(CNN) -- A coal miner died Monday morning from injuries sustained in an underground roof collapse at an eastern Pennsylvania mine, state and federal officials said.
The accident happened at about 10:15 a.m. at the Harmony Mine near Mount Carmel, about 90 miles northwest of Philadelphia, said Tom Rathbun, a spokesman for the state Department of Environmental Protection.
No other injuries were reported.
The miner, who was not immediately identified, was trapped deep in a tunnel and partially covered by debris, Rathbun said. Fellow miners pulled him out before he was airlifted to a regional hospital.
An official with the federal Mine Safety and Health Administration said the miner was initially conscious and speaking, but died later.
State and federal inspectors are investigating the accident. The mine is owned by UAE Coal Corp. Associates.
The miner's death is the third coal mine related death in Pennsylvania and the 15th nationwide this year, according to MSHA.
