Fifteen coal mines and four non-coal operations in 10 states received citations for safety violations during the latest round of federal special inspections.
The Mine Safety and Health Administration said Tuesday that its inspectors issued 339 citations during the May inspections to coal mines in Kentucky, West Virginia, Virginia, Pennsylvania, Illinois and Utah. Another 62 citations were issued to non-coal operations in Texas, California, Nevada and Iowa.
The agency started the special inspections after 29 miners died in an explosion at the Upper Big Branch coal mine in southern West Virginia in April 2010.
MSHA says it's issued more than 5,000 citations since the special inspections began.
