 "The story of Upper Big Branch is a cautionary tale of hubris. A company that was a towering presence in the coal fields operated its mines in a profoundly reckless manner, and 29 coal miners paid with their lives for the corporate risk taking," the report read. "The company's ventilation system didnot adequately ventilate the mine. As a result, explosive gases were allowed to build up. " The report detailed claims Massey threatened miners with termination if they stopped work in areas that lacked adequate oxygen levels and listed numerous other state and federal safety standards that Massey failed to follow. Also blamed in the report was MSHA for failing to enforce federal regulations.
