allocated to the assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. A full and detailed valuation of the assets and liabilities is being completed. Accordingly, the allocation is preliminary and may change as additional information becomes available and is assessed by the Company. The final allocation of the consideration transferred may include adjustments to the fair value estimates of identifiable assets and liabilities after a full review has been completed. The acquisition is not deemed to be material to the condensed financial statements. On March 1, 2022, the Company acquired the remaining 50% interest in Black Warrior Methane ("BWM") and Black Warrior Transmission ("BWT") for $0.3 million. The purchase consideration has been allocated to the assets acquired and

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The Company's significant accounting policies are consistent with those disclosed in Note 2 to its audited financial statements included in the 2022 Annual Report. Cash and Cash Equivalents 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. Short-Term Investments Instruments with maturities greater than three months, but less than twelve months, are included in short-term investments. The Company also purchases fixed income securities and certificates of deposits with varying maturities that are classified as available for sale and are carried at fair value. Securities classified as held to maturity are those securities that management has the intent and ability to hold to maturity. As of September 30, 2023 and December 31, 2022, short-term investments consisted of $8.9 million and $8.6 million in cash and fixed income securities. The short-term investments are posted as collateral for the self-insured black lung related claims asserted by or on behalf of former employees of Walter Energy, Inc. ("Walter Energy") and its subsidiaries, which were assumed by the Company and relate to periods prior to March 31, 2016. Revenue Recognition Revenue is recognized when performance obligations under the terms of a contract with the Company's customers are satisfied; for all contracts this occurs when control of the promised goods has been transferred to its 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 which is included in all other revenues, as disclosed in Note 13. Since February 2017, the Company has had an arrangement with XCoal Energy & Resources ("XCoal") to serve as XCoal's strategic partner for exports of low-volatility HCC typically to the Asian region. Under this arrangement, XCoal takes title to and markets coal that the Company would historically have sold on the spot market, in an amount of the greater of (i) 10% of the Company's total production during the applicable term of the arrangement or (ii) 250,000 metric tons. During the three and nine months ended September 30, 2023 and 2022, XCoal accounted for approximately $36.7 million, or 7.3% and $126.8 million or 9.8% of total sales, and $69.8 million, or 20.6% and $281.3 million or 20.7% of total sales, respectively. Trade Accounts Receivable and Allowance for Credit Losses Trade accounts receivable represent customer obligations that are derived from revenue recognized from contracts with customers. Credit is extended based on an evaluation of the individual customer's financial condition. The Company maintains trade credit insurance on the majority of its customers and the geographic regions of coal shipments to these customers. 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 the Company recognizing no historical credit losses. The Company also has never had to have a claim against its trade credit insurance policy. In order to estimate the allowance for credit losses on trade accounts receivable, the Company utilizes an aging approach in which potential impairment is calculated based on how long a receivable has been outstanding (e.g., current, 1-31 days, 31-60 days, etc.). The Company calculates an expected credit loss rate based on the Company’s historical credit loss rate, the risk characteristics of our customers, and the current met coal and steel market environments. As of September 30, 2023 and December 31, 2022, the estimated allowance for credit losses was immaterial and did not have a material impact on the Company's financial statements.

Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesFor the three and nine months ended September 30, 2023 and 2022, the Company estimated its annual effective tax rate and applied this effective tax rate to its year-to-date pretax income at the end of the interim reporting period. The tax effect of unusual or infrequently occurring items, including the effects of changes in tax laws or rates and changes in judgment about the realizability of deferred tax assets, are reported in the interim period in which they occur. For the three and nine months ended September 30, 2023, the Company had income tax expense of $16.8 million and $60.4 million, respectively. The $16.8 million and $60.4 million income tax expense for the three and nine months ended September 30, 2023, includes a benefit related to depletion and Internal Revenue Code ("IRC") Section 250 Deduction: Foreign-Derived Intangible Income ("FDII"). The Tax Cuts and Jobs Act ("TCJA") was enacted on December 22, 2017 and enacted IRC Section 250 Deduction: FDII, which provides for, among other things, a deduction of 37.5% with respect to foreign-derived intangible income, which reduces the statutory tax rate from 21% to 13.125%. Beginning in 2026, the deduction is reduced from 37.5% to 22.5% of foreign-derived intangible income. The Company has historically not been eligible to claim the deduction due to the deduction being limited to taxable income and the Company's ability to utilize its net operating losses to offset taxable income.

Senior Secured Notes On December 6, 2021, the Company issued $350.0 million in aggregate principal amount of 7.875% senior secured notes due 2028 (the “Notes”) at an initial price of 99.343% of their face amount. The Notes were issued to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to certain non-U.S. persons in transactions outside the United States in accordance with Regulation S under the Securities Act. The Company used the net proceeds of the offering of the Notes, together with cash on hand, to fund the redemption of all of the Company’s outstanding 8.00% senior secured notes due 2024 (the “Existing Notes”), including payment of the redemption premium in connection with such redemption. The Notes will mature on December 1, 2028. During the nine months ended September 30, 2023, the Company repurchased in the open market and extinguished approximately $8.0 million principal amount of our Notes. In connection with the extinguishment of our Notes, we recognized a loss on early extinguishment of debt of $0.1 million which is included in interest income (expense), net in the Condensed Statements of Operations. Offers to Purchase the Notes On August 9, 2023, the Company commenced an offer to purchase (the “Restricted Payment Offer”), in cash, up to $150,000,000 principal amount of its outstanding Notes, at a repurchase price of 103% of the aggregate principal amount of such Notes, plus accrued and unpaid interest with respect to such Notes to, but not including, the date of repurchase (the “Restricted Payment Repurchase Price”). Concurrently with, but separate from, the Restricted Payment Offer, the Company commenced a cash tender offer (the “Tender Offer” and, together with the Restricted Payment Offer, the “Offers”) to purchase up to $150,000,000 principal amount of the Notes at a repurchase price of 104.25% of the aggregate principal amount of such Notes, plus accrued and unpaid interest to, but not including, the date of repurchase (the “TO Repurchase Price”). The Offers expired on September 7, 2023 (the “Expiration Date”). Restricted Payment Offer As of the Expiration Date, $200,000 aggregate principal amount of the Notes were validly tendered and not validly withdrawn pursuant to the Restricted Payment Offer.

The Company consummated the Restricted Payment Offer on September 8, 2023. Accordingly, pursuant to the terms of the Indenture, the Company will have the ability from time to time in the future to make one or more restricted payments (the "Proposed Restricted Payment") in the form of special dividends to holders of the Company’s common stock and/or repurchases of the Company’s common stock in the aggregate amount of up to $299,901,000 consistent with the terms of the Capital Allocation Policy adopted by the Company's board of directors (the "Board"). Any future Proposed Restricted Payments will be at the discretion of the Board and subject to a number of factors and there can be no assurance that the Company will make any Proposed Restricted Payments in the future. Tender Offer As of the Expiration Date, $294,770,000 aggregate principal amount of the Notes were validly tendered and not validly withdrawn pursuant to the Tender Offer. Pursuant to the terms of the Tender Offer: (1) an automatic pro ration factor of 49.5674% was applied to the $294,770,000 aggregate principal amount of the Notes that were validly tendered and not validly withdrawn in the Tender Offer (rounded down to avoid the purchase of Notes in a principal amount other than in integrals of $1,000), which resulted in $146,002,000 aggregate principal amount of the Notes (the “TO Pro-Rated Tendered Notes”); (2) the Company accepted all $146,002,000 aggregate principal amount of the TO Pro-Rated Tendered Notes for payment of the TO Repurchase Price in cash; and (3) the remaining balance of $148,768,000 aggregate principal amount of the Notes tendered that were not TO Pro-Rated Tendered Notes were not accepted for payment and were returned to the tendering holder of the Notes.

ABL Facility On December 6, 2021, the Company entered into the Second Amended and Restated Asset-Based Revolving Credit Agreement (the “Second Amended and Restated Credit Agreement”), by and among the Company and certain of its subsidiaries, as borrowers, the guarantors party thereto, the lenders from time to time party thereto and Citibank, as administrative agent (in such capacity, the "Agent"), which amends and restates in its entirety the then existing Amended and Restated Asset-Based Revolving Credit Agreement (as amended, the “ABL Facility”). The Second Amended and Restated Credit Agreement, among other things, (i) extended the maturity date of the ABL Facility to December 6, 2026; (ii) changed the calculation of the interest rate payable on borrowings from being based on a London Inter-Bank Offered Rate to be based on a SOFR, with corresponding changes to the applicable interest rate margins with respect to such borrowings, (iii) amended certain definitions related to the calculation of the borrowing base; (iv) increased the commitments that may be used to issue letters of credit to $65.0 million; and (v) amended certain baskets contained in the covenants to conform to the baskets contained in the indenture governing the Notes (the "Indenture"). The Second Amended and Restated Credit Agreement also allows the Company to borrow up to $132.0 million through October 13, 2023, decreasing to $116.0 million through November 2026, subject to availability under the borrowing base and other conditions. As of September 30, 2023, no loans were outstanding under the ABL Facility and there were $8.7 million of letters of credit issued and outstanding under the ABL Facility. At September 30, 2023, the Company had $123.3 million of availability under the ABL Facility (calculated net of $8.7 million of letters of credit outstanding at such time).

Commitments and Contingencies	Commitments and Contingencies Environmental Matters The Company is subject to a wide variety of laws and regulations concerning the protection of the environment, both with respect to the construction and operation of its plants, mines and other facilities and with respect to remediating environmental conditions that may exist at its own and other properties. The Company believes it is in compliance with federal, state and local environmental laws and regulations. The Company accrues for environmental expenses resulting from existing conditions that relate to past operations when the costs are probable and can be reasonably estimated. As of September 30, 2023 and December 31, 2022, there were no accruals for environmental matters other than asset retirement obligations for mine reclamation. Miscellaneous Litigation From time to time, the Company is party to lawsuits arising in the ordinary course of business. The Company records costs relating to these matters when a loss is probable and the amount can be reasonably estimated. The effect of the outcome of these matters on the Company’s future results of operations cannot be predicted with certainty as any such effect depends on future results of operations and the amount and timing of the resolution of such matters. As of September 30, 2023 and December 31, 2022, there were no items accrued for miscellaneous litigation. On July 15, 2015, Walter Energy and certain of its wholly owned U.S. subsidiaries, including Jim Walter Resources, Inc. (“JWR”) filed voluntary petitions for relief under chapter 11 of title 11 of the U.S. Bankruptcy Code (the “Chapter 11 Cases”) in the Northern District of Alabama, Southern Division. On December 7, 2015, Walter Energy Canada Holdings, Inc., Walter Canadian Coal Partnership and their Canadian affiliates (collectively “Walter Canada”) applied for and were granted protection under the Companies’ Creditors Arrangement Act (the “CCAA”) pursuant to an Initial Order of the Supreme Court of British Columbia. As a result of the Company’s acquisition of certain core operating assets of Walter Energy during the Chapter 11 Cases, in the first quarter of 2023 and 2022 the Company received $0.2 million and $0.7 million, respectively, from the Chapter 11 Cases which is reflected as other income in the Condensed Statement of Operations. Other Commitments and Contingencies The Company is party to various transportation and throughput agreements with rail and barge transportation providers and the Alabama State Port Authority. These agreements contain annual minimum tonnage guarantees with respect to coal transported from the mine sites to the Port of Mobile, Alabama, the unloading of rail cars or barges, and the loading of vessels. If the Company does not meet its minimum throughput obligations, which are based on annual minimum amounts, it is required to pay the transportation providers or the Alabama State Port Authority a contractually specified amount per metric ton for the difference between the actual throughput and the minimum throughput requirement. At September 30, 2023 and December 31, 2022, the Company had no liability recorded for minimum throughput requirements. Royalty Obligations

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 and the Blue Creek mine development 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, transactions costs, interest income (expense), and income tax expense or benefit by segment. The following tables include reconciliations of segment information to consolidated amounts (in thousands): For the three months ended September 30, For the nine months ended September 30, 2023 2022 2023 2022 Revenues Mining $ 416,888 $ 371,944 $ 1,288,412 $ 1,377,665 All other 6,599 18,236 24,409 16,323 Total revenues $ 423,487 $ 390,180 $ 1,312,821 $ 1,393,988 For the three months ended September 30, For the nine months ended September 30, 2023 2022 2023 2022 Capital Expenditures Mining $ 37,259 $ 28,031 $ 115,796 $ 94,921 All other 69,266 13,289 195,024 25,101 Total capital expenditures $ 106,525 $ 41,320 $ 310,820 $ 120,022 The Company evaluates the performance of its segment based on Segment Adjusted EBITDA, which is defined as net income adjusted for other revenues, cost of other revenues, depreciation and depletion, selling, general and administrative, business interruption, idle mine, other income, interest income (expense), net, income tax expense, loss on extinguishment of debt and certain transactions or adjustments that the CODM does not consider for the purposes of making decisions to allocate resources among segments or assessing segment performance. Segment Adjusted EBITDA does not represent and should not be considered as an alternative to cost of sales under GAAP and may not be comparable to other similarly titled measures used by other companies.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2023
Accounting Policies [Abstract]
Basis of Presentation	Basis of PresentationThe accompanying financial statements are presented in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, the financial statements include all adjustments (consisting of normal recurring accruals) necessary in order to make the financial statements not misleading.
Cash and Cash Equivalents	Cash and Cash Equivalents 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.
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 also purchases fixed income securities and certificates of deposits with varying maturities that are classified as available for sale and are carried at fair value. Securities classified as held to maturity are those securities that management has the intent and ability to hold to maturity.
Revenue Recognition	Revenue Recognition    Revenue is recognized when performance obligations under the terms of a contract with the Company's customers are satisfied; for all contracts this occurs when control of the promised goods has been transferred to its 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 which is included in all other revenues, as disclosed in Note 13.
Trade Accounts Receivable and Allowance for Credit Losses	Trade Accounts Receivable and Allowance for Credit Losses Trade accounts receivable represent customer obligations that are derived from revenue recognized from contracts with customers. Credit is extended based on an evaluation of the individual customer's financial condition. The Company maintains trade credit insurance on the majority of its customers and the geographic regions of coal shipments to these customers. 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 the Company recognizing no historical credit losses. The Company also has never had to have a claim against its trade credit insurance policy. In order to estimate the allowance for credit losses on trade accounts receivable, the Company utilizes an aging approach in which potential impairment is calculated based on how long a receivable has been outstanding (e.g., current, 1-31 days, 31-60 days, etc.). The Company calculates an expected credit loss rate based on the Company’s historical credit loss rate, the risk characteristics of our customers, and the current met coal and steel market environments. As of September 30, 2023 and December 31, 2022, the estimated allowance for credit losses was immaterial and did not have a material impact on the Company's financial statements.
