A Pennsylvania Department of Environmental Protection spokesperson told the Pittsburgh Tribune-Review that a contractor was crushed below the waist at around 3.30am on Monday.

Contractor GMS said the man suffered a fractured pelvis and was taken to Ruby Memorial Hospital in Morgantown for surgery, where he was in a stable condition.

Consol announced on Monday that the Bailey preparation plant had “resumed normal coal operations” – two weeks after a conveyor belt failure caused a temporary halt.

On August 1 Consol said a partial structural failure at a surface clean coal conveyor belt at the Bailey preparation facility in Greene County, Pennsylvania, caused the company to stop longwall production in the mines.

The belt system at the complex carries coal from the two mines to the clean coal silos at Bailey’s train load-out.

Both mines’ longwalls were completely idled, though all continuous miner units remained operating normally.

“Consol Energy has conducted a thorough assessment of the occurrence and reconstruction of the affected systems got underway on July 30,” officials said at the time, though the date of the failure was not disclosed.

The cost of the repairs has not been reported.

Both Enlow Fork and Bailey, which extract steam coal from the prolific Pittsburgh 8 seam, consistently rank among the top producing mines in the US.

Enlow Fork totaled 8 million tons of output last year while Bailey produced 8.6Mt.

Consol also reaffirmed its guidance to sell between 13.4Mt and 13.9Mt of coal during the third quarter.
