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, 2019 and 2018 , the unaudited Consolidated Financial Statements include the accounts of CONSOL Operating and CONSOL Thermal Holdings, wholly owned and controlled subsidiaries. The Partnership is a master limited partnership formed on March 16, 2015 to manage and further develop all of our sponsor's active coal operations in Pennsylvania. As of March 31, 2019 , the Partnership's assets are comprised of a 25% undivided interest in, and operational control over, the Pennsylvania Mining Complex. The Partnership's common units trade on the New York Stock Exchange under the ticker symbol “CCR.” Recent Accounting Pronouncements: In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-15 - Intangibles - Goodwill and Other - Internal Use Software (Subtopic 350-40) to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement (hosting arrangement) by providing guidance for determining when the arrangement includes a software license. The amendments in update 2018-15 align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements of capitalizing implementation cost incurred to develop or obtain internal-use software. These changes will be effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Management is currently evaluating the impact this guidance may have on the Partnership’s financial statements. In August 2018, the FASB issued ASU 2018-14 - Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20) to improve the effectiveness of disclosures in the notes to the financial statements by facilitating clear communication of the information required by GAAP. The amendments modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. These changes will be effective for fiscal years ending after December 15, 2020, including interim periods within those fiscal years. Management is currently evaluating the impact this guidance may have on the Partnership's financial statements. In August 2018, the FASB issued ASU 2018-13 - Fair Value Measurement (Topic 820) to improve the effectiveness of disclosures in the notes to the financial statements by facilitating clear communication of the information required by GAAP. The amendments modify the disclosure requirements on fair value measurements including the consideration of costs and benefits. These changes will be effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Management is currently evaluating the impact this guidance may have on the Partnership's financial statements. In June 2018, the FASB issued ASU 2018-07 - Stock Compensation (Topic 718) Improvements to Nonemployee Share-Based Payment Accounting. The amendments in this update seek to simplify accounting for nonemployee share-based payments by clarifying and improving the areas of the overall measurement objective, measurement date, and awards with performance conditions. This update was adopted during the three months ended March 31, 2019 and did not have a material impact on the Partnership's financial statements. In June 2016, the FASB issued ASU 2016-13 - Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which provides financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this, the amendments in this ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The measurement of expected credit losses will be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. The amendments in this ASU will be applied using a modified-retrospective approach and, for public entities, are effective for fiscal years beginning after December 15, 2019 and interim periods within those annual periods. Management does not expect this update to have a material impact on the Partnership's financial statements.

Revenue from Contract with Customer [Abstract]
Revenue	REVENUE: The following table disaggregates our revenue by major source for the three months ended March 31, 2019 and March 31, 2018 : Three Months Ended March 31, 2019 Three Months Ended March 31, 2018 Coal Revenue $ 83,126 $ 87,752 Freight Revenue 1,665 4,472 Total Revenue from Contracts with Customers $ 84,791 $ 92,224 Our revenue is recognized when title passes to the customer. We have determined that each ton of coal represents a separate and distinct performance obligation. Our coal supply contracts and other sales and operating revenue contracts vary in length from short-term to long-term contracts and do not typically have significant financing components. The estimated transaction price from each of our contracts is based on the total amount of consideration to which we expect to be entitled under the contract. Included in the transaction price for certain coal supply contracts is the impact of variable consideration, including quality price adjustments, handling services, per ton price fluctuations based on certain coal sales price indices and anticipated payments in lieu of shipments. The estimated transaction price for each contract is allocated to our performance obligations based on relative standalone selling prices determined at contract inception. 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 provisions, based upon market-driven or inflationary adjustments, where no additional value is exchanged. Also, some of 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 have been immaterial to our net income. As of and for the three months ended March 31, 2019 and 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 from performance obligations satisfied (or partially satisfied) in previous periods. 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. Contract Balances Contract assets are recorded as trade receivables and reported separately in the Partnership's unaudited Consolidated Balance Sheets from other contract assets as title passes to the customer and the Partnership's right to consideration becomes unconditional. Payments for coal shipments are typically due within two to four weeks of the invoice date. The Partnership typically does not have material contract assets that are stated separately from trade receivables as the Partnership's performance obligations are satisfied as control of the goods or services passes to the customer, thereby granting the Partnership an unconditional right to receive consideration. Contract liabilities relate to consideration received in advance of the satisfaction of the Partnership's performance obligations. Contract liabilities are recognized as revenue at the point in time when control of the good or service passes to the customer.

Net Income Per Limited Partner

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, 2019 2018 Net Income $ 15,220 $ 21,957 Less: General Partner Interest in Net Income 257 372 Net Income Allocable to Limited Partner Units $ 14,963 $ 21,585 Limited Partner Interest in Net Income - Common Units $ 8,676 $ 12,477 Limited Partner Interest in Net Income - Subordinated Units 6,287 9,108 Limited Partner Interest in Net Income - Basic & Diluted $ 14,963 $ 21,585 Weighted Average Limited Partner Units Outstanding - Basic Common Units 15,978,105 15,871,477 Subordinated Units 11,611,067 11,611,067 Total 27,589,172 27,482,544 Weighted Average Limited Partner Units Outstanding - Diluted Common Units 16,034,630 15,956,623 Subordinated Units 11,611,067 11,611,067 Total 27,645,697 27,567,690 Net Income Per Limited Partner Unit - Basic Common Units $ 0.54 $ 0.79 Subordinated Units $ 0.54 $ 0.78 Net Income Per Limited Partner Unit - Basic $ 0.54 $ 0.79 Net Income Per Limited Partner Unit - Diluted Common Units $ 0.54 $ 0.78 Subordinated Units $ 0.54 $ 0.78 Net Income Per Limited Partner Unit - Diluted $ 0.54 $ 0.78 There were zero 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, 2019 . There were 129,850 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 .

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, 2019 and December 31, 2018 , property, plant and equipment includes gross assets under finance lease of $ 11,894 and $ 11,919 , respectively. Accumulated amortization for finance leases was $ 4,460 and $ 3,529 at March 31, 2019 and December 31, 2018 , respectively. Amortization expense for assets under finance leases approximated $967 and $327 for the three months ended March 31, 2019 and March 31, 2018 , respectively, and is included in Depreciation, Depletion and Amortization in the accompanying unaudited Consolidated Statements of Operations.

Leases

Leases	3 Months Ended
	Mar. 31, 2019
Leases [Abstract]
Leases	LEASES: On January 1, 2019, the Partnership adopted Accounting Standards Codification (“ASC”) Topic 842 using the transition option, “Comparatives Under 840 Option,” established by ASU 2018-11, Leases (Topic 842), Targeted Improvements. As allowed under this guidance, the Partnership elected not to recast the comparative periods presented when transitioning to ASC 842. As most of the Partnership's leases do not provide an implicit rate, CONSOL Coal Resources has taken a portfolio approach of applying its incremental borrowing rate based on the information available at the adoption date to calculate the present value of lease payments over the lease term. The Partnership has elected the package of practical expedients permitted under the transition guidance within the standard, which allows the Partnership (1) to not reassess whether any expired or existing contracts are or contain leases, (2) to not reassess the lease classification for any expired or existing leases, and (3) to not reassess initial direct costs for any existing leases. The Partnership has also elected the practical expedient to not evaluate land easements that existed or expired before its adoption of Topic 842 and the practical expedient to not separate lease and non-lease components; that is, to account lease and non-lease components in a contract as a single lease component for all classes of underlying assets. Further, the Partnership made an accounting policy election to keep leases with an initial term of twelve months or less off the balance sheet. CONSOL Coal Resources will recognize those lease payments in the unaudited Consolidated Statements of Operations over the lease term. For the three months ended March 31, 2019, these short term lease expenses were not material to the Partnership's financial statements. Based on the Partnership's lease portfolio, the standard had a material impact on the Partnership’s unaudited Consolidated Balance Sheet, but did not have a significant impact on the Partnership’s consolidated net earnings and cash flows. The most significant impact was the recognition of Right of Use (“ROU”) assets and lease liabilities for operating leases, while the accounting for finance leases remained substantially unchanged. The Partnership's bank covenants were not affected by this update. The Partnership recorded operating lease ROU assets and operating lease liabilities of $ 20 million as of January 1, 2019, primarily related to mining equipment, based on the present value of the future lease payments on the date of adoption. The Partnership determines if an arrangement is an operating or finance lease at inception of the applicable lease. For leases where the Partnership is the lessee, ROU assets represent the Partnership’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of the Partnership’s leases do not provide an implicit interest rate, the Partnership uses its incremental borrowing rate based on the information available on the commencement date in determining the present value of lease payments. The ROU asset also consists of any prepaid lease payments, lease incentives received, and costs which will be incurred in exiting a lease. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Partnership will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while the expense for finance leases is recognized as depreciation expense and interest expense using the interest method of recognition. The Partnership has operating leases for mining or other equipment used in operations and office space. Many leases include one or more options to renew, some of which include options to extend the leases, and some leases include options to terminate or buy out the leases within a set period of time. In certain of the Partnership’s lease agreements, the rental payments are adjusted periodically to reflect actual charges incurred for inflation and/or changes in other indexes. Many of our operating lease payments for mining equipment contain a variable component which is calculated based upon production metrics such as feet of advance or raw tonnage mined. While most of our leases contain clauses regarding the general condition of the equipment upon lease termination, they do not contain residual value guarantees. For the three months ended March 31, 2019, the components of operating lease expense were as follows: Fixed Operating Lease Expense $ 1,642 Variable Operating Lease Expense 763 Total Operating Lease Expense $ 2,405 Supplemental cash flow information related to the Partnership’s operating leases for the three months ended March 31, 2019 was as follows: Cash Paid for Amounts Included in the Measurement of Operating Lease Liabilities $ 936 ROU Assets Obtained in Exchange for Operating Lease Obligations $ — The following table presents the lease balances within the unaudited Consolidated Balance Sheet, weighted average lease term, and weighted average discount rates related to the Partnership’s operating leases as of March 31, 2019: Lease Assets and Liabilities Classification Amount Assets: Operating Lease ROU Assets Other Assets $ 19,190 Liabilities: Current: Operating Lease Liabilities Other Accrued Liabilities $ 4,791 Long-Term: Operating Lease Liabilities Operating Lease Liabilities 15,191 Total Operating Lease Liabilities $ 19,982 Weighted Average Remaining Lease Term (in Years) 4.53 Weighted Average Discount Rate 6.68 % The Partnership also enters into finance leases for mining equipment and automobiles.

Leases	LEASES: On January 1, 2019, the Partnership adopted Accounting Standards Codification (“ASC”) Topic 842 using the transition option, “Comparatives Under 840 Option,” established by ASU 2018-11, Leases (Topic 842), Targeted Improvements. As allowed under this guidance, the Partnership elected not to recast the comparative periods presented when transitioning to ASC 842. As most of the Partnership's leases do not provide an implicit rate, CONSOL Coal Resources has taken a portfolio approach of applying its incremental borrowing rate based on the information available at the adoption date to calculate the present value of lease payments over the lease term. The Partnership has elected the package of practical expedients permitted under the transition guidance within the standard, which allows the Partnership (1) to not reassess whether any expired or existing contracts are or contain leases, (2) to not reassess the lease classification for any expired or existing leases, and (3) to not reassess initial direct costs for any existing leases. The Partnership has also elected the practical expedient to not evaluate land easements that existed or expired before its adoption of Topic 842 and the practical expedient to not separate lease and non-lease components; that is, to account lease and non-lease components in a contract as a single lease component for all classes of underlying assets. Further, the Partnership made an accounting policy election to keep leases with an initial term of twelve months or less off the balance sheet. CONSOL Coal Resources will recognize those lease payments in the unaudited Consolidated Statements of Operations over the lease term. For the three months ended March 31, 2019, these short term lease expenses were not material to the Partnership's financial statements. Based on the Partnership's lease portfolio, the standard had a material impact on the Partnership’s unaudited Consolidated Balance Sheet, but did not have a significant impact on the Partnership’s consolidated net earnings and cash flows. The most significant impact was the recognition of Right of Use (“ROU”) assets and lease liabilities for operating leases, while the accounting for finance leases remained substantially unchanged. The Partnership's bank covenants were not affected by this update. The Partnership recorded operating lease ROU assets and operating lease liabilities of $ 20 million as of January 1, 2019, primarily related to mining equipment, based on the present value of the future lease payments on the date of adoption. The Partnership determines if an arrangement is an operating or finance lease at inception of the applicable lease. For leases where the Partnership is the lessee, ROU assets represent the Partnership’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of the Partnership’s leases do not provide an implicit interest rate, the Partnership uses its incremental borrowing rate based on the information available on the commencement date in determining the present value of lease payments. The ROU asset also consists of any prepaid lease payments, lease incentives received, and costs which will be incurred in exiting a lease. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Partnership will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while the expense for finance leases is recognized as depreciation expense and interest expense using the interest method of recognition. The Partnership has operating leases for mining or other equipment used in operations and office space. Many leases include one or more options to renew, some of which include options to extend the leases, and some leases include options to terminate or buy out the leases within a set period of time. In certain of the Partnership’s lease agreements, the rental payments are adjusted periodically to reflect actual charges incurred for inflation and/or changes in other indexes.

On March 28, 2019, the Affiliated Company Credit Agreement was amended to extend the maturity date from February 27, 2023 to December 28, 2024. 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 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 amounts outstanding under the Partnership's prior credit facility. Additional drawings under the Affiliated Company Credit Agreement are available for general partnership purposes. 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 $113,500 and $112,000 as of March 31, 2019 and December 31, 2018 , respectively. Interest on outstanding borrowings under the Affiliated Company Credit Agreement was accrued at a rate of 3.75% as of March 31, 2019 and December 31, 2018 . 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.

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, 2019 December 31, 2018 Carrying Amount Fair Value Carrying Amount Fair Value Affiliated Company Credit Agreement - Related Party $ 161,500 $ 161,500 $ 163,000 $ 163,000 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 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, 2019 , 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 $89,333 . The instruments are comprised of $301 of letters of credit expiring within one year, $79,846 of environmental surety bonds expiring within the next three years, and $9,186 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.

Receivables Financing Agreement	RECEIVABLES FINANCING AGREEMENT On November 30, 2017, (i) CONSOL 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”). On August 30, 2018, the Securitization was amended, among other things, to extend the scheduled termination date to August 30, 2021. 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, ranging from 2.00% to 2.50% per annum , depending on the total net leverage ratio of CONSOL Energy. 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, 2019 , the Partnership, through CONSOL Thermal Holdings, sold $26,968 of trade receivables to CPCC. The Partnership has not derecognized the receivables due to its continued involvement in the collections efforts.

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 Partnership recognizes forfeitures as they occur. The general partner has granted equity-based phantom units that vest over a period of a recipient’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 compensation expense of $397 and $360 for the three months ended March 31, 2019 and March 31, 2018 , respectively, which is included in Selling, General and Administrative Expense in the unaudited Consolidated Statements of Operations.

CONSOL Energy's Board of Directors approved changing the termination date of the program from June 30, 2019 to June 30, 2020. Also, in accordance with CONSOL Energy’s credit facility covenants, as of March 31, 2019 , CONSOL Energy's limit was raised to a total of $50 million to be used for the purchase of CONSOL Coal Resources LP's outstanding common units in the open market.

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, 2019 and 2018 , the unaudited Consolidated Financial Statements include the accounts of CONSOL Operating and CONSOL Thermal Holdings, wholly owned and controlled subsidiaries.
Recent Accounting Pronouncements	In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-15 - Intangibles - Goodwill and Other - Internal Use Software (Subtopic 350-40) to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement (hosting arrangement) by providing guidance for determining when the arrangement includes a software license. The amendments in update 2018-15 align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements of capitalizing implementation cost incurred to develop or obtain internal-use software. These changes will be effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Management is currently evaluating the impact this guidance may have on the Partnership’s financial statements. In August 2018, the FASB issued ASU 2018-14 - Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20) to improve the effectiveness of disclosures in the notes to the financial statements by facilitating clear communication of the information required by GAAP. The amendments modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. These changes will be effective for fiscal years ending after December 15, 2020, including interim periods within those fiscal years. Management is currently evaluating the impact this guidance may have on the Partnership's financial statements. In August 2018, the FASB issued ASU 2018-13 - Fair Value Measurement (Topic 820) to improve the effectiveness of disclosures in the notes to the financial statements by facilitating clear communication of the information required by GAAP. The amendments modify the disclosure requirements on fair value measurements including the consideration of costs and benefits. These changes will be effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Management is currently evaluating the impact this guidance may have on the Partnership's financial statements. In June 2018, the FASB issued ASU 2018-07 - Stock Compensation (Topic 718) Improvements to Nonemployee Share-Based Payment Accounting. The amendments in this update seek to simplify accounting for nonemployee share-based payments by clarifying and improving the areas of the overall measurement objective, measurement date, and awards with performance conditions. This update was adopted during the three months ended March 31, 2019 and did not have a material impact on the Partnership's financial statements. In June 2016, the FASB issued ASU 2016-13 - Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which provides financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this, the amendments in this ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The measurement of expected credit losses will be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. The amendments in this ASU will be applied using a modified-retrospective approach and, for public entities, are effective for fiscal years beginning after December 15, 2019 and interim periods within those annual periods. Management does not expect this update to have a material impact on the Partnership's financial statements.
Revenue	Our revenue is recognized when title passes to the customer. We have determined that each ton of coal represents a separate and distinct performance obligation. Our coal supply contracts and other sales and operating revenue contracts vary in length from short-term to long-term contracts and do not typically have significant financing components. The estimated transaction price from each of our contracts is based on the total amount of consideration to which we expect to be entitled under the contract. Included in the transaction price for certain coal supply contracts is the impact of variable consideration, including quality price adjustments, handling services, per ton price fluctuations based on certain coal sales price indices and anticipated payments in lieu of shipments. The estimated transaction price for each contract is allocated to our performance obligations based on relative standalone selling prices determined at contract inception. 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 provisions, based upon market-driven or inflationary adjustments, where no additional value is exchanged. Also, some of 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 have been immaterial to our net income. As of and for the three months ended March 31, 2019 and 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 from performance obligations satisfied (or partially satisfied) in previous periods. 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.
Leases	The Partnership determines if an arrangement is an operating or finance lease at inception of the applicable lease. For leases where the Partnership is the lessee, ROU assets represent the Partnership’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of the Partnership’s leases do not provide an implicit interest rate, the Partnership uses its incremental borrowing rate based on the information available on the commencement date in determining the present value of lease payments. The ROU asset also consists of any prepaid lease payments, lease incentives received, and costs which will be incurred in exiting a lease. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Partnership will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while the expense for finance leases is recognized as depreciation expense and interest expense using the interest method of recognition. The Partnership has operating leases for mining or other equipment used in operations and office space. Many leases include one or more options to renew, some of which include options to extend the leases, and some leases include options to terminate or buy out the leases within a set period of time. In certain of the Partnership’s lease agreements, the rental payments are adjusted periodically to reflect actual charges incurred for inflation and/or changes in other indexes. Many of our operating lease payments for mining equipment contain a variable component which is calculated based upon production metrics such as feet of advance or raw tonnage mined. While most of our leases contain clauses regarding the general condition of the equipment upon lease termination, they do not contain residual value guarantees.
