ROCK SPRINGS, Wyo. — The federal Mine Safety and Health Administration is investigating the death of a worker at a southwestern Wyoming coal mine.
Representatives for the Bridger Coal Company and Rocky Mountain Power say Jaime Olivas was hit when a slab of coal suddenly came loose and fell from one of the walls in the underground mine Thursday afternoon.
Olivas, a mining equipment operator, was conscious and speaking when he was brought out of the mine but died on the way to a hospital in Rock Springs.
