ANKARA, Turkey — Hope for the survival of 30 trapped Turkish miners were fading Tuesday as rescue workers struggled to reach them a day after a methane gas explosion collapsed parts of a major coal mine in northern Turkey, an engineer said.
The explosion at the Karadon mine near the Black Sea port of Zonguldak buried the miners nearly 540 meters below the surface Monday afternoon.
Rescuers pumped air into the mine to try to dispel the gas and began digging through a collapsed chamber Tuesday to reach the miners, Chief Turkish Engineer Husnu Unal said.
"Their chance of staying alive is decreasing," Unal said, adding the explosion might have been triggered by the use of dynamite during the digging in the mine. Eleven miners survived the blast.
