Three Mine Workers Killed In Second Collapse

The search for six miners missing deep underground was abruptly halted after a second cave-in killed three rescue workers and injured at least six others who were trying to tunnel through rubble to reach them.

It was a devastating turn for the families of the six men trapped in the Aug. 6 collapse at the Crandall Canyon mine and for the relatives of those trying to rescue them. It's not known if the trapped miners are alive.

"It just feels like a really hard blow to swallow after all we've been through the last week and a half and everyone trying to hope in their own individual way," Huntington Mayor Hilary Gordon said in telephone interview Friday with CNN's "American Morning."

All rescue workers were evacuated from the mine Thursday evening
and work underground was stopped.

The cave-in at 6:39 p.m. was believed to be caused by what seismologists call a "mountain bump," in which shifting ground forces chunks of rock from the walls with great force.

Seismologists say such a bump caused the Aug. 6 cave-in that
trapped the six men more than 3 miles inside the central Utah mine.
That led to the frenetic effort by rescuers to dig through the mine
toward the men and drill narrow holes atop the mountain in an
attempt to learn their whereabouts and perhaps drop down food and
