Fatal Mine Collapse Covered 50 Acres ScienceDaily (Jun. 3, 2008) — New calculations show that the deadly Crandall Canyon mine collapse -- which registered as a magnitude-3.9 earthquake -- began near where miners were excavating coal and quickly grew to a 50-acre cave-in, University of Utah seismologists say in a report on the tragedy. The University of Utah Seismograph Stations estimated the size of the collapse is about four times larger than was thought shortly after the time of the Aug. 6, 2007, disaster that resulted in the deaths of six miners and, 10 days later, three rescuers. The seismologists'...

HUNTINGTON, Utah - The latest holed drilled into a collapsed mine where six men are trapped broke through a chamber too small for the men to survive, a lawyer for several of the men's families said Saturday.

As rescuers drilled a final hole into a Utah mountain Thursday to search for six missing coal miners, the U.S. Senate added its voice to a growing chorus of questions raised over the safety of the mine. The Senate Appropriations subcommittee that oversees labor issues announced plans for a hearing on the mine collapse when Congress returns from its summer break Sept. 5. Sen. Edward Kennedy, D-Mass., chairman of the Health, Education, Labor and Pensions Committee, also demanded a list of documents Thursday from the Labor Department about the Crandall Canyon Mine and its operators. Kennedy wants to review several...

HUNTINGTON, Utah — Lashing out at criticism he was abandoning six trapped coal miners, the mine chief promised Wednesday to keep searching through the weekend and punch yet another hole into "this evil mountain." Bob Murray, the face of the rescue effort since the August 6 cave-in, dropped from public view for a time after three men died trying to tunnel toward the miners, but he said he's always been focused on finding the six - dead or alive. "I didn't desert anybody," Murray, the mine's co-owner, told The Associated Press. "I've been living on this mountain every day, living...

This past week, America has watched in anticipation as workers attempt to rescue six trapped miners in a Utah coal mine. Daily news conferences and minute updates have kept us on the edge of our seats, anxious for any sign that the trapped miners are alive. Murray Energy and the Department of Labor’s Mine Safety and Health Administration have deployed over 130 miners to dig into the mine. Without hesitation or question, local mining companies have devoted much of their resources to this rescue mission. No one ever stopped to consider the bottom line. For a moment allow me to...

HUNTINGTON, Utah — Officials extinguished nearly all hope of finding any of the six miners alive on Sunday, nearly two weeks after the men were trapped in a violent collapse deep with a mine. The latest results from a fourth hole drilled more than 1,500 feet into the mountainside found the air quality could not sustain life, said a top executive of the company that co-owns the Crandall Canyon Mine. "It's likely these miners may not be found," said Rob Moore, vice president of Murray Energy Corp.

A national mine safety expert believes the two collapses at the Crandall Canyon Mine [snip] were caused by "bumps" that resulted from the way operations were being conducted at the Huntington mine. Mining bumps are pressure-shifting seismic events than can cause the walls, pillars, ceiling and even the floor of a mine to literally explode and disintegrate. They can cause deaths and injuries, and can result in cave-ins. [snip] And while an investigation ultimately will determine the cause, Ferriter told the Deseret Morning News on Friday he feels certain the bumps were caused by mining activity. "In my opinion, based...

HUNTINGTON, Utah (ABC 4 News) - Equipment used in the Crandall Canyon Mine rescue efforts picked up "significant noise activity" early Wednesday evening. Mine officials say the sound came from the area where a third hole broke through the mine Wednesday. "Don't read too much into this," said mine owner Robert Murray. Mine officials say the noise is not necessarily an indication of life in the mine, but are saying it is a reason to continue hope. Officials expect to get video back from the third hole by 9:00 p.m. Air sample readings are expected around 11:00 Wednesday night. A...

The problem-plagued effort to rescue six miners trapped in a Utah coal mine suffered its most grave setback Thursday night, when a seismic shudder sent rock tumbling onto rescue workers, killing three and injuring six, authorities said. The mountain "bump" occurred about 6:30 p.m., as the group of more than 100 rescue workers continued to carefully tunnel through the collapsed Crandall Canyon Mine. Since Aug. 6, when a predawn cave-in buried the miners, regular seismic tremors have slowed the dig to a virtual crawl. There has been no indication of whether the trapped miners are alive, and officials emphasized that...

HUNTINGTON -- Underground efforts to reach six miners trapped in central Utah's Crandall Canyon mine since Aug. 6 have been suspended indefinitely following a Thursday night cave-in that killed three rescue workers. Richard Stickler, assistant secretary of Labor over the federal Mine Safety and Health Administration, said efforts deep inside the coal mine would remain halted unless some way is found to safely resume them. "This was a tragic accident [that] was the result of seismic activity, a mountain 'bump,'" he said at a late-morning briefing near the mine. "We had put in the strongest ground-support system . . ....
