Rescue crews go back into mine to look for survivors

MONTCOAL, W.Va. - Searchers desperately hoping to find up to four survivors of a mine blast that killed 25 went back underground early today, while workers above pumped nitrogen into the ground to flush out dangerous gases that have kept rescuers at bay.

The search teams were wearing oxygen masks and carrying four spares on the slim chance the men had made it to airtight emergency rooms and were waiting to be saved more than three days after the nation's deadliest mine disaster in decades.

"We committed to the families we were going to get into the chambers within 96 hours and we're doing everything in our power to do that," said Kevin Stricklin, a coal administrator from the federal Mine Safety and Health Administration.

Air holes drilled into the Upper Big Branch mine have ventilated lethal carbon monoxide, highly explosive hydrogen and methane, which has been blamed for the explosion, but not enough to make the atmosphere safe, so nitrogen tankers were to start pumping.

"I believe the families are relieved that this process has started," Gov. Joe Manchin said.

By the time teams reach the area where the survivors might be, the nitrogen pumping will have started, Stricklin said. They will be wearing breathing gear. Stricklin estimated it should take the teams an hour and a half to reach the search area.

Once methane levels inside the mine have dissipated, the nitrogen will be sucked back out so the air inside the mine will return to normal, Stricklin said.

On Thursday, searchers spent four hours working their way by rail car and on foot through the mine and came within 500 feet of a rescue chamber where possible survivors may be, but turned around when the air became too toxic. When told to abandon their mission, they were angry, but their safety was paramount, said Chris Adkins, chief operating officer for mine owner Massey Energy Co.

Teams were headed first to an airtight chamber that has at least four days worth of food, water and oxygen. Besides finding possible survivors, crews will eventually be recovering the 18 known dead. Seven bodies have been recovered and two miners survived with injuries in the worst coal mine disaster in more than two decades.

Sen. Robert Byrd's office said Thursday that MSHA told the West Virginia Democrat it had ordered the mine evacuated 61 times since the start of 2009, although it was unclear what prompted those or whether they were full or partial evacuations.

Massey's chief executive officer, Don Blankenship, continued to defend his company's record and disputed accusations from miners that he puts coal profits ahead of safety.

"To some extent the fact that there were more survivors than those that are lost suggests that the mine was in pretty good shape relative to what mines would have been in the past and hopefully by today's standards," he told The Associated Press on Thursday. There were 61 miners in Upper Big Branch when it exploded.

Throughout communities surrounding the mine, families and neighbors anxiously watched the slow progress.

Regina Lilly was at Arvon's Floral in Whitesville buying a black and yellow ribbon arrangement to hang on her front door in support of the miners.

"They want answers; they're not getting answers," she said of the families of those missing or dead still inside. "They want their family members brought out of that mine; they haven't got that yet."

Manchin said the families of those still in the mine were being patient.

"These are the strongest, toughest people I've ever seen," he said. "These people can handle about anything you put up."

Adkins said rescue teams described seeing evidence of "a horrendous explosion and a lot of destruction."

He also said they may have found an alternate route that will allow them to get where they need to be faster when they can safely go back in.

Once that happens, rescuers will have to walk through an area officials have described as strewn with bodies, twisted railroad track, shattered concrete block walls and vast amounts of dust. Each team member wears 30 pounds of breathing equipment, lugs first-aid equipment and must try to see through total darkness with only a cap lamp to light the way.

One of the injured miners had been released from Raleigh General Hospital, but his family asked for privacy, said Cathy Boyd, a nursing supervisor. Manchin said the miner was in "total withdrawal" and doesn't want to speak to anyone.

The federal mine agency has appointed a team of investigators, and President Barack Obama said Thursday that he has asked federal mine safety officials to report next week on what may have caused the blast.

The mine is outfitted with air-quality sensors that shut down some of the mining machinery when methane levels reach a high level.

Manchin said it's unclear whether the methane levels reached that point prior to the blast, or whether the sensors detected it. However, the positioning of several bodies in an underground rail car begs the question: "Did a sensor not go off?" the governor said Thursday.

"The miners that they found, it doesn't look like anyone was alarmed or warned that something as this horrific was going to happen," Manchin told The Associated Press.

Even with high gas levels inside the mine, there must have been a source of ignition, Manchin said, and it's unclear what that might have been.

Massey has been repeatedly cited for problems with the system that vents methane and for allowing combustible dust to build up, including two large fines assessed in January when federal inspectors found dirty air flowing into an escapeway where fresh air should be, and an emergency air system flowing in the wrong direction. Miners were so concerned about the conditions that several told their congressman they were afraid to go back into the mine.

Even the day of the blast, the federal mine agency cited the mine for two safety violations, one involving inadequate maps of escape routes, the other concerning an improper splice of electrical cable. Stricklin said, however, that those violations had nothing to do with the explosion.

Blankenship, the Massey CEO, disputes accusations from miners that he puts coal profits ahead of safety.

He told AP that the company would pay funeral expenses for the miners killed. He also said he does not think the company has any information about methane levels in the mine before the explosion.

The Upper Big Branch mine produced more than 1.2 million tons of coal last year and uses the lowest-cost underground mining method, making it more profitable. It produces metallurgical coal that is used to make steel and sells for up to $200 a ton - more than double the price for the type of coal used by power plants.
