A microphone lowered into a Utah coal mine cavity through a 2.5-inch hole has so far picked up no signs of life from six miners believed to be trapped there. Mine Company CEO Bob Murray cautioned against interpreting the development as bad news. He said the "good news" is that the drill found the cavity. There has been no communication with the miners since Monday.
Tests showed that the air in the chamber was "very, very good," he said. "That means
if they're alive, they're going to stay alive in that atmosphere," Murray said.
The drill pierced the chamber 1,500 feet underground late last night.
