| CRANDALL CANYON MINE Located in Manti-La Sal National Forest, 16 miles (25km) from HuntingtonUses the "retreat mining" method, which experts say is one of most dangerous Coal pillars hold up area of mine's roof. When completely mined, pillars are pulled, causing intentional roof collapse In pictures: Mine rescue Initial readings showed oxygen levels were good, but they were in fact taken from the bore hole and not the mine, said Mr Murray. | CRANDALL CANYON MINE Located in Manti-La Sal National Forest, 16 miles (25km) from HuntingtonUses the "retreat mining" method, which experts say is one of most dangerous Coal pillars hold up area of mine's roof.
