TORONTO (miningweekly.com) – Diversified miner Cliffs Natural Resources on Friday filed a report stating that workers were evacuated from one of its West Virginia coal mines on Monday when high methane levels were detected.

Cliffs filed a ‘Shutdowns and Patterns of Violations’ report with the US Securities and Exchange Commission stating that it had received a 107(a) order related to an elevated methane level along Cliffs subsidiary Pinnacle Mining’s active longwall gob area.

All nonessential personnel were removed from the affected area after the miner received an ‘imminent danger order’ from the federal Mine Safety and Health Administration (MSHA), and production from the longwall was halted.

The miner said the condition was remediated the same day, with the MSHA terminating the order on August 14.

The company’s shares traded at $42.60 apiece on the NYSE on Friday.
