There are no survivors from the Monday explosion at the Upper Big Branch mine in West Virginia.
The death toll marks this as the worst US mine disaster in 4 decades, the New York Times reported.
Seven bodies were removed immediately after the blast, and an effort is underway to ventilate the mine so the other bodies can be recovered, CNN reported.
Officials believe the explosion was caused by a methane buildup, the New York Times reported.
The West Virginia director of homeland security estimated it will take two days to recover the bodies, CNN said.
