Inspectors issued 101 citations and two orders during special inspections at six Kentucky surface coal mines last month, according to a news release from the U.S. Mine Safety and Health Administration.
Those enforcement actions were among 253 citations issued at mines nationwide during the February "impact" inspections, MSHA said.
The agency began doing those inspections after the April 2010 explosion at a Massey Energy mine in West Virginia that killed 29 miners.
The goal of the inspections is to focus extra attention on mines with a poor compliance history or other indicators of potential problems, such as a high number of hazard complaints or accidents, the agency said.
Never miss a local story.
In a switch, most of the inspections in February were at surface mines. That was because of recent deaths at surface mines, said MSHA chief Joseph A. Main.
The mines inspected in Kentucky were operated by Frasure Creek Mining; Viking Acquisition Group; Licking River Mining; CDR Operations; and Nally & Hamilton Enterprises, MSHA said.
The mines were in Perry, Pike, Magoffin, Knott and Leslie counties.
