The former CEO of Massey Energy Co. goes on trial today in U.S. District Court in Charleston, West Virginia in a case that could set a precedent for corporate higher-ups being held accountable for the safety of their workers.

The Mine Safety and Health Administration today announced that federal inspectors issued 225 citations and six orders during special impact inspections at 15 coal mines and six metal and nonmetal mines in July.

Haulage machinery in underground coal mines – such as shuttle cars, ram cars and scoops – would have to be equipped with technology that prevents miners from becoming struck, pinned or crushed, as per a proposed rule from the Mine Safety and Health Administration.

In the wake of a deadly day in mining in which three miners lost their lives in separate incidents in Nevada, North Dakota and Virginia on Aug. 3, the Mine Safety and Health Administration (MSHA) is stepping up enforcement efforts and intensifying outreach and education nationwide.

In the first six months of 2015, the U.S. Department of Labor’s Mine Safety and Health Administration recorded the deaths of 18 miners in mining industry accidents in its national mid-year summary released today. The toll represents a decrease of five metal and nonmetal deaths from the same period in 2014.
