Rescuers injured at Utah mine

HUNTINGTON, Utah, Aug. 16 (UPI) -- At least nine rescue workers were hurt and there may have been another collapse Thursday at a mine where six men have been trapped since Aug. 6, CNN said.

An undetermined number of rescue workers were taken by ambulance from the Crandall Canyon mine. Officials at Castleview Hospital in Price, Utah, told CNN there may have been another collapse.

Bob Murray, president and chief executive officer of mine co-owner Murray Energy Group told CNN: “We are in an emergency situation here.”

Rescue crews earlier Thursday drilled a fourth hole in an effort to reach the six miners trapped under hundreds of feet of rock and coal at a Utah mine.

The hole was moved to head for an area of the mine where geophones had picked up a few minutes of vibrations Wednesday, The Deseret Morning News reported.

The six miners have not been heard from since a collapse of part of the mine Aug. 6. Three holes have found empty caverns.

There was some seismic activity inside the mine, causing a change of pressure.

"The mountain is still alive, and the mountain is not allowing us to advance as rapidly as we would like to," Murray told reporters.

Murray contends that an earthquake caused the collapse, although seismologists say that the collapse itself appears to have been what seismographs picked up.
