Item 8.01                   Other Events.

On July 21, 2010, the Dodd-Frank Wall Street and Consumer Protection Act (the “Dodd-Frank Act”) was enacted into federal law. Section 1503(b)(1) of the Dodd-Frank Act requires a reporting company operating coal mines or with subsidiaries that operate coal mines to file a Current Report on Form 8-K upon receipt of written notice from the Mine Safety and Health Administration (“MSHA”) of an imminent danger order under Section 107(a) of the Federal Mine Safety and Health Act of 1977 (“Mine Act”).

On March 13, 2014 at approximately 11:15 am local time, Hopedale Mining LLC, a wholly owned subsidiary of Rhino Resource Partners LP, received an imminent danger order under Section 107(a) of the Mine Act with respect to methane gas levels in excess of 5.0% in an elevated section at a conveyer belt entry area of its Hopedale mine, located in Hopedale, Ohio, and also in a cavity above a previous roof fall area of the Hopedale mine. Both areas were being ventilated with vent pipe at the time of the imminent danger order.

Personnel at the mine immediately removed power from the area and began corrective actions, which included hanging temporary check curtains and ordering supplies to install permanent ventilation controls for continued ventilation. The corrective actions reduced the methane levels in the affected areas and the conditions in the citation were abated by Hopedale Mining LLC. No employees were injured as a result of the cited violation.
