Methane blast traps 30 in Pakistani coal mine

QUETTA, Pakistan - Methane gas sparked an explosion inside a coal mine in Pakistan's southwestern province of Baluchistan, trapping around 30 miners on Sunday, a government official said.
The blast occurred in a mine run by the state-owned Pakistan Mineral Development Corporation (PMDC) in Surran range, some 35 km (22 miles) east of the provincial capital, Quetta.
"We don't know about casualties right now. Rescue workers are busy in their work. Some 30 workers were inside the mine at the time of the blast," a senior PMDC official told Reuters.
