CLARINGTON, Ohio (AP) _ The roof of a coal mine collapsed Friday, killing two miners, a mining company said.

Six other workers were located inside the mine, said Monroe County Sheriff's Deputy Andrea Smith. An undetermined number were injured and were being treated by rescue teams.

Eight people were working underground when the roof collapsed about 2 p.m., but not all were near the site of the accident, said Tom Hoffman, a vice president for Consol Energy in Pittsburgh, the parent company of Consolidation Coal Co.

``We're talking about a very small portion that was involved,'' he said.

Consol stopped mining coal in March, but has had small crew on duty since then to ship the remaining inventory and to close the mine.

Thirty-four people work at the mine, which was established in 1971.

Clarington is in southeast Ohio, about 22 miles south of Wheeling, W.V.
