An official with an eastern Kentucky coal mining company has pleaded guilty to federal charges that he put miners at risk. Manalapan Mining Company shift foreman Bryant Massingale acknowledged Thursday that he failed to note hazardous conditions in inspection reports, as required, and failed to correct hazardous conditions. Massingale worked at the company's P-1 mine in Pathfork in Harlan County. A grand jury charged the company and three officials with exposing miners to the risk of injury or death by violating safety rules in June 2011. The company and two other officials have pleaded not guilty. A few weeks before the alleged acts listed in the indictment, 49-year-old David Partin of Pineville, died when a section of the mine wall fell on him.
