US Mine Safety and Health Administration spokesman Jesse Lawder told ILN the worker, whose name has not been released, was killed in the 10.35am accident Tuesday after being caught between a power center and the mine rib.

“The accident occurred during the move of a spare longwall power center,” he said.

“The miner was given CPR during transport from underground, but was pronounced dead after being brought to the surface.”

Federal officials were still on scene Wednesday morning and an investigation into the incident’s causes has commenced.

Lawder added that a 103j order was issued Tuesday to close the mine for an accident investigation but it was unclear if the J order was converted to a 103k or if the mine was still closed.

On March 23, shuttlecar operator Harold Ennis, 37, died after being electrocuted by an energized trailing cable.

Shoal Creek is located in Jefferson, Walker and Tuscaloosa counties and is Drummond’s only underground operation in the US.

The company has a surface mining complex, also in Alabama, as well as holdings in Colombia.

The medium-volatile, low-sulfur metallurgical coal-producing Shoal Creek operation is the largest mine in Alabama and one of the largest underground operations in the US.
