A worker at a Boone County coal preparation plant is being treated at a Charleston hospital after suffering an injury Wednesday morning.
The state Mine Safety Office says the contract worker was replacing screens at Elk Run Coal's prep plant when he was struck in the chest by an unidentified object. He was taken by helicopter to the hospital.
State investigators closed the part of the plant where the accident took place so they could begin an investigation.
The Elk Run Coal Company is a subsidiary of Massey Energy.
