'No sign' of trapped miners in Utah

Rescuers found no signs of life after drilling a fourth hole into a collapsed mine in the US where six workers have been trapped for nearly two weeks.

Three people have already died in the rescue effort.

A microphone lowered into the new hole yesterday revealed nothing to indicate that anyone was in the cavern, and attempts to communicate with the miners by tapping on a drill yielded no response, a federal official said.

A video camera was being lowered into the hole overnight.

Underground tunnelling had been halted after a mountain “bump” on Thursday killed three rescuers and injured six others.

Officials had hoped a fourth hole drilled into the mine in Utah would finally offer clues to whether the men were alive 1,500 feet below ground. Instead, the results were the same as the three previous tries.

“We did not detect any signals from miners underground,” said Richard Stickler, head of the federal Mine Safety and Health Administration.

Crews spent at least four hours beating on the drill steel and setting off explosives to try to get the miners’ attention, he said.

Stickler said a fifth hole was planned.

“As long as we have hope, we will continue working and doing everything we can. Our goal is to find these miners alive,” he said.

Rob Moore, vice president of Murray Energy Corp, co-owner of the Crandall Canyon mine, remained optimistic.

“Make no mistake about it: this continues to be a rescue effort,” Moore said. “We have encountered setbacks. We’ve incurred losses, but we have not and will not give up hope.”

Even if rescuers find signs of life – an increasingly unlikely prospect, given the amount of time elapsed – it would take weeks to lift them out.

Crews would have to drill a much larger, 30-inch hole and lower a metal rescue capsule, the same method used in 2002 to pluck nine trapped miners from the flooded Quecreek mine in western Pennsylvania.

But there are key differences between Quecreek and Crandall Canyon that would make the effort far more complicated.

The Utah miners are much further underground and have been trapped much longer than those in the Pennsylvania accident.
