Maryland ? Workers found the bodies of two miners in the cabs of heavy machinery Friday, three days after they were buried when a wall section collapsed in an open-pit coal mine.

The men appeared to have died instantly, said Bob Cornett, acting regional director for the federal Mine Safety and Health Administration. Their remains were found beneath at least 45 feet of rocks and dirt in the battered backhoe and bulldozer.

The MSHA identified the bulldozer operator as Mike Wilt, 37, and the backhoe operator as Dale Jones, 52.
