Two workers were found dead Saturday, after an underground fire at a mine in Melville, W. Va. This comes just weeks after 12 miners died at another West Virginia mine. Congressional hearings begin Monday into the Sago mine disaster in West Virginia three weeks ago that left 12 miners dead and one recovering in hospital.
The mine's operator was cited for numerous safety violations. Lawmakers want to know what happened — and whether the tragedy could have been averted.
Federal investigators entered the Sago mine this weekend for the first time since the Jan. 2 accident, but they have not yet made it into the deepest part of the mine to investigate what caused the explosion. Federal documents suggest that the Sago mine has a record of committing serious safety violations.
