HUNTINGTON, Utah — Rescue crews were drilling into solid coal and hammering through concrete walls Monday to get to six miners in a Utah mine that collapsed and trapped the men 1,500 feet below ground. As the search efforts stretched into the night, workers were unable to make significant progress and the initial effort was declared a failure. “They can be in a chamber in there that’s a thousand feet long or they could be dead,” said Robert Murray, chairman of Cleveland-based Murray Energy Corp. “There’s no way of knowing right now.” [via USA TODAY]
