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 six months ended June 30, 2015 are not necessarily indicative of the results to be expected for future quarters or for the year ending December 31, 2015. To maintain consistency and comparability, certain 2014 amounts have been reclassified to conform to the 2015 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 2014 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 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. We own a 40% equity interest in Savoy Energy, L.P., a private oil and gas company, which has operations in Michigan and a 50% interest in Sunrise Energy, LLC, a private entity engaged in shale and coalbed methane operations in the same vicinity as the Carlisle Mine.

Bank Debt

Bank Debt	6 Months Ended

Bank Debt [Abstract]
Bank Debt	(2) Bank Debt To finance the Vectren Fuels acquisition, we entered into a credit agreement with PNC Bank as administrative agent for a group of several other banks. The credit agreement allows for a $250 million revolver and a $175 million term loan. Our debt at June 30, 2015 was $278 million (term- $153 , revolver- $125) . The maximum that we could borrow at June 30, 2015 was $303 million due to the covenants. The credit facility is collateralized by substantially all of Sunrise’s assets and we are the guarantor. Bank fees and other costs incurred in connection with this new facility were about $6.8 million, which were deferred and are being amortized over five years. All borrowings under the credit agreement bear interest at LIBOR (19 bps at June 30, 2015) plus 2.25% if the leverage ratio (debt/EBITDA) is less than 1X; LIBOR plus 2.5% if the leverage ratio is over 1X but less than 1.5X; LIBOR plus 2.75% if the ratio is over 1.5X but less than 2X; LIBOR plus 3% if the ratio is over 2X but less than 2.5X and at LIBOR plus 3.5% if the leverage ratio is over 2.5X. The computed ratio at June 30, 2015 was 2.76X . The maximum leverage ratio is currently 3.00 X. We entered into swap agreements to fix the LIBOR component of the interest rate to achieve an effective fixed rate of no greater than 5% on 100% ($175 million) of the term loan and on $100 million of the revolver. The revolver swaps step down 10% each quarter commencing March 31, 2016 . At June 30, 2015, these two interest rate swaps had an estimated net fair value liability of $1.266 million consisting of a long-term asset of $.812 million and a current liability of $2.078 million. Such amounts are included in other long-term assets and accounts payable and accrued liabilities, respectively. The credit agreement also imposes certain other customary restrictions and covenants as well as certain milestones we must meet in order to draw down the full amount. Any non-tax cash distributions from Savoy are required to be applied toward the debt. The term loan requires quarterly payments with annual amortization at 10% , 15% , 15% , 20% , and 20% with a balloon at maturity. The credit agreement matures on August 29, 2019 , but we have the right to prepay the loan at any time without penalty.

Net Income per Share	(7) Net Income per Share We compute net income per share using the two-class method, which is an allocation formula that determines net income per share for common stock and participating securities, which for us are our outstanding RSUs . Outstanding RSUs have been excluded from the calculation of diluted weighted average shares outstanding because the impact would be anti-dilutive. The following table sets forth the computation of net income per share for the six and three months ended June 30, 2015 and 2014 (in thousands): Six Months Ended June 30, Three Months Ended June 30, 2015 2014 2015 2014 Numerator: Net income $ $ $ $ Less earnings allocated to RSUs Net income allocated to common shareholders $ $ $ $

Asset Realization [Abstract]
Asset Realization	( 9) Asset Realization The Carlisle assets had an aggregate carrying value of $181 million at June 30, 2015. Considering the modifications to our coal contracts and the reduction in force as discussed in the MD&A section, we conducted review of those assets for recoverability, and determined that no impairment charge was necessary. In conducting such review, we assumed (i) that natural gas prices will start to increase in late 2016 (ii) Carlisle production will increase in 2017 and (iii) sometime in 2019, the Carlisle Mine will return to its normal production capacity of three million tons per year. If , in later quarters , we change our estimates for downward revisions to the future net cash flows attributable to the Carlisle Mine, this may result in future impairment of such assets and such charges could be significant.
