CASPER, Wyo. (AP) — Federal mining regulators gave a southwestern Wyoming coal mine more than two dozen safety violations this week, ranging from the lack of an updated mine map to hydrants with low water pressure.

Operators of the Jim Bridger Coal Mine east of Rock Springs have vowed to fight at least some of the charges. The U.S. Department of Labor's Mine Safety and Health Administration says the mine has stopped production while safety changes are made.

The Associated Press reports that the violations stem from an August inspection. Other safety allegations included an escape line dangling too high for all workers to reach and a segment of roof that wasn't properly supported

PacifiCorp, the mine's majority owner, says it will challenge the MSHA over some of its findings.
