Coal production is expected to slow down after a small section of roof collapsed in a Greene County mine.
No one was injured in last weekend’s roof collapse. The collapse was in the Emerald Mine, just south of Waynesburg.
State Department of Environmental Protection spokesman Tom Rathbun says the piece of roof fell on a stage loader, a piece of equipment that moves coal to a conveyor belt.
A spokesman for Foundation Coal Holdings, Rick Nida, says the problem is not unusual. He says the miners could see the problem developing and knew to stay away. The Maryland-based company owns the mine. Nida says the collapse will slow down production.
