The Mine Safety and Health Administration issued 214 violations during special inspections at nine coal mines in March. Inspectors closed Redhawk Mining's Redhawk No. 1 in Floyd County, Kentucky for 72 hours and issued 40 violations. MSHA says the mine has a history of releasing methane and was on notice about ventilation, but there was insufficient air flow, and water sprayers that control dust weren't working properly. MSHA also issued 38 citations and 16 unwarrantable failure orders at Perry County Coal's E3-1 Mine. Inspectors found 14 accumulations of explosive material, from paper-thin coatings of coal dust to piles of coal 3 feet thick. MSHA says the hazards had clearly existed for some time. MSHA also issued citations and orders to the Brem Coal Co. LLC No. 2 Mine in Pike County.
