On the Watch List, our regular series about the people and agencies
charged with overseeing our health and safety, we examine what went wrong at the Upper Big Branch mine in April of this year, when a portion of the mine blew up, killing 29 men. The U.S. government called the explosion “the worst mining disaster in almost 40 years.” The mine is
owned by Massey Energy, the sixth largest mining company in America.
