SALT LAKE CITY (AP) -- Murray Energy Corp. and the Mine Safety Health Administration are fighting over another Utah coal mine.
UtahAmerican Energy Inc., a subsidiary of Murray Energy, has asked a federal judge to overturn an MSHA citation requiring the company to change its roof control plan before longwall mining can resume again at the West Ridge mine in Carbon County.
MSHA also says the mining company must keep barrier pillars intact in sections for future mining.
An MSHA spokesman tells The Salt Lake Tribune that the agency wants to make sure there is a plan in place to protect miners from hazards when the coal seam shifts as it is ground away by the longwall mining machine.
Another Murray subsidiary operated Utah's Crandall Canyon mine, where six miners were killed and three rescuers died 10 days later when the mine caved in in August 2007.
