General Business [Abstract]
General Business	(1) General Business  The interim financial data is unaudited; however, in our opinion, it includes all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the results for the interim periods. The financial statements included herein have been prepared pursuant to the SEC’s rules and regulations; accordingly, certain information and footnote disclosures normally included in GAAP financial statements have been condensed or omitted.  The results of operations and cash flows for the nine months ended September 30, 2017, are not necessarily indicative of the results to be expected for future quarters or for the year ending December 31, 2017. To maintain consistency and comparability, certain 2016 amounts have been reclassified to conform to the 2017 presentation.  Our organization and business, the accounting policies we follow and other information, are contained in the notes to our consolidated financial statements filed as part of our 2016 Form 10-K. This quarterly report should be read in conjunction with such 10-K.  The consolidated financial statements include the accounts of Hallador Energy Company (the Company) and its wholly-owned subsidiary Sunrise Coal, LLC (Sunrise) and Sunrise’s wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. We are engaged in the production of steam coal from mines located in western Indiana.  New Accounting Standards Issued and Adopted  In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory ("ASU 2015-11"). ASU 2015-11 simplifies the subsequent measurement of inventory. It replaces the current lower of cost or market test with the lower of cost or net realizable value test. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The new standard was applied prospectively and is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted. The adoption of ASU 2015-11 did not have a material impact on our consolidated financial statements.  New Accounting Standards Issued and Not Yet Adopted  In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 is a comprehensive revenue recognition standard that will supersede nearly all existing revenue recognition guidance under current U.S. GAAP and replace it with a principle-based approach for determining revenue recognition. ASU 2014-09 will require that companies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also will require additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for interim and annual periods beginning after December 15, 2017. Early adoption is permitted only in annual reporting periods beginning after December 15, 2016, including interim periods therein. Entities will be able to transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. The Company’s primary source of revenue is from the sale of coal through both short-term and long-term contracts with utility companies whereby revenue is currently recognized when risk of loss has passed to the customer. Upon adoption of this new standard, the Company believes that the timing of revenue recognition related to our coal sales will remain consistent with our current practice. The Company is currently evaluating other revenue streams to determine the potential impact related to the adoption of the standard, as well as potential disclosures required by the standard. Because we do not anticipate a change in our pattern of revenue recognition, we anticipate that neither method of adoption will have a material impact on our consolidated financial statements, other than the additional disclosure requirements which will apply to us .  In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU 2016-02 increases transparency and comparability among organizations by requiring lessees to record right-to-use assets and corresponding lease liabilities on the balance sheet and disclosing key information about lease arrangements. The new guidance will classify leases as either finance or operating (similar to current standard’s “capital” or “operating” classification), with classification affecting the pattern of income recognition in the statement of income. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. We are currently in the process of accumulating all contractual lease arrangements in order to determine the impact on our financial statements and do not believe we have significant amounts of off-balance sheet leases; accordingly, we do not expect the adoption of ASU 2016-02 to have a material impact on our consolidated financial statements. 

Bank Debt

Bank Debt [Abstract]
Bank Debt	(2) Bank Debt  On March 18, 2016, we executed an amendment to our credit agreement with PNC, as administrative agent for our lenders, for the primary purpose of increasing liquidity and maintaining compliance through the maturity of the agreement in August 2019 . The revolver was reduced from $250 million to $200 million, and the term loan remains the same. Our debt at September 30, 2017 , was $211 million (term- $80 million , revolver- $131 million ). As of September 30, 2017 , we had additional borrowing capacity of $69 million and total liquidity of $83 million.  Bank fees and other costs incurred in connection with the initial facility and the amendment were $9.1 million, which were deferred and are being amortized over the term of the loan . The credit facility is collateralized by substantially all of Sunrise’s assets, and we are the guarantor. The amended credit facility increased the M aximum L everage R atio (Sunrise total funded debt/ trailing 12 months adjusted EBITDA) to those listed below:  Fiscal Periods Ending Ratio  September 30, 2017 through March 31, 2018 4.25X  June 30, 2018 and September 30, 2018 4.00X  December 31, 2018 3.75X  March 31, 2019 and June 30, 2019 3.50X  The amended credit facility also requires a D ebt S ervice C overage R atio minimum of 1.25X through the maturity of the credit facility. The amendment defines the D ebt service C overage as Sunrise ’s trailing 12 months adjusted EBITDA/annual debt service.  At September 30, 2017 , our M aximum L everage R atio was 2.42, and our debt service coverage ratio was 2.19. Therefore, we were in compliance with those two ratios.  The interest rate on the facility ranges from LIBOR plus 2.25% to LIBOR plus 4% , depending on our leverage ratio. We entered into swap agreements to fix the LIBOR component of the interest rate to achieve an effective fixed rate of ~5% on the original term loan balance and on $100 million of the revolver. The revolver swap notional value step s down 10% each quarter which commenced on March 31, 2016.  At September 30, 2017 , we were paying LIBOR of 1.24% plus 3.50% for a total interest rate of 4.74% . We anticipate this stepping down to LIBOR plus 3.00% in November, 2017.   Bank debt less debt issuance costs are presented below (in thousands):     September 30, December 31,  2017 2016  Current debt $ 35,000 $ 30,625  Less debt issuance cost (1,829) (1,829)  Net current portion $ 33,171 $ 28,796   Long-term debt $ 175,742 $ 207,992  Less debt issuance cost (1,676) (3,048)  Net long-term portion $ 174,066 $ 204,944

Asset Impairment Review [Abstract]
Asset Impairment Review	 (7 ) Asset Impairment Review Carlisle Mine  In December 2016, the deterioration of the North End of the Carlisle Mine (the North End), coupled with lower coal prices led us to determine that the North End could no longer be mined safely and profitably. The sealing of the North End was completed in March 2017.  With the Carlisle Mine remaining in hot idle status, we conducted a review of the Carlisle Mine assets as of September 30, 2017, based on estimated future net cash flows, and determined that no impairment was necessary.  The Carlisle Mine assets had an aggregate net carrying value of $112 million at September 30, 2017. If in future periods, we reduce our estimate of the future net cash flows attributable to the Carlisle Mine, it may result in future impairment of such assets and such charges could be significant. Bulldog Mine  In October 2017, we entered into an agreement to sell land associated with the Bulldog Mine for $4.9 million. As part of the transaction, we will hold the rights to repurchase the property for 8 years . Because of the likelihood of exercising the repurchase option, we will account for the sale as a financing transaction. The Bulldog Mine assets had an aggregate net carrying value of $15 million at September 30, 2017. Also in October 2017, the Illinois Department of Natural Resources (ILDNR) notified us that our mine application, along with modifications, was acceptable. The permit will be issued upon submittal of a fee and bond which is required to be submitted within 12 months of the notification. We have determined that no impairment is necessary. If estimates inherent in the assessment change, it may result in future impairment of the assets.

Income Taxes [Abstract]
Income Taxes	(8) Income Taxes  Our effective tax rate (ETR) was estimated at 8% and 15% for the nine months ended September 30, 2017 and 2016 , respectively . Assuming no changes in our expected results of operations, we expect our ETR for the remainder of 2017 to be about the same as the first nine months of 2017. Our ETR differs from the statutory rate due primarily to statutory depletion in excess of tax basis, which is a permanent difference.
