In 2006 , the Sago Mine disaster , an explosion in a coal mine indirectly owned by International Coal Group , likely caused by a lightning strike , led to the deaths of 12 miners . The mine had 12 roof collapses in 2005 , and United States Department of Labor data showed 208 citations for safety violations in that same period , including 21 times for build-up of toxic gases . Miners and their families accused Ross of ignoring safety violations . Ross defended his company 's management of the mine
