Eerie Statement from Miner Killed in Blast
At least three fatalities have happened at the mine in the past dozen years.
In 1998, a worker was killed when a support beam collapsed, dumping bags of cement mix and other materials onto the man, according to a report from the MHSA. Federal investigators blamed poor welding and construction.
In 2001, another worker at the mine died after a portion of roof fell in on him, and an electrician died after being electrocuted while repairing a shuttle car there in 2003.
Massey Energy is a publicly traded company based in Richmond, Va., that has 2.2 billion tons.
Massey Energy Company is no stranger to controversy, reports CBS News chief legal correspondent Jan Crawford. It was at the center of a major Supreme Court case in 2008, after its CEO Don Blankenship was sued and then accused of buying a friendly seat on the West Virginia Supreme Court of Appeals.
The U.S. Supreme Court ruled that state supreme court justice Brent Benjamin should have recused himself from an appeal of a $50 million jury verdict against Massey, because Blankenship spent $3 million to get him elected to the state court, Crawford reports.
