BASIS OF PRESENTATION

BASIS OF PRESENTATION	6 Months Ended

Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION: On November 28, 2017, CONSOL Energy was separated from its former parent to become an independent, publicly-traded coal company. As part of the separation, the following assets of the Company's former parent were transferred to CONSOL Energy (collectively, the “Coal Business”): (i) its interest in the Pennsylvania Mining Complex, and certain related coal assets, (ii) its ownership interest in CNX Coal Resources LP, which owns a 25% undivided interest in the PAMC, (iii) the CONSOL Marine Terminal and, (iv) undeveloped coal reserves (Greenfield Reserves) located in the Northern Appalachian, Central Appalachian and Illinois basins and certain related coal assets and liabilities. Following the separation, shares of the Company's common stock began “regular-way” trading on the New York Stock Exchange on November 29, 2017 under the symbol “CEIX”. Basis of Presentation The accompanying Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles 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 accounting principles generally accepted in the United States (“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. Operating results for the three and six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for future periods. The Consolidated Balance Sheet at December 31, 2018 has been derived from the Audited Consolidated Financial Statements at that date but does not include all disclosures required by GAAP. This Form 10-Q report should be read in conjunction with CONSOL Energy Inc.'s Annual Report on Form 10-K for the year ended December 31, 2018 . Basis of Consolidation The Consolidated Financial Statements include the accounts of CONSOL Energy Inc. and its wholly-owned and majority-owned and/or controlled subsidiaries. The portion of these entities that is not owned by the Company is presented as non-controlling interest. All significant intercompany transactions and accounts have been eliminated in consolidation. 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 costs 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 Company’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 Company’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 Company’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 Update 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. In May 2019, the FASB updated Topic 326 by issuing ASU 2019-05, Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief, which provides entities that have certain instruments within the scope of Subtopic 326-20, Financial Instruments-Credit Losses - Measured at Amortized Cost, with an option to irrevocably elect the fair value option in Subtopic 825-10, Financial Instruments-Overall, applied on an instrument-by-instrument basis for eligible instruments, upon adoption of Topic 326. The amendments in these Updates 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 Company's financial statements. Earnings per Share Basic earnings per share are computed by dividing net income attributable to CONSOL Energy Inc. shareholders by the weighted average shares outstanding during the reporting period. Dilutive earnings per share are computed similarly to basic earnings per share, except that the weighted average shares outstanding are increased to include additional shares from restricted stock units and performance share units, if dilutive. The number of additional shares is calculated by assuming that outstanding restricted stock units and performance share units were released, and that the proceeds from such activities were used to acquire shares of common stock at the average market price during the reporting period. The table below sets forth the share-based awards that have been excluded from the computation of diluted earnings per share because their effect would be anti-dilutive: For the Three Months Ended For the Six Months Ended June 30, June 30, 2019 2018 2019 2018 Anti-Dilutive Restricted Stock Units 168,460 21,567 6,860 21,567 Anti-Dilutive Performance Share Units 41,675 — 41,675 — 210,135 21,567 48,535 21,567 The computations for basic and dilutive earnings per share are as follows: For the Three Months Ended For the Six Months Ended Dollars in thousands, except per share data June 30, June 30, 2019 2018 2019 2018 Numerator: Net Income $ 48,830 $ 52,709 $ 69,133 $ 123,667 Less: Net Income Attributable to Noncontrolling Interest 5,550 7,547 11,418 16,097 Net Income Attributable to CONSOL Energy Inc.

Reclassifications Certain amounts in prior periods have been reclassified to conform with the report classifications of the current period, including the reclassification of restricted cash, previously included in Prepaid Expenses and Other Assets on the Consolidated Balance Sheets, as well as the reclassification of amortization of debt issuance costs and loss on debt extinguishment within the Operating Activities section of the Consolidated Statements of Cash Flows. These reclassifications had no effect on previously reported total assets, net income or stockholders' equity.

REVENUE

Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE: The following table disaggregates CONSOL Energy's revenue by major source to depict how the nature, amount, timing and uncertainty of the Company's revenues and cash flows are affected by economic factors: Three Months Ended Six Months Ended June 30, 2019 June 30, 2018 June 30, 2019 June 30, 2018 Coal Revenue $ 350,620 $ 370,697 $ 683,123 $ 721,706 Terminal Revenue 16,708 16,659 34,526 31,880 Freight Revenue 3,854 17,444 10,516 35,331 Total Revenue from Contracts with Customers $ 371,182 $ 404,800 $ 728,165 $ 788,917 CONSOL Energy's coal revenue is recognized when title passes to the customer. The Company has determined that each ton of coal represents a separate and distinct performance obligation. The Company's 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 the Company's contracts is based on the total amount of consideration to which the Company expects 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 the Company's performance obligations based on relative stand-alone selling prices determined at contract inception. Coal Revenue Revenues are recognized at a point in time, which is generally 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. The Company's 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 Company’s coal contracts allow for retroactive adjustments to pricing after title to the coal has passed. Some of the Company's contracts span multiple years and have annual pricing modifications, based upon market-driven or inflationary adjustments, where no additional value is exchanged. Also, some of the Company's 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 CONSOL Energy does, from time to time, experience costs of obtaining coal customer contracts with amortization periods greater than one year, those costs are immaterial to the Company's net income. At June 30, 2019 and December 31, 2018 , the Company did not have any capitalized costs to obtain customer contracts on its Consolidated Balance Sheets. As of and for the three and six months ended June 30, 2019 and 2018 , the Company has not recognized any amortization of previously existing capitalized costs of obtaining customer contracts. Further, the Company has not recognized any revenue in the current period that is not a result of current period performance. Terminal Revenue Terminal revenues are attributable to the Company's CONSOL Marine Terminal and include revenues earned from providing receipt and unloading of coal from rail cars, transporting coal from the receipt point to temporary storage or stockpile facilities located at the Terminal, stockpiling, blending, weighing, sampling, redelivery, and loading of coal onto vessels. Revenues for these services are generally earned on a rateable basis, and performance obligations are considered fulfilled as the services are performed. CONSOL Marine Terminal does not normally experience material costs of obtaining customer contracts with amortization periods greater than one year. At June 30, 2019 and December 31, 2018 , the Company did not have any capitalized costs to obtain customer contracts on its Consolidated Balance Sheets. As of and for the three and six months ended June 30, 2019 and 2018 , the Company has not recognized any amortization of previously existing capitalized costs of obtaining Terminal customer contracts. Further, the Company has not recognized any revenue in the current period that is not a result of current period performance. Freight Revenue Some of CONSOL Energy's coal contracts require that the Company sell its coal at locations other than its central preparation plant. The cost to transport the Company's coal to the ultimate sales point is passed through to the Company's customers and CONSOL Energy recognizes the freight revenue equal to the transportation costs when title of the coal passes to the customer. Contract Balances Contract assets are recorded as trade receivables and reported separately in the Company's Consolidated Balance Sheets from other contract assets as title passes to the customer and the Company's right to consideration becomes unconditional. Payments for coal shipments are typically due within two to four weeks from the invoice date. CONSOL Energy typically does not have material contract assets that are stated separately from trade receivables as the Company's performance obligations are satisfied as control of the goods or services passes to the customer, thereby granting the Company an unconditional right to receive consideration. Contract liabilities relate to consideration received in advance of the satisfaction of the Company'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.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES: The effective tax rate for the three and six months ended June 30, 2019 was (3.9)% and (4.0)% , respectively. The six-month rate is composed of a tax benefit of (3.4)% from operations and a discrete tax benefit of (0.6)% primarily related to equity compensation. The effective tax rate for the three and six months ended June 30, 2019 differs from the U.S. federal statutory rate of 21% , primarily due to the income tax benefit for excess percentage depletion. The effective tax rate for the three and six months ended June 30, 2018 was 5.4% and 6.9% , respectively. The effective tax rate for the three and six months ended June 30, 2018 differs from the U.S. federal statutory rate of 21% , primarily due to the income tax benefit for excess percentage depletion. The Company utilizes the “more likely than not” standard in recognizing a tax benefit in its financial statements. For the six months ended June 30, 2019 and the year ended December 31, 2018 , the Company did not have any unrecognized tax benefits. If accrual for interest or penalties is required, it is the Company's policy to include these as a component of income tax expense. The Company is subject to taxation in the United States, as well as various states, and Canada, as well as various provinces. Under the provisions of the tax matters agreement entered into between the Company and its former parent on November 28, 2017 (the “TMA”), certain subsidiaries of the Company are subject to examination for tax years for the period January 1, 2015 through the six months ended June 30, 2019 for certain state and foreign returns. Further, the Company is subject to examination for the period November 28, 2017 through the six months ended June 30, 2019 for federal and certain state returns.

Short-term Debt [Abstract]
ACCOUNTS RECEIVABLE SECURITIZATION	ACCOUNTS RECEIVABLE SECURITIZATION: CONSOL Energy and certain of its U.S. subsidiaries are parties to a trade accounts receivable securitization facility with financial institutions for the sale on a continuous basis of eligible trade accounts receivable. In August 2018, the securitization facility was amended to, among other things, extend the term of the securitization facility for three years ending August 30, 2021. Pursuant to the securitization facility, CONSOL Thermal Holdings LLC sells current and future trade receivables to CONSOL Pennsylvania Coal Company LLC. CONSOL Marine Terminals LLC and CONSOL Pennsylvania Coal Company LLC sell and/or contribute current and future trade receivables (including receivables sold to CONSOL Pennsylvania Coal Company LLC by CONSOL Thermal Holdings LLC) to CONSOL Funding LLC (the “SPV”). The SPV, in turn, pledges its interests in the receivables to PNC Bank, which either makes loans or issues letters of credit on behalf of the SPV. The maximum amount of advances and letters of credit outstanding under the securitization facility may not exceed $100 million . Loans under the securitization facility 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 facility also accrue a program fee and a letter of credit 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 equal to 0.60% per annum. At June 30, 2019 , the Company's eligible accounts receivable yielded $33,780 of borrowing capacity. At June 30, 2019 , the facility had no outstanding borrowings and $37,695 of letters of credit outstanding, leaving no unused capacity. CONSOL Energy posted $3,915 of cash collateral to secure the difference in the outstanding letters of credit and the eligible accounts receivable. Cash collateral of $3,915 is included in Restricted Cash in the Consolidated Balance Sheets. At December 31, 2018 , the Company's eligible accounts receivable yielded $37,869 of borrowing capacity. At December 31, 2018 , the facility had no outstanding borrowings and $52,536 of letters of credit outstanding, leaving no unused capacity. CONSOL Energy posted $14,667 of cash collateral to secure the difference in the outstanding letters of credit and the eligible accounts receivable. Cash collateral of $14,667 is included in Restricted Cash in the Consolidated Balance Sheets. Costs associated with the receivables facility totaled $370 and $751 for the three and six months ended June 30, 2019 , respectively, and $860 and $1,526 for the three and six months ended June 30, 2018 , respectively. These costs have been recorded as financing fees which are included in Operating and Other Costs in the Consolidated Statements of Income. The Company has not derecognized any receivables due to its continued involvement in the collections efforts.

The duration of the leases vary; however, the lease terms are generally 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 June 30, 2019 and December 31, 2018 , property, plant and equipment includes gross assets under finance leases of $ 49,903 and $ 49,775 , respectively. Accumulated amortization for finance leases was $ 23,571 and $ 15,973 at June 30, 2019 and December 31, 2018 , respectively. Amortization expense for assets under finance leases approximated $3,920 and $3,934 for the three months ended June 30, 2019 and 2018 and $7,834 and $5,309 for the six months ended June 30, 2019 and 2018

LEASES

LEASES	6 Months Ended
	Jun. 30, 2019
Leases [Abstract]
LEASES	LEASES: On January 1, 2019, the Company 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 Company elected not to recast the comparative periods presented when transitioning to ASC 842. As most of the Company's leases do not provide an implicit rate, CONSOL Energy 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. CONSOL Energy has elected the package of practical expedients permitted under the transition guidance within the standard, which allows the Company (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. CONSOL Energy has also elected the practical expedient to not evaluate land easements that existed or expired before the Company’s adoption of Topic 842 and the practical expedient to not separate lease and non-lease components; that is, to account for lease and non-lease components in a contract as a single lease component for all classes of underlying assets. Further, the Company made an accounting policy election to keep leases with an initial term of twelve months or less off the balance sheet. CONSOL Energy will recognize those lease payments in the Consolidated Statements of Income over the lease term. For the three and six months ended June 30, 2019 , these short-term lease expenses were not material to the Company's financial statements. Based on the Company's lease portfolio, the standard had a material impact on the Company’s Consolidated Balance Sheet but did not have a significant impact on the Company’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 Company's bank covenants were not affected by this update. The Company recorded operating lease ROU assets and operating lease liabilities of approximately $92 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 Company determines if an arrangement is an operating or finance lease at inception of the applicable lease. For leases where the Company is the lessee, ROU assets represent the Company’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 Company’s leases do not provide an implicit interest rate, the Company 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 Company 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 Company has operating leases for mining and 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 Company’s lease agreements, the rental payments are adjusted periodically to reflect actual charges incurred for inflation and/or changes in other indexes. Many of the Company's 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 the Company's leases contain clauses regarding the general condition of the equipment upon lease termination, they do not contain residual value guarantees. For the three and six months ended June 30, 2019 , the components of operating lease expense were as follows: Three Months Ended Six Months Ended Fixed operating lease expense $ 6,439 $ 13,296 Variable operating lease expense 3,299 6,351 Total operating lease expense $ 9,738 $ 19,647 Supplemental cash flow information related to the Company's operating leases for the six months ended June 30, 2019 was as follows: Cash paid for amounts included in the measurement of operating lease liabilities $ 7,820 ROU assets obtained in exchange for operating lease obligations — The following table presents the lease balances within the Consolidated Balance Sheet, weighted average lease term, and the weighted average discount rate related to the Company's operating leases at June 30, 2019 : Lease Assets and Liabilities Classification Assets: Operating Lease ROU Assets Other Assets $ 82,105 Liabilities: Current: Operating Lease Liabilities Other Accrued Liabilities $ 15,798 Long-Term: Operating Lease Liabilities Operating Lease Liabilities $ 68,466 Total Operating Lease Liabilities $ 84,264 Weighted average remaining lease term (in years) 5.34 Weighted average discount rate 6.77 % CONSOL Energy leases certain owned mining equipment to a third-party under operating leases.

The Company recorded operating lease ROU assets and operating lease liabilities of approximately $92 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 Company determines if an arrangement is an operating or finance lease at inception of the applicable lease. For leases where the Company is the lessee, ROU assets represent the Company’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 Company’s leases do not provide an implicit interest rate, the Company 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 Company 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 Company has operating leases for mining and 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 Company’s lease agreements, the rental payments are adjusted periodically to reflect actual charges incurred for inflation and/or changes in other indexes. Many of the Company's 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 the Company's leases contain clauses regarding the general condition of the equipment upon lease termination, they do not contain residual value guarantees. For the three and six months ended June 30, 2019 , the components of operating lease expense were as follows: Three Months Ended Six Months Ended Fixed operating lease expense $ 6,439 $ 13,296 Variable operating lease expense 3,299 6,351 Total operating lease expense $ 9,738 $ 19,647 Supplemental cash flow information related to the Company's operating leases for the six months ended June 30, 2019 was as follows: Cash paid for amounts included in the measurement of operating lease liabilities $ 7,820 ROU assets obtained in exchange for operating lease obligations — The following table presents the lease balances within the Consolidated Balance Sheet, weighted average lease term, and the weighted average discount rate related to the Company's operating leases at June 30, 2019 : Lease Assets and Liabilities Classification Assets: Operating Lease ROU Assets Other Assets $ 82,105 Liabilities: Current: Operating Lease Liabilities Other Accrued Liabilities $ 15,798 Long-Term: Operating Lease Liabilities Operating Lease Liabilities $ 68,466 Total Operating Lease Liabilities $ 84,264 Weighted average remaining lease term (in years) 5.34 Weighted average discount rate 6.77 % CONSOL Energy leases certain owned mining equipment to a third-party under operating leases.

In November 2017, CONSOL Energy entered into a revolving credit facility with commitments up to $300 million (the “Revolving Credit Facility”), a Term Loan A Facility of up to $100 million (the “TLA Facility”) and a Term Loan B Facility of up to $400 million (the “TLB Facility”, and together with the Revolving Credit Facility and the TLA Facility, the “Senior Secured Credit Facilities”). On March 28, 2019, the Company amended the Senior Secured Credit Facilities (the “amendment”) to increase the borrowing commitment of the Revolving Credit Facility to $400 million and reallocate the principal amounts outstanding under the TLA Facility and TLB Facility. As a result, the principal amount outstanding under the TLA Facility was $100 million and the principal amount outstanding under the TLB Facility was $275 million . Borrowings under the Company's Senior Secured Credit Facilities bear interest at a floating rate which can be, at the Company's option, either (i) LIBOR plus an applicable margin or (ii) an alternate base rate plus an applicable margin. The applicable margin for the Revolving Credit Facility and TLA Facility depends on the total net leverage ratio, whereas the applicable margin for the TLB Facility is fixed. The amendment reduced the applicable margin by 50 basis points on both the Revolving Credit Facility and the TLA Facility, and by 150 basis points on the TLB Facility. The amendment also extended the maturity dates of the Senior Secured Credit Facilities. The maturity date of the Revolving Credit and TLA Facilities was extended from November 28, 2021 to March 28, 2023. The TLB Facility's maturity date was extended from November 28, 2022 to September 28, 2024. Obligations under the Senior Secured Credit Facilities are guaranteed by (i) all owners of the 75% undivided economic interest in the PAMC held by the Company, (ii) any other members of the Company’s group that own any portion of the collateral securing the Revolving Credit Facility, and (iii) subject to certain customary exceptions and agreed materiality thresholds, all other existing or future direct or indirect wholly owned restricted subsidiaries of the Company (excluding the Partnership and its wholly-owned subsidiaries). The Revolving Credit Facility and TLA Facility also include financial covenants, including (i) a maximum first lien gross leverage ratio, (ii) a maximum total net leverage ratio, and (iii) a minimum fixed charge coverage ratio. CONSOL Energy must maintain a maximum first lien gross leverage ratio covenant of no more than 2.00 to 1.00, measured quarterly, stepping down to 1.75 to 1.00 in March 2020. The maximum first lien gross leverage ratio is calculated as the ratio of Consolidated First Lien Debt to Consolidated EBITDA, excluding the Partnership. The maximum first lien gross leverage ratio was 1.15 to 1.00 at June 30, 2019 . CONSOL Energy must maintain a maximum total net leverage ratio covenant of no more than 3.00 to 1.00, measured quarterly, stepping down to 2.75 to 1.00 in March 2020. The maximum total net leverage ratio is calculated as the ratio of Consolidated Indebtedness, minus Cash on Hand, to Consolidated EBITDA, excluding the Partnership. The maximum total net leverage ratio was 1.74 to 1.00 at June 30, 2019 . Consolidated EBITDA, as used in the covenant calculation, excludes non-cash compensation expenses, non-recurring transaction expenses, extraordinary gains and losses, gains and losses on discontinued operations, non-cash charges related to legacy employee liabilities and gains and losses on debt extinguishment, and includes cash distributions received from the Partnership and subtracts cash payments related to legacy employee liabilities. The facilities also include a minimum fixed charge coverage covenant of no less than 1.10 to 1.00, measured quarterly. The minimum fixed charge coverage ratio is calculated as the ratio of Consolidated EBITDA to Consolidated Fixed Charges, excluding the Partnership. Consolidated Fixed Charges, as used in the covenant calculation, include cash interest payments, cash payments for income taxes, scheduled debt repayments, dividends paid, and Maintenance Capital Expenditures. The minimum fixed charge coverage ratio was 1.52 to 1.00 at June 30, 2019 . The TLB Facility also includes a financial covenant that requires the Company to repay a certain amount of its borrowings under the TLB Facility within ten business days after the date it files its Form 10-K with the Securities and Exchange Commission if the Company has excess cash flow (as defined in the credit agreement for the Senior Secured Credit Facilities) during the year covered by the applicable Form 10-K. During the six months ended June 30, 2019 , CONSOL Energy made the required repayment of approximately $110 million based on the amount of the Company's excess cash flow as of December 31, 2018 . For fiscal year 2018, such repayment was equal to 75% of the Company’s excess cash flow less any voluntary prepayments of its borrowings under the TLB Facility made by the Company during 2018. For all subsequent fiscal years, the required repayment is equal to a certain percentage of the Company’s excess cash flow for such year, ranging from 0% to 75% depending on the Company’s total net leverage ratio, less the amount of certain voluntary prepayments made by the Company, if any, under the TLB Facility during such fiscal year. The amendment reduced the maximum amount of the mandatory annual excess cash flow sweep under the TLB Facility by 25% . At June 30, 2019 , the Revolving Credit Facility had no borrowings outstanding and $58,406 of letters of credit outstanding, leaving $341,594 of unused capacity. At December 31, 2018 , the Revolving Credit Facility had no borrowings outstanding and $54,065 of letters of credit outstanding, leaving $245,935 of unused capacity. From time to time, CONSOL Energy is required to post financial assurances to satisfy contractual and other requirements generated in the normal course of business. Some of these assurances are posted to comply with federal, state or other government agencies' statutes and regulations. CONSOL Energy sometimes uses letters of credit to satisfy these requirements and these letters of credit reduce the Company's borrowing facility capacity. In November 2017, CONSOL Energy issued $300 million in aggregate principal amount of 11.00% Senior Secured Second Lien Notes due 2025 (the “Second Lien Notes”) pursuant to an indenture (the “Indenture”) dated as of November 13, 2017, by and between the Company and UMB Bank, N.A., a national banking association, as trustee and collateral trustee (the “Trustee”). On November 28, 2017, certain subsidiaries of the Company executed a supplement to the Indenture and became party to the Indenture as a guarantor (the “Guarantors”). The Second Lien Notes are secured by second priority liens on substantially all of the assets of the Company and the Guarantors that are pledged and on a first-priority basis as collateral securing the Company’s obligations under the Senior Secured Credit Facilities (described above), subject to certain exceptions under the Indenture. During the six months ended June 30, 2019 , the Company made a required repayment of approximately $110 million on the TLB Facility (discussed above) and amended the Senior Secured Credit Facilities.The Company also repurchased $19 million of its outstanding 11.00% Senior Secured Second Lien Notes due in 2025 during the six months ended June 30, 2019 . As part of these transactions, $1,500 and $24,643 was included in Loss on Debt Extinguishment on the Consolidated Statements of Income for the three and six months ended June 30, 2019 , respectively. During the six months ended June 30, 2018 , CONSOL Energy made accelerated payments of $18.75 million on its outstanding TLA Facility and repurchased $21 million of its outstanding 11.00% Senior Secured Second Lien Notes due in 2025. As part of these transactions, $1,723 and $3,149 was included in Loss on Debt Extinguishment on the Consolidated Statements of Income for the three and six months ended June 30, 2018 , respectively.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENT LIABILITIES	COMMITMENTS AND CONTINGENT LIABILITIES: The Company and its former parent entered into a separation and distribution agreement on November 28, 2017 that implemented the legal and structural separation of the Company from its former parent. The separation and distribution agreement also identified the assets of the Coal Business that were transferred to the Company and the liabilities and contracts related to the Coal Business that were assumed by the Company as part of the separation and distribution, and provides post-closing indemnification obligations and procedures between the Company and its former parent relating to the liabilities of the Coal Business that the Company assumed. The Company 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 business. The Company accrues the estimated loss for these lawsuits and claims when the loss is probable and reasonably estimable. The Company’s 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 Company as of June 30, 2019 . It is possible that the aggregate loss in the future with respect to these lawsuits and claims could ultimately be material to the Company’s financial position, results of operations or cash flows; however, such amounts cannot be reasonably estimated. The amount claimed against the Company as of June 30, 2019 is disclosed below when an amount is expressly stated in the lawsuit or claim, which is not often the case. Fitzwater Litigation: Three nonunion retired coal miners have sued Fola Coal Company LLC, Consolidation Coal Company (“CCC”) and CONSOL of Kentucky Inc. (“COK”) (as well as the Company's former parent) in West Virginia Federal Court alleging ERISA violations in the termination of retiree health care benefits. The Plaintiffs contend they relied to their detriment on oral statements and promises of “lifetime health benefits” allegedly made by various members of management during Plaintiffs’ employment and that they were allegedly denied access to Summary Plan Documents that clearly reserved the right to modify or terminate the Retiree Health and Welfare Plan subject to Plaintiffs’ claims. Pursuant to Plaintiffs’ amended complaint filed on April 24, 2017, Plaintiffs request that retiree health benefits be reinstated and seek to represent a class of all nonunion retirees who were associated with AMVEST and COK areas of operation. The Company believes it has a meritorious defense and intends to vigorously defend this suit. Casey Litigation: A class action lawsuit was filed on August 23, 2017 on behalf of two nonunion retired coal miners against CCC, COK, CONSOL Buchanan Mining Co., LLC and Kurt Salvatori in West Virginia Federal Court alleging ERISA violations in the termination of retiree health care benefits. Filed by the same lawyers who filed the Fitzwater litigation, and raising nearly identical claims, the Plaintiffs contend they relied to their detriment on oral promises of “lifetime health benefits” allegedly made by various members of management during Plaintiffs’ employment and that they were not provided with copies of Summary Plan Documents clearly reserving to the Company the right to modify or terminate the Retiree Health and Welfare Plan. Plaintiffs request that retiree health benefits be reinstated for them and their dependents and seek to represent a class of all nonunion retirees of any subsidiary of the Company's former parent that operated or employed individuals in McDowell or Mercer Counties, West Virginia, or Buchanan or Tazewell Counties, Virginia whose retiree welfare benefits were terminated. On December 1, 2017, the trial court judge in Fitzwater signed an order to consolidate Fitzwater with Casey. The Casey complaint was amended on March 1, 2018 to add new plaintiffs, add defendant CONSOL Pennsylvania Coal Company, LLC and eliminate defendant CONSOL Buchanan Mining Co., LLC in an attempt to expand the class of retirees. The Company believes it has a meritorious defense and intends to vigorously defend this suit. Other Matters: Various Company subsidiaries are defendants in certain other legal proceedings arising out of the conduct of the Coal Business prior to the separation and distribution, and the Company is also a defendant in other legal proceedings following the separation and distribution. In the opinion of management, based upon an investigation of these matters and discussion with legal counsel, the ultimate outcome of such other legal proceedings, individually and in the aggregate, is not expected to have a material adverse effect on the Company’s financial position, results of operations or liquidity. As part of the separation and distribution, the Company assumed various financial obligations relating to the Coal Business and agreed to reimburse its former parent for certain financial guarantees relating to the Coal Business that its former parent retained following the separation and distribution. Employee-related financial guarantees have primarily been provided to support the United Mine Workers’ of America’s 1992 Benefit Plan and federal black lung and various state workers’ compensation self-insurance programs. Environmental financial guarantees have primarily been provided to support various performance bonds related to reclamation and other environmental issues. Coal and other financial guarantees have primarily been provided to support various sales contracts. 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. The following is a summary, as of June 30, 2019 , of the financial guarantees, unconditional purchase obligations and letters of credit to certain third parties. These amounts represent the maximum potential of total future payments that the Company could be required to make under these instruments, or under the separation and distribution agreement to the extent retained by the Company's former parent on behalf of the Coal 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 in the financial statements. The Company’s management believes that these guarantees will expire without being funded, and therefore, the commitments will not have a material adverse effect on the Company’s financial condition. Amount of Commitment Expiration Per Period Total Amounts Committed Less Than 1 Year 1-3 Years 3-5 Years Beyond 5 Years Letters of Credit: Employee-Related $ 65,292 $ 46,623 $ 18,669 $ — $ — Environmental 398 398 — — — Other 30,411 27,357 3,054 — — Total Letters of Credit 96,101 74,378 21,723 — — Surety Bonds: Employee-Related 90,033 90,033 — — — Environmental 531,959 528,265 3,694 — — Other 3,735 3,248 487 — — Total Surety Bonds 625,727 621,546 4,181 — — Guarantees: Other 19,768 7,664 11,225 398 481 Total Guarantees 19,768 7,664 11,225 398 481 Total Commitments $ 741,596 $ 703,588 $ 37,129 $ 398 $ 481 Included in the above table are commitments and guarantees entered into in conjunction with the sale of Consolidation Coal Company and certain of its subsidiaries, which contain all five of its longwall coal mines in West Virginia and its river operations, to a third party. As part of the separation and distribution, the Company's former parent agreed to indemnify the Company and the Company agreed to indemnify its former parent in each case with respect to guarantees of certain equipment lease obligations that were assumed by the third party. In the event that the third party would default on the obligations defined in the agreements, the Company would be required to perform under the guarantees. If the Company would be required to perform, the stock purchase agreement provides various recourse actions. As of June 30, 2019 , the Company has not been required to perform under these guarantees. The equipment lease obligations are collateralized by the underlying assets. The current maximum estimated exposure under these guarantees as of June 30, 2019 and December 31, 2018 is believed to be approximately $24,000 and $28,000 , respectively. At June 30, 2019 and December 31, 2018 , the fair value of these guarantees was $612 and $734 , respectively, and is included in Other Accrued Liabilities on the Consolidated Balance Sheets. The fair value of certain of the guarantees was determined using the Company’s risk-adjusted interest rate. Significant increases or decreases in the risk-adjusted interest rates may result in a significantly higher or lower fair value measurement. No other amounts related to financial guarantees and letters of credit are recorded as liabilities in the financial statements. Significant judgment is required in determining the fair value of these guarantees. The guarantees of the leases are classified within Level 3 of the fair value hierarchy.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES: The Company enters into interest rate swaps in order to achieve a mix of fixed and variable rate debt that it deems appropriate. The interest rate swaps have been designated as cash flow hedges of future variable interest payments, which are considered probable of occurring. Based on the Company's assessment, all of the critical terms of each of the hedges matched the underlying terms of the hedged debt and related forecasted interest payments, and as such, these hedges were considered highly effective. There is no ineffective portion or amount excluded from effectiveness testing. The following table presents information related to interest rate contracts entered into by the Company and designated as cash flow hedges: June 30, 2019 December 31, 2018 Pay fixed swaps - notional amount $ 200,000 — Net unrealized loss $ (264 ) — Weighted-average maturity period (years) 1.54 — Weighted-average received rate — — Weighted-average pay rate — — The fair value of the interest rate swaps reflected an unrealized loss of $ 264 (net of $ (84) tax) at June 30, 2019 and $0 at December 31, 2018 . The unrealized loss is included on the Consolidated Statements of Stockholders' Equity as part of accumulated other comprehensive (loss) income as well as on the Consolidated Statements of Comprehensive Income as unrealized loss on cash flow hedges. At June 30, 2019 and December 31, 2018 , the interest rate swap contracts were reflected in the Consolidated Balance Sheets as follows: June 30, 2019 December 31, 2018 Current assets: Other current assets — — Long-term assets: Other assets — — Current liabilities: Other current liabilities $ 170 — Long-term liabilities: Other liabilities $ 178 — Total derivatives $ 348 $ — No gains or losses were recognized in interest expense in the Consolidated Statements of Income, as no interest rate swaps have reached their effective date. During 2020, notional amounts of $ 100,000 will become effective. In the next 12 months, the Company expects a loss of approximately $ (46)

FAIR VALUE OF FINANCIAL INSTRUM

FAIR VALUE OF FINANCIAL INSTRUMENTS	6 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS: CONSOL Energy 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 Company’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 Company’s third party guarantees are the credit risk of the third party and the third party surety bond markets. A significant increase or decrease in these values, in isolation, would have a directionally similar effect resulting in higher or lower fair value measurement of the Company’s Level 3 guarantees. 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 financial instruments measured at fair value on a recurring basis are summarized below: Fair Value Measurements at Fair Value Measurements at Description Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Lease Guarantees $ — $ — $ (612 ) $ — $ — $ (734 ) Derivatives (1) $ — $ (348 ) $ — $ — $ — $ — (1) Interest rate swaps are valued based on observable market swap rates and are classified within Level 2 of 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: June 30, 2019 December 31, 2018 Carrying Amount Fair Value Carrying Amount Fair Value Long-Term Debt $ 729,333 $ 754,785 $ 842,899 $ 881,711 Certain of the Company’s debt is actively traded on a public market and, as a result, constitutes Level 1 fair value measurements. The portion of the Company’s debt obligations that is not actively traded is valued through reference to the applicable underlying benchmark rate and, as a result, constitutes Level 2 fair value measurements.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS: Transactions with the Company's Former Parent (2017) Transition Services Agreements The Company entered into a transition services agreement and certain other agreements in connection with the separation and distribution agreement with its former parent to cover certain continued corporate services provided by the Company and its former parent to each other following the completion of the separation and distribution. In connection with the separation and distribution, the Company began to set up its own corporate functions, and pursuant to the transition services agreement, the Company's former parent provided various corporate support services, including certain accounting, human resources, information technology, office and building, risk, security, tax and treasury, building security and tax services, as well as certain regulatory compliance services required during the period in which the Company remained a majority-owned subsidiary of its former parent. The charges associated with these services were not material during the three and six months ended June 30, 2019 and 2018 , and are consistent with expenses that the Company's former parent has historically allocated or incurred with respect to such services. The transition services agreement with the Company's former parent expired in February 2019. Former Parent Receivables and Payables The Company had a receivable from its former parent of $6,540 and $11,788 , of which $6,540 and $5,500 was recorded in Other Receivables on the Consolidated Balance Sheets at June 30, 2019 and December 31, 2018 , respectively. Additionally, $6,288 was included in Other Assets on the Consolidated Balance Sheet at December 31, 2018 . These items relate to the reimbursement of the one-time transaction costs as well as other reimbursements per the terms of the separation and distribution agreement. During the year ended December 31, 2018 , the Company paid its former parent $18,234 related to the final settlement of shared, spin-related fees. Per the separation and distribution agreement, these costs were split equally by the two companies. These costs consisted of consulting and professional fees associated with preparing for and executing the separation and distribution, as well as various other items. CONSOL Coal Resources LP CONSOL Energy, certain of its subsidiaries and the Partnership are party to an Omnibus Agreement, dated September 30, 2016, as amended on November 28, 2017 (the “Omnibus Agreement”). Under the Omnibus Agreement, CONSOL Energy provides the Partnership with certain services in exchange for payments by the Partnership for those services. On November 28, 2017, the Company entered into an Affiliated Company Credit Agreement with the Partnership and certain of its subsidiaries (the Partnership Credit Parties) under which the Company provides as lender a revolving credit facility in an aggregate principal amount of up to $275 million to the Partnership Credit Parties. In connection with the completion of the separation, the Partnership drew an initial $201 million , the net proceeds of which were used to repay outstanding amounts under CCR's $400 million senior secured revolving credit facility with certain lenders and PNC Bank, National Association (“PNC”), as administrative agent (the “Original CCR Credit Facility”), and to provide working capital for the Partnership following the separation and for other general corporate purposes. The Original CCR Credit Facility was then terminated. On March 28, 2019, the Affiliated Company Credit Agreement was amended to extend the maturity date from February 27, 2023 to December 28, 2024. Interest accrues at a rate ranging from 3.75% to 4.75% , subject to the Partnership's net leverage ratio. For the three months ended June 30, 2019 and 2018 , $1,971 and $1,976 of interest expense is included in the Consolidated Statements of Income, respectively. For the six months ended June 30, 2019 and 2018 , $3,766 and $4,110 of interest expense is included in the Consolidated Statements of Income, respectively. The collateral obligations under the Affiliated Company Credit Agreement generally mirror the Original CCR Credit Facility, as does the list of entities that will act as guarantors thereunder. The Affiliated Company Credit Agreement is subject to financial covenants relating to a maximum first lien gross leverage ratio and a maximum total net leverage ratio, which will be calculated on a consolidated basis for the Partnership and its restricted subsidiaries at the end of each fiscal quarter. The Partnership was in compliance with each of these financial covenants at June 30, 2019 . The Affiliated Company Credit Agreement also contains a number of customary affirmative covenants and negative covenants, including limitations on the ability of the Partnership to incur additional indebtedness, grant liens, and make investments, acquisitions, dispositions, restricted payments, and prepayments of junior indebtedness (subject to certain limited exceptions). CCR is a party to a number of other agreements with CONSOL Energy, or its subsidiaries, that are described in detail in the section titled “Agreements with Affiliates” in Item 13 of CCR’s Form 10-K filed on February 8, 2019. Charges for services from the Company to CCR include the following: For the Three Months Ended June 30, For the Six Months Ended June 30, 2019 2018 2019 2018 Operating and Other Costs $ 767 $ 761 $ 1,530 $ 1,447 Selling, General and Administrative Costs 1,974 1,953 5,030 3,598 Total Services from CONSOL Energy $ 2,741 $ 2,714 $ 6,560 $ 5,045 Operating and Other Costs include pension service costs and insurance expenses. Selling, General and Administrative Costs include charges for incentive compensation, an annual administrative support fee and reimbursement for the provision of certain management and operating services provided by the Company. At June 30, 2019 and December 31, 2018 , CCR had a net payable to the Company in the amount of $ 380 and $ 3,831 , respectively. This payable includes reimbursements for business expenses, executive fees, stock-based compensation and other items under the Omnibus Agreement. In May 2019, CONSOL Energy Inc.'s Board of Directors approved an expansion of the stock, unit and debt repurchase program (see Note 19 - Stock, Unit and Debt Repurchase). The program expansion allows the Company to use up to $50 million of the program to purchase CONSOL Coal Resources LP's outstanding common units in the open market. During the six months ended June 30, 2019 , 6,884 of the Partnership's common units were purchased under this program at an average price of $17.35

Equity [Abstract]
STOCK, UNIT AND DEBT REPURCHASE	STOCK, UNIT AND DEBT REPURCHASE: In December 2017, CONSOL Energy’s Board of Directors approved a program to repurchase, from time to time, the Company’s outstanding shares of common stock or its 11.00% Senior Secured Second Lien Notes due 2025, in an aggregate amount of up to $50 million through the period ending June 30, 2019. The program was subsequently amended by CONSOL Energy’s Board of Directors in July 2018 to allow up to $100 million of repurchases of the Company’s common stock or its 11.00% Senior Secured Second Lien Notes due 2025, subject to certain limitations in the Company’s current credit agreement and the tax matters agreement (TMA). The Company’s Board of Directors also authorized the Company to use up to $25 million of the program to purchase CONSOL Coal Resources LP’s outstanding common units in the open market. In May 2019, CONSOL Energy's Board of Directors approved an expansion of the stock, unit and debt repurchase program. The aggregate amount of the program's expansion was $75 million , bringing the aggregate limit of the Company's stock, unit and debt repurchase program to $175 million . The May 2019 expansion also increased the aggregate limit of the amount of CONSOL Coal Resources LP's common units that can be purchased under the program to $50 million , which is consistent with the Company's credit facility covenants that prohibit the Company from using more than $50 million for the purchase of CONSOL Coal Resources LP's outstanding common units. The Company's Board of Directors also approved extending the termination date of the program, from June 30, 2019 to June 30, 2020. Under the terms of the program, CONSOL Energy is permitted to make repurchases in the open market, in privately negotiated transactions, accelerated repurchase programs or in structured share repurchase programs. CONSOL Energy is also authorized to enter into one or more 10b5-1 plans with respect to any of the repurchases. Any repurchases of common stock, notes or units are to be funded from available cash on hand or short-term borrowings. The program does not obligate CONSOL Energy to acquire any particular amount of its common stock, notes or units, and can be modified or suspended at any time at the Company’s discretion. The program is conducted in compliance with applicable legal requirements and within the limits imposed by any credit agreement, receivables purchase agreement, indenture, or the TMA, and is subject to market conditions and other factors. During the six months ended June 30, 2019 , the Company repurchased approximately $19,320 of its 11.00% Senior Secured Second Lien Notes due 2025. Also during the six months ended June 30, 2019 , 351,443 shares of the Company's common stock were repurchased and retired at an average price of $ 27.18 per share, and 6,884 of the Partnership's common units were purchased at an average price of $ 17.35 per unit. During the six months ended June 30, 2018 , the Company repurchased approximately $20,524 of its 11.00% Senior Secured Second Lien Notes due 2025. Also during the six months ended June 30, 2018 , 91,000 shares of the Company's common stock were repurchased and retired at an average price of $36.05 per share. No common Partnership units were purchased under this program during the six months ended June 30, 2018

BASIS OF PRESENTATION (Policies

BASIS OF PRESENTATION (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles 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 accounting principles generally accepted in the United States (“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. Operating results for the three and six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for future periods. The Consolidated Balance Sheet at December 31, 2018 has been derived from the Audited Consolidated Financial Statements at that date but does not include all disclosures required by GAAP. This Form 10-Q report should be read in conjunction with CONSOL Energy Inc.'s Annual Report on Form 10-K for the year ended December 31, 2018 .
Basis of Consolidation	Basis of Consolidation The Consolidated Financial Statements include the accounts of CONSOL Energy Inc. and its wholly-owned and majority-owned and/or controlled subsidiaries. The portion of these entities that is not owned by the Company is presented as non-controlling interest. All significant intercompany transactions and accounts have been eliminated in consolidation.
Recent Accounting Pronouncements	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 costs 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 Company’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 Company’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 Company’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 Update 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. In May 2019, the FASB updated Topic 326 by issuing ASU 2019-05, Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief, which provides entities that have certain instruments within the scope of Subtopic 326-20, Financial Instruments-Credit Losses - Measured at Amortized Cost, with an option to irrevocably elect the fair value option in Subtopic 825-10, Financial Instruments-Overall, applied on an instrument-by-instrument basis for eligible instruments, upon adoption of Topic 326. The amendments in these Updates 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 Company's financial statements.
Earnings per Share	Earnings per Share Basic earnings per share are computed by dividing net income attributable to CONSOL Energy Inc. shareholders by the weighted average shares outstanding during the reporting period. Dilutive earnings per share are computed similarly to basic earnings per share, except that the weighted average shares outstanding are increased to include additional shares from restricted stock units and performance share units, if dilutive. The number of additional shares is calculated by assuming that outstanding restricted stock units and performance share units were released, and that the proceeds from such activities were used to acquire shares of common stock at the average market price during the reporting period.
Reclassifications	Reclassifications Certain amounts in prior periods have been reclassified to conform with the report classifications of the current period, including the reclassification of restricted cash, previously included in Prepaid Expenses and Other Assets on the Consolidated Balance Sheets, as well as the reclassification of amortization of debt issuance costs and loss on debt extinguishment within the Operating Activities section of the Consolidated Statements of Cash Flows. These reclassifications had no effect on previously reported total assets, net income or stockholders' equity.
Revenue Recognition	CONSOL Energy's coal revenue is recognized when title passes to the customer. The Company has determined that each ton of coal represents a separate and distinct performance obligation. The Company's 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 the Company's contracts is based on the total amount of consideration to which the Company expects 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 the Company's performance obligations based on relative stand-alone selling prices determined at contract inception. Coal Revenue Revenues are recognized at a point in time, which is generally 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. The Company's 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 Company’s coal contracts allow for retroactive adjustments to pricing after title to the coal has passed. Some of the Company's contracts span multiple years and have annual pricing modifications, based upon market-driven or inflationary adjustments, where no additional value is exchanged. Also, some of the Company's 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 CONSOL Energy does, from time to time, experience costs of obtaining coal customer contracts with amortization periods greater than one year, those costs are immaterial to the Company's net income. At June 30, 2019 and December 31, 2018 , the Company did not have any capitalized costs to obtain customer contracts on its Consolidated Balance Sheets. As of and for the three and six months ended June 30, 2019 and 2018 , the Company has not recognized any amortization of previously existing capitalized costs of obtaining customer contracts. Further, the Company has not recognized any revenue in the current period that is not a result of current period performance. Terminal Revenue Terminal revenues are attributable to the Company's CONSOL Marine Terminal and include revenues earned from providing receipt and unloading of coal from rail cars, transporting coal from the receipt point to temporary storage or stockpile facilities located at the Terminal, stockpiling, blending, weighing, sampling, redelivery, and loading of coal onto vessels. Revenues for these services are generally earned on a rateable basis, and performance obligations are considered fulfilled as the services are performed. CONSOL Marine Terminal does not normally experience material costs of obtaining customer contracts with amortization periods greater than one year. At June 30, 2019 and December 31, 2018 , the Company did not have any capitalized costs to obtain customer contracts on its Consolidated Balance Sheets. As of and for the three and six months ended June 30, 2019 and 2018 , the Company has not recognized any amortization of previously existing capitalized costs of obtaining Terminal customer contracts. Further, the Company has not recognized any revenue in the current period that is not a result of current period performance. Freight Revenue Some of CONSOL Energy's coal contracts require that the Company sell its coal at locations other than its central preparation plant. The cost to transport the Company's coal to the ultimate sales point is passed through to the Company's customers and CONSOL Energy recognizes the freight revenue equal to the transportation costs when title of the coal passes to the customer.
Leases	The Company determines if an arrangement is an operating or finance lease at inception of the applicable lease. For leases where the Company is the lessee, ROU assets represent the Company’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 Company’s leases do not provide an implicit interest rate, the Company 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 Company 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 Company has operating leases for mining and 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 Company’s lease agreements, the rental payments are adjusted periodically to reflect actual charges incurred for inflation and/or changes in other indexes. Many of the Company's 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 the Company's leases contain clauses regarding the general condition of the equipment upon lease termination, they do not contain residual value guarantees.
