MONTCOAL, W.Va. (AP) - It could be evening before rescue teams resume a search for four workers missing in a West Virginia coal mine where a massive explosion killed 25 people.
They have to wait until bore holes can be drilled so toxic gases can be ventilated from the area where the miners may be. Officials say the chances for survival are slim.
Gov. Joe Manchin says he is hoping for a miracle that the four missing miners will be found alive.
The four had not been located before dangerous levels of methane gas forced rescue crews out of the mine.
The cause of yesterday's blast isn't known but safety officials say the operation has a history of violations for not properly ventilating highly combustible methane gas.
President Barack Obama is offering his condolences.
