Rescuers go after 13 coal miners nearly 12 hours after explosion

They are believed to be about 2 miles inside the mine.
TALLMANSVILLE, W.Va. (AP) -- A coal mine explosion that may have been sparked by lightning trapped 13 miners 260 feet below ground Monday, and rescuers went in to find them after waiting almost 12 agonizing hours for dangerous gases to clear.
The condition of the miners was not immediately known. Four co-workers tried to reach them but were stopped by a wall of debris, and the blast knocked out the mine's communication equipment, preventing authorities from contacting the miners.
It was not known how much air they had or how big a space they were in. The miners had air-purifying equipment but no oxygen tanks, a co-worker said.
"You just have to hope that the explosions weren't of the magnitude that was horrific from the beginning," Joe Manchin, governor of the nation's No. 2 coal-producing state, told CNN. He added: "There's always that hope and chance that they were able to go to part of the mine that still had safe air."
Going in
The first of eight search-and-rescue teams entered the Sago Mine more than 11 hours after the blast trapped the miners. Rescue crews were kept out of the mine for most of the day while dangerously high levels of carbon monoxide -- a byproduct of combustion -- were vented through holes drilled into the ground, authorities said.
Company officials believe the trapped miners were about two miles inside the mine, about 260 feet under the ground. The crew entered the mine on foot for fear of sparking another explosion.
The federal Mine Safety and Health Administration sent a rescue robot to the mine, situated about 100 miles northeast of Charleston.
Some 200 co-workers and relatives of those trapped gathered at the Sago Baptist Church, across the road from the mine.
Anna McCoy said her husband, Randall, 27, was among those missing. She said he had worked at the mine for three years "but was looking to get out. It was too dangerous."
Methane builds up
Coal mine explosions are typically caused by buildups of naturally occurring methane gas, and the danger increases in the winter months, when the barometric pressure can release the odorless, colorless and highly flammable gas.
Manchin spokeswoman Lara Ramsburg said the blast may have been sparked by lightning from severe thunderstorms.
But Roger Nicholson, general counsel for the mine's owner, International Coal Group, said that it was not clear what caused the blast and that there was no indication it was methane-related.
The mine has a single entrance, and the shaft winds its way for miles underground. The miners were supposed to be working about 160 feet below the surface, said the wife of one of the trapped men. But it was unclear how far into the shaft they had gone when the blast struck.
Gene Kitts, a senior vice president at ICG, said the company was preparing to drill into the mine to reach the miners.
"If the miners are barricaded, as we hope they are, they would prepare themselves for rescue by rationing," Kitts said. The miners would probably have only their lunches and water on hand.
"These miners are experienced. They are well-trained," Kitts said. "We are just praying they had an opportunity to put their training to use."
The miners had three to 30 years of experience working in the mining industry, Kitts said. The company declined to release their names.
First shift
The blast happened between 6 and 6:30 a.m. as the first shift of miners entered to resume production after the holiday, Ramsburg said.
Thirteen miners were trapped, the coal company said. Four co-workers tried to reach the missing miners but "came to a wall" of debris, said Steve Milligan, deputy director of Upshur County's Office of Emergency Management.
Miners who work in the mine carry individual air purifying systems that would give them up to seven hours of clean air, said Tim McGee, who works at the mine and was among those at the church. They do not carry oxygen tanks, he said.
Federal inspectors cited the mine for 46 alleged violations of federal mine health and safety rules during an 11-week review that ended Dec. 22, according to records.
