Massey Energy Co., which owns the West Virginia coal mine where 29 miners died last week, had 10 coal mines where injury rates topped the national rate last year. Four of the mines — in Tazewell County, Va.; Raleigh County, W.Va.; and Pike County, Ky. — had rates that were more than twice the national rate. The national rate for nonfatal injuries in underground coal mines last year was 4.03 injuries per 200,000 worker hours. Following are injury rates for 35 Massey facilities identified by federal regulators as active, coal-producing underground mines.
