Accounting Policies [Abstract]
Basis of Presentation	BASIS OF PRESENTATION: The accompanying unaudited consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. For the three months ended March 31, 2018 and 2017 , the unaudited Consolidated Financial Statements include the accounts of CONSOL Operating and CONSOL Thermal Holdings, wholly owned and controlled subsidiaries. On November 28, 2017, CONSOL Energy was separated from CNX into an independent, publicly traded coal company via a pro rata distribution of all of CONSOL Energy’s common stock to CNX’s stockholders. CONSOL Energy was originally formed as CONSOL Mining Corporation in Delaware on June 21, 2017 to hold CNX’s coal business including its interest in the Pennsylvania Mining Complex and certain related coal assets, including CNX’s ownership interest in the Partnership and our general partner, CNX’s terminal operations at the Port of Baltimore and undeveloped coal reserves located in the Northern Appalachian, Central Appalachian and Illinois basins and certain related coal assets and liabilities. As part of the separation, CONSOL Mining Corporation changed its name to CONSOL Energy Inc. and its ticker to “CEIX”, CNX changed its name to CNX Resources Corporation and its ticker to “CNX”, the Partnership changed its name to CONSOL Coal Resources LP and its ticker to “CCR” and the general partner changed its name to CONSOL Coal Resources GP LLC. Recent Accounting Pronouncements: In January 2018, the Financial Accounting Standards Board (“FASB”) issued Update 2018-01 - Leases (Topic 842) Land Easement Practical Expedient for Transition to Topic 842. This update, if elected, would not require an entity to reassess the accounting treatment of existing land easements not currently accounted for as a lease under Topic 840. Once an entity adopts Topic 842, it should apply that Topic prospectively to all new (or modified) land easements to determine whether the arrangement should be accounted for as a lease. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments in this update is permitted for all entities. Management is currently evaluating the impact this guidance may have on the Partnership’s financial statements. In February 2016, the FASB issued Update 2016-02 - Leases (Topic 842). This update is intended to improve financial reporting about leasing transactions. This update will require lessees to recognize all leases with terms greater than 12 months on their balance sheet as lease liabilities with a corresponding right-of-use asset. This update maintains the dual model for lease accounting, requiring leases to be classified as either operating or finance, with lease classification determined in a manner similar to existing lease guidance. The basic principle is that leases of all types convey the right to direct the use and obtain substantially all the economic benefits of an identified asset, meaning they create an asset and liability for lessees. Lessees will classify leases as either finance leases (comparable to current capital leases) or operating leases (comparable to current operating leases). Costs for a finance lease will be split between amortization and interest expense, with a single lease expense reported for operating leases. This update also will require both qualitative and quantitative disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments in this update is permitted for all entities. Management is currently evaluating the impact this guidance may have on the Partnership’s financial statements, specifically as it relates to potential embedded leases contained within long-term contracts.

Revenue from Contract with Customer [Abstract]
Revenue	REVENUE: The following table disaggregates our revenue by major source for the period ended March 31, 2018: Three Months Ended March 31, 2018 Coal Revenue $ 87,752 Freight Revenue 4,472 Total Revenue from Contracts with Customers $ 92,224 ASU 2014-09 - Revenue from Contracts with Customers. On January 1, 2018, we adopted the new accounting standard ASC 606, Revenue from Contracts with Customers and all the related amendments (“new revenue standard”) for all contracts using the modified retrospective method. There was no cumulative adjustment to the opening balance of retained earnings as a result of initially applying the new revenue standard. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. We do not expect the adoption of the new revenue standard to have a material impact to our net income on an ongoing basis. Our revenue continues to be recognized when title passes to the customer. Coal Revenue Revenues are recognized when title passes to the customers and the price is fixed and determinable. Generally, title passes when coal is loaded at the central preparation facility and, on occasion, at terminal locations or other customer destinations. Our coal contract revenue per ton is fixed and determinable and adjusted for nominal quality adjustments. Some coal contracts also contain positive electric power price related adjustments in addition to a fixed base price per ton. None of the Partnership's coal contracts allow for retroactive adjustments to pricing after title to the coal has passed. Some of our contracts span multiple years and have annual pricing modification, based upon market-driven or inflationary adjustments, where no additional value is exchanged. Also, our contracts contain favorable electric power price related adjustments, which represent market-driven price adjustments, wherein there is no additional value being exchanged. Management believes that the invoice price is the most appropriate rate at which to recognize revenue. While we do, from time to time, experience costs of obtaining coal customer contracts with amortization periods greater than one year, those costs would be immaterial to our net income. As of and for the three months ended March 31, 2018, we do not have any capitalized costs to obtain customer contracts on our balance sheet nor have we recognized any amortization of previously existing capitalized costs of obtaining customer contracts. Further, the Partnership has not recognized any revenue in the current period that is not a result of current period performance. Freight Revenue Some of our coal contracts require that we sell our coal at locations other than our central preparation plant. The cost to transport our coal to the ultimate sales point is passed through to our customers and we recognize the freight revenue equal to the transportation cost when title of the coal passes to the customer.

Net Income Per Limited Partner

Net Income Per Limited Partner and General Partner Interest	3 Months Ended
	Mar. 31, 2018
Earnings Per Share [Abstract]
Net Income Per Limited Partner and General Partner Interest	NET INCOME PER LIMITED PARTNER AND GENERAL PARTNER INTEREST: The Partnership allocates net income among our general partner and limited partners using the two-class method in accordance with applicable authoritative accounting guidance. Under the two-class method, we allocate our net income to our limited partners and our general partner in accordance with the terms of our Partnership Agreement. We also allocate any earnings in excess of distributions to our limited partners and our general partner in accordance with the terms of our Partnership Agreement. We allocate any distributions in excess of earnings for the period to our general partner and our limited partners based on their respective proportionate ownership interests in us, after taking into account distributions to be paid with respect to the incentive distribution rights, as set forth in the Partnership Agreement. Diluted net income per limited partner unit reflects the potential dilution that could occur if securities or agreements to issue common units, such as awards under the long-term incentive plan, were exercised, settled or converted into common units. When it is determined that potential common units resulting from an award subject to performance or market conditions should be included in the diluted net income per limited partner unit calculation, the impact is reflected by applying the treasury stock method. The following table illustrates the Partnership’s calculation of net income per unit for common units and subordinated units (in thousands, except for per unit information): Three Months Ended March 31, 2018 2017 Net Income $ 21,957 $ 14,066 Less: General Partner Interest in Net Income 372 243 Less: Net Income Allocable to Class A Preferred Units — 1,851 Net Income Allocable to Limited Partner Units $ 21,585 $ 11,972 Net Income Allocable to Common Units - Basic 12,477 6,014 Add: Net Income Allocable to Class A Preferred Units — 1,851 Net Income Allocable to Common Units - Diluted $ 12,477 $ 7,865 Net Income Allocable to Subordinated Units - Basic & Diluted $ 9,108 $ 5,958 Weighted Average Limited Partner Units Outstanding - Basic Common Units 15,871,477 11,681,032 Subordinated Units 11,611,067 11,611,067 Total 27,482,544 23,292,099 Weighted Average Limited Partner Units Outstanding - Diluted Common Units 15,956,623 15,768,733 Subordinated Units 11,611,067 11,611,067 Total 27,567,690 27,379,800 Net Income Per Limited Partner Unit - Basic Common Units $ 0.79 $ 0.51 Subordinated Units $ 0.78 $ 0.51 Net Income Per Limited Partner Unit - Basic $ 0.79 $ 0.51 Net Income Per Limited Partner Unit - Diluted Common Units $ 0.78 $ 0.50 Subordinated Units $ 0.78 $ 0.51 Net Income Per Limited Partner Unit - Diluted $ 0.78 $ 0.50 The outstanding Class A Preferred Units were converted on a one-to-one basis into common units on October 2, 2017, under the terms of the Partnership Agreement. As a result, the Partnership issued an aggregate of 3,956,496 Common Units to CNX and canceled the Class A Preferred Units. Following the conversion of the Class A Preferred Units into Common Units, no Class A Preferred Units are outstanding. There were 129,850 and 369,210 phantom units excluded from the computation of the diluted earnings per unit because their effect would be anti-dilutive for the three months ended March 31, 2018 and March 31, 2017 , respectively.

The duration of the leases vary; however, the lease terms generally are extended automatically to the exhaustion of economically recoverable reserves, as long as active mining continues. Coal interests held by lease provide the same rights as fee ownership for mineral extraction and are legally considered real property interests. As of March 31, 2018 and December 31, 2017 , property, plant and equipment includes gross assets under capital lease of $ 6,050 and $ 625 , respectively. Accumulated amortization for capital leases was $ 634 and $ 473 at March 31, 2018 and December 31, 2017 , respectively. Amortization expense for assets under capital leases approximated $327 and $24 for the three months ended March 31, 2018 and 2017 , respectively, and is included in Depreciation, Depletion and Amortization in the accompanying Consolidated Statements of Operations.

The Affiliated Company Credit Agreement provides for a revolving credit facility in an aggregate principal amount of up to $275,000 to be provided by CONSOL Energy, as lender. In connection with the completion of the separation and the Partnership’s entry into the Affiliated Company Credit Agreement, the Partnership made an initial draw of $200,583 , the net proceeds of which were used to repay the PNC Revolving Credit Facility, to provide working capital for the Partnership following the separation and for other general corporate purposes. Additional drawings under the Affiliated Company Credit Agreement are available for general partnership purposes. The Affiliated Company Credit Agreement matures on February 27, 2023. The collateral obligations under the Affiliated Company Credit Agreement generally mirror the PNC Revolving Credit Facility, including the list of entities that act as guarantors thereunder. The obligations under the Affiliated Company Credit Agreement are guaranteed by the Partnership’s subsidiaries and secured by substantially all of the assets of the Partnership and its subsidiaries pursuant to the security agreement and various mortgages. Interest on outstanding obligations under our Affiliated Company Credit Agreement accrues at a fixed rate ranging from 3.75% to 4.75% , depending on the total net leverage ratio. The unused portion of our Affiliated Company Credit Agreement is subject to a commitment fee of 0.50% per annum. The Partnership had available capacity under the Affiliated Company Credit Agreement of $88,000 and $78,417 as of March 31, 2018 and December 31, 2017 , respectively. Interest on outstanding borrowings under the Affiliated Company Credit Agreement at March 31, 2018 and December 31, 2017 was accrued at a rate of 4.25% . The Affiliated Company Credit Agreement contains certain covenants and conditions that, among other things, limit the Partnership’s ability to: (i) incur or guarantee additional debt; (ii) make cash distributions (subject to certain limited exceptions); provided that we will be able to make cash distributions of available cash to partners so long as no event of default is continuing or would result therefrom; (iii) incur certain liens or permit them to exist; (iv) make particular investments and loans; provided that we will be able to increase our ownership percentage of our undivided interest in the Pennsylvania Mining Complex and make investments in the Pennsylvania Mining Complex in accordance with our ratable ownership; (v) enter into certain types of transactions with affiliates; (vi) merge or consolidate with another company; and (vii) transfer, sell or otherwise dispose of assets. The Partnership is also subject to covenants that require the Partnership to maintain certain financial ratios. For example, the Partnership is obligated to maintain at the end of each fiscal quarter (a) maximum first lien gross leverage ratio of 2.75 to 1.00 and (b) a maximum total net leverage ratio of 3.25 to 1.00 , each of which will be calculated on a consolidated basis for the Partnership and its restricted subsidiaries at the end of each fiscal quarter. At March 31, 2018 , the first lien gross leverage ratio was 1.77 to 1.00 and the total net leverage ratio was 1.77 to 1.00 .

Fair Value of Financial Instruments	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	FAIR VALUE OF FINANCIAL INSTRUMENTS: The Partnership determines the fair value of assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair values are based on assumptions that market participants would use when pricing an asset or liability, including assumptions about risk and the risks inherent in valuation techniques and the inputs to valuations. The fair value hierarchy is based on whether the inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources (including LIBOR-based discount rates), while unobservable inputs reflect the Partnership’s own assumptions of what market participants would use. The fair value hierarchy includes three levels of inputs that may be used to measure fair value as described below. Level One - Quoted prices for identical instruments in active markets. Level Two - The fair value of the assets and liabilities included in Level 2 are based on standard industry income approach models that use significant observable inputs, including LIBOR-based discount rates. Level Three - Unobservable inputs significant to the fair value measurement supported by little or no market activity. The significant unobservable inputs used in the fair value measurement of the Partnership’s third party guarantees are the credit risk of the third party and the third party surety bond markets. In those cases when the inputs used to measure fair value meet the definition of more than one level of the fair value hierarchy, the lowest level input that is significant to the fair value measurement in its totality determines the applicable level in the fair value hierarchy. The following methods and assumptions were used to estimate the fair value for which the fair value option was not elected: Long-term debt: The fair value of long-term debt is measured using unadjusted quoted market prices or estimated using discounted cash flow analyses. The discounted cash flow analyses are based on current market rates for instruments with similar cash flows. The carrying amounts and fair values of financial instruments for which the fair value option was not elected are as follows: March 31, 2018 December 31, 2017 Carrying Amount Fair Value Carrying Amount Fair Value Affiliated Company Credit Agreement - Related Party $ 187,000 $ 187,000 $ 196,583 $ 196,583 The Partnership’s debt obligations are valued through reference to the applicable underlying benchmark rate and, as a result, constitute Level 2 fair value measurements.

Commitments and Contingent Liabilities	3 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	COMMITMENTS AND CONTINGENT LIABILITIES: The Partnership is subject to various lawsuits and claims with respect to such matters as personal injury, wrongful death, damage to property, exposure to hazardous substances, governmental regulations (including environmental remediation), employment and contract disputes and other claims and actions arising out of the normal course of its business. We accrue the estimated loss for these lawsuits and claims when the loss is probable and can be estimated. Our current estimated accruals related to these pending claims, individually and in the aggregate, are immaterial to the financial position, results of operations or cash flows of the Partnership. It is possible that the aggregate loss in the future with respect to these lawsuits and claims could ultimately be material to the financial position, results of operations or cash flows of the Partnership; however, such amounts cannot be reasonably estimated. At March 31, 2018 , the Partnership was contractually obligated to CONSOL Energy for financial guarantees and letters of credit to certain third parties which were issued by CONSOL Energy on behalf of the Partnership. The maximum potential total of future payments that we could be required to make under these instruments is $74,150 . The instruments are comprised of $301 of letters of credit expiring in the next year, $64,212 of environmental surety bonds expiring within the next three years, and $9,637 of employee-related and other surety bonds expiring within the next three years. Employee-related financial guarantees have primarily been provided to support various state workers’ compensation and federal black lung self-insurance programs. Environmental financial guarantees have primarily been provided to support various performance bonds related to reclamation and other environmental issues. Other guarantees have been extended to support insurance policies, legal matters, full and timely payments of mining equipment leases, and various other items necessary in the normal course of business. These amounts have not been reduced for potential recoveries under recourse or collateralization provisions. Generally, recoveries under reclamation bonds would be limited to the extent of the work performed at the time of the default. No amounts related to these financial guarantees and letters of credit are recorded as liabilities on the financial statements. The Partnership’s management believes that these guarantees will expire without being funded, and therefore the commitments will not have a material adverse effect on the financial condition of the Partnership.

Debt Disclosure [Abstract]
Receivables Financing Agreement	RECEIVABLES FINANCING AGREEMENT On November 30, 2017, (i) CONSOL Marine Terminals LLC, formerly known as CNX Marine Terminals LLC, as an originator of receivables, (ii) CPCC, as an originator of receivables and as initial servicer of the receivables for itself and the other originators (collectively, the “Originators”), each a wholly owned subsidiary of CONSOL Energy, and (iii) CONSOL Funding LLC (the “SPV”), as buyer, entered into a Purchase and Sale Agreement (the “Purchase and Sale Agreement”). Concurrently, (i) CONSOL Thermal Holdings, as sub-originator, and (ii) CPCC, as buyer and as initial servicer of the receivables for itself and CONSOL Thermal Holdings, entered into a Sub-Originator Agreement (the “Sub-Originator PSA”). In addition, on that date, the SPV entered into a Receivables Financing Agreement (the “Receivables Financing Agreement”) by and among (i) the SPV, as borrower, (ii) CPCC, as initial servicer, (iii) PNC, as administrative agent, LC Bank and lender, and (iv) the additional persons from time to time party thereto as lenders. Together, the Purchase and Sale Agreement, the Sub-Originator PSA and the Receivables Financing Agreement establish the primary terms and conditions of an accounts receivable securitization program (the “Securitization”). Pursuant to the Securitization, (i) CONSOL Thermal Holdings will sell current and future trade receivables to CPCC and (ii) the Originators will sell and/or contribute current and future trade receivables (including receivables sold to CPCC by CONSOL Thermal Holdings) to the SPV and the SPV will, in turn, pledge its interests in the receivables to PNC, which will either make loans or issue letters of credit on behalf of the SPV. The maximum amount of advances and letters of credit outstanding under the Securitization may not exceed $100,000 . Loans under the Securitization will accrue interest at a reserve-adjusted LIBOR market index rate equal to the one-month Eurodollar rate. Loans and letters of credit under the Securitization also will accrue a program fee and participation fee, respectively, equal to 4.00% per annum . In addition, the SPV paid certain structuring fees to PNC Capital Markets LLC and will pay other customary fees to the lenders, including a fee on unused commitments. The SPV’s assets and credit are not available to satisfy the debts and obligations owed to the creditors of CONSOL Energy, CONSOL Thermal Holdings or any of the Originators. CONSOL Thermal Holdings, the Originators and CPCC as servicer are independently liable for their own customary representations, warranties, covenants and indemnities. In addition, CONSOL Energy has guaranteed the performance of the obligations of CONSOL Thermal Holdings, the Originators and CPCC as servicer, and will guarantee the obligations of any additional originators or successor servicer that may become party to the Securitization. However, neither CONSOL Energy nor its affiliates will guarantee collectability of receivables or the creditworthiness of obligors thereunder. The Securitization contains various customary representations and warranties, covenants and default provisions which provide for the termination and acceleration of the commitments and loans under the Securitization in circumstances including, but not limited to, failure to make payments when due, breach of representation, warranty or covenant, certain insolvency events or failure to maintain the security interest in the trade receivables, and defaults under other material indebtedness. As of March 31, 2018 , the Partnership, through CONSOL Thermal Holdings, sold $30,772 of trade receivables to CPCC. The Partnership has not derecognized the receivables due to its continued involvement in the collections efforts.

Related Party Transactions [Abstract]
Related Party	RELATED PARTY: CONSOL Energy In conjunction with the IPO, the Partnership entered into several agreements, including an omnibus agreement, with CNX. In connection with the PA Mining Acquisition, on September 30, 2016, the then General Partner and the Partnership entered into the First Amended and Restated Omnibus Agreement (the “Amended Omnibus Agreement”) with CNX and certain of its subsidiaries. Under the Amended Omnibus Agreement, CNX would indemnify the Partnership for certain liabilities, including those relating to: • all tax liabilities attributable to the assets contributed to the Partnership in connection with the PA Mining Acquisition (the “First Drop Down Assets”) arising prior to the closing of the PA Mining Acquisition or otherwise related to the Contributing Parties’ contribution of the First Drop Down Assets to the Partnership in connection with the PA Mining Acquisition; and • certain operational and title matters related to the First Drop Down Assets, including the failure to have (i) the ability to operate under any governmental license, permit or approval or (ii) such valid title to the First Drop Down Assets, in each case, that is necessary for the Partnership to own or operate the First Drop Down Assets in substantially the same manner as owned or operated by the Contributing Parties prior to the Acquisition. The Partnership would indemnify CNX for certain liabilities relating to the First Drop Down Assets, including those relating to: • the use, ownership or operation of the First Drop Down Assets; and • the Partnership’s operation of the First Drop Down Assets under permits and/or bonds, letters of credit, guarantees, deposits and other pre-payments held by CNX. The Amended Omnibus Agreement amended the Partnership’s obligations to CNX with respect to the payment of an annual administrative support fee and reimbursement for the provision of certain management and operating services provided by CNX, in each case to reflect structural changes in how those services are provided to the Partnership by CNX. On November 28, 2017, in connection with the separation, the general partner, the Partnership, CNX, CONSOL Energy and certain of its subsidiaries entered into the First Amendment to the First Amended and Restated Omnibus Agreement (the “First Amendment to Omnibus Agreement”), dated September 30, 2016, to, among other things: • add CONSOL Energy as a party to the omnibus agreement; • eliminate the right-of-first offer to the Partnership for the 75% of the Pennsylvania Mining Complex not owned by the Partnership; • effect an assignment of all of CNX’s rights and obligations under the omnibus agreement to CONSOL Energy and remove CNX as a party to and, except with respect to CNX’s obligations under Article II of the omnibus agreement, eliminate all of CNX’s obligations under, the omnibus agreement, as amended by the First Amendment to Omnibus Agreement; and • make certain adjustments to the indemnification obligations of the parties. Charges for services from CONSOL Energy include the following: Three Months Ended 2018 2017 Operating and Other Costs $ 685 $ 872 Selling, General and Administrative Expenses 1,645 717 Total Services from CONSOL Energy $ 2,330 $ 1,589 Operating and Other Costs includes service costs for pension and insurance expenses. Selling, General and Administrative Expenses include charges for incentive compensation, an annual administrative support fee and reimbursement for the provision of certain management and operating services provided by CONSOL Energy. Since November 28, 2017, certain administrative services historically incurred by the Partnership are now incurred by CONSOL Energy and the Partnership's portion is reimbursed to CONSOL Energy. For the period ended March 31, 2018, $2,134 of interest was incurred on the Affiliated Company Credit Agreement, of which $1,951 is included in Interest Expense in the Consolidated Statements of Operations, and $183 was capitalized and included in Property, Plant, and Equipment on the Consolidated Balance Sheets. Interest is calculated based upon a fixed rate, determined quarterly, depending on the total net leverage ratio. For the period ended March 31, 2018 , the weighted average interest rate was 4.25% . See Note 7 - Long-Term Debt for more information. At March 31, 2018 and December 31, 2017 , the Partnership had a net payable to CONSOL Energy in the amount of $935 and $3,071 , respectively. This payable includes reimbursements for business expenses, executive fees, stock-based compensation and other items under the Omnibus Agreement.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Long-Term Incentive Plan	LONG-TERM INCENTIVE PLAN: Under the CONSOL Coal Resources LP 2015 Long-Term Incentive Plan (the “LTIP”), our general partner may issue long-term equity-based awards to directors, officers and employees of our general partner or its affiliates, or to any consultants, affiliates of our general partner or other individuals who perform services for us. These awards are intended to compensate the recipients thereof based on the performance of our common units and their continued service during the vesting period, as well as to align their long-term interests with those of our unitholders. We are responsible for the cost of awards granted under the LTIP and all determinations with respect to awards to be made under the LTIP will be made by the board of directors of our general partner or any committee thereof that may be established for such purpose or by any delegate of the board of directors or such committee, subject to applicable law, which we refer to as the plan administrator. The LTIP limits the number of units that may be delivered pursuant to vested awards to 2,300,000 common units, subject to proportionate adjustment in the event of unit splits and similar events. Common units subject to awards that are canceled, forfeited, withheld to satisfy exercise prices or tax withholding obligations or otherwise terminated without delivery of the common units will be available for delivery pursuant to other awards. The general partner has granted equity-based phantom units that vest over a period of a director’s continued service with the Partnership. The phantom units will be paid in common units or an amount of cash equal to the fair market value of a unit based on the vesting date. The awards may accelerate upon a change in control of the Partnership. Compensation expense is recognized on a straight-line basis over the requisite service period, which is generally the vesting term. The Partnership recognized $360 and $866 of compensation expense for the three months ended March 31, 2018 and March 31, 2017 respectively, which is included in Selling, General and Administrative Expense in the Consolidated Statements of Operations. As of March 31, 2018 , there is $2,978 of unearned compensation that will vest over a weighted average period of 1.60 years. The total fair value of restricted stock units vested during the three months ended March 31, 2018 and March 31, 2017 was $2,419 and $1,134 , respectively. The following represents the nonvested phantom units and their corresponding weighted average grant date fair value: Number of Units Weighted Average Grant Date Fair Value per Unit Nonvested at December 31, 2017 401,409 $ 14.87 Granted 18,807 $ 15.95 Vested (174,005 ) $ 13.90 Forfeited (5,276 ) $ 15.37 Nonvested at March 31, 2018 240,935 $ 15.65

Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. For the three months ended March 31, 2018 and 2017 , the unaudited Consolidated Financial Statements include the accounts of CONSOL Operating and CONSOL Thermal Holdings, wholly owned and controlled subsidiaries.
Recent Accounting Pronouncements	In January 2018, the Financial Accounting Standards Board (“FASB”) issued Update 2018-01 - Leases (Topic 842) Land Easement Practical Expedient for Transition to Topic 842. This update, if elected, would not require an entity to reassess the accounting treatment of existing land easements not currently accounted for as a lease under Topic 840. Once an entity adopts Topic 842, it should apply that Topic prospectively to all new (or modified) land easements to determine whether the arrangement should be accounted for as a lease. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments in this update is permitted for all entities. Management is currently evaluating the impact this guidance may have on the Partnership’s financial statements. In February 2016, the FASB issued Update 2016-02 - Leases (Topic 842). This update is intended to improve financial reporting about leasing transactions. This update will require lessees to recognize all leases with terms greater than 12 months on their balance sheet as lease liabilities with a corresponding right-of-use asset. This update maintains the dual model for lease accounting, requiring leases to be classified as either operating or finance, with lease classification determined in a manner similar to existing lease guidance. The basic principle is that leases of all types convey the right to direct the use and obtain substantially all the economic benefits of an identified asset, meaning they create an asset and liability for lessees. Lessees will classify leases as either finance leases (comparable to current capital leases) or operating leases (comparable to current operating leases). Costs for a finance lease will be split between amortization and interest expense, with a single lease expense reported for operating leases. This update also will require both qualitative and quantitative disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments in this update is permitted for all entities. Management is currently evaluating the impact this guidance may have on the Partnership’s financial statements, specifically as it relates to potential embedded leases contained within long-term contracts.
