A Murray Energy subsidiary has been cited by federal regulators for an accident that killed one worker and injured three others at a mine in Marshall County.
A report released Wednesday by the U.S. Mine Safety and Health Administration says McElroy Coal. Co. didn't adequately support the roof, face and walls where miners work or travel.
The report also attributed the accident to a faulty mining method.
On March 8, 45-year-old John M. Garloch of Neffs, Ohio, died after a piece of coal and rock fell from an exposed area where a longwall machine was extracting coal. Three other workers were injured. The accident occurred at the Marshall County Mine.
Murray Energy told the Charleston Gazette-Mail that it's reviewing the report. The company says safety is its highest priority.
