The producer confirmed the event to ILN and identified the victim as miner operator Jessie Adkins, 39.
He was performing bolter duties Thursday morning just before noon local time when the fallen coal pinned him against the nearby continuous mining machine.
While a Consol official did not detail the dimensions, sources close to the incident told the Associated Press the fall measured approximately four feet wide by 13ft long and six to 24 inches thick.
No other injuries were reported in the incident, a producer spokesperson said. Federal, state and company officials are all onsite and investigations have commenced.
No other miners were injured.
The Loveridge operation, located in Marion County, produced just over 6 million tons of coal in 2009, when workers logged more than 1.3 million man hours.
During that time, the mine reported 15 non-fatal days lost operator injuries to federal regulators, and two NFDL contractor injuries.
The last fatal operator injury recorded at Loveridge was in 1996, according to MSHA data.
