4 missing W. Virginia miners found dead

Rescue crews at a West Virginia coal mine have found no more survivors, and all 29 workers trapped in an explosion areconfirmed dead, officials said early Saturday.

Families, colleagues and officials had been holding out hope that four unaccounted for miners might be found alive inside one of the mine's safety chambers, but rescuers whochecked those sheltersFriday found neitherhad been activated, state Gov. Joe Manchin confirmed at a briefing.

"None of the chambers had been deployed, and none of our miners suffered, so this journey has ended, and now the healing has started," Manchin said.

"We made sure that we have a total count for every miner that was in that mine. The bodies of our miners were found."

In the immediate aftermath of Monday's explosionat theUpper Big Branch-South mine,it was known that 25 workers had died, while the status of the other four was unknown. Rescuers spent the nextfive days attempting to get underground to search for the men, hoping that they had taken refuge inone of the survival chambers.

The firsttworescue attempts were aborted when crews encountered dangerously high levels of carbon dioxide and explosive methane in the mine. Workers spent several days drilling vent holes underground to release the gases.

Crews re-entered the mine, about 50 kilometres south of Charleston, W. Va., around 1 a.m. ET Friday. They were able to check oneairtight chamber for survivors, but the chamber was empty.

The crews moved througha shaftto try to reachasecond chamber, but they were forced to retreat when theysaw smoke and signs of a fire somewhere in the mine.

When they reached the second chamber late Friday night, theydiscovered it, too, had not been activated.

The bodies of the four missing miners were found "exactly where we thought" they might be, Manchin said.

Safety officials investigate

U.S. President Barack Obama hasasked federal mine safety officials to report next week on what caused the deadly blast.

The mine isoperated by Performance Coal Co., a subsidiary of Virginia-based Massey Energy Co., the fourth-largest coal mining company in the United States. Over the past year, Massey Energywas fined $329,000 US forseveral serious violations involving its ventilation plan and equipment at the Upper Big Branch Mine.

Onthe day of the blast, the Mine Safety and Health Administration cited the mine for two safety violations: one involving inadequate maps of escape routes, the other concerning an improper splice of electrical cable. However, Stricklin saidthose violations had nothing to do with the explosion.

On Thursday, Massey CEODon Blankenship continued to defend his company's record and disputed accusations from miners that he puts coal profits ahead of safety.

But in an interview last June for the web series Focus Washington that surfaced this week, Blankenship said that "so many of the laws" on mine safety are "nonsensical from an engineering or coal mining perspective."

"A lot of the politicians, they get emotional, as does the public, about the most recent accident, and it's easy to get laws on the books," he continued.

Blankenship's stance provoked a firm rebuke from Cecil Roberts, president of the United Mine Workers of America union, which doesn't represent any employees at the Upper Big Branch Mine.

"I've seen where Massey's CEO, Don Blankenship, equates criticizing his or Massey's safety record to being against coal and coal jobs," Roberts said in a statement. "I'm here to tell Don that's bull."

Roberts added that his union has tallied 45 deaths not including the four miners whose bodieswereonly found Saturday at Massey-owned mines in the last 11 years.

"No other coal operator even comes close to that fatality rate during that time frame," Roberts said. "That demands a serious and immediate investigation by MSHA and by Congress."
