Families Of Trapped Miners 'Desperate'

Relatives of 65 coal miners trapped underground by a gas explosion grew increasingly desperate and frustrated as rescue workers emerged from the pit with no news of their loved ones.

It was unlikely the miners were still alive, officials said Monday. But they maintained there was still a chance of finding survivors trapped by Sunday morning's explosion at the Pasta de Conchos mine near the town of San Juan de Sabinas, 85 miles southwest of Eagle Pass, Texas.

Some of the miners' family members, who had been camped outside the mine for more than 36 hours, called for rescue workers to give them more information.

"Tell us the truth!" a man shouted through a megaphone.

Jesus de Leon, 50, whose 35-year old son is trapped underground, said the wait was a torment for his son's mother and sister.

"If the rescue workers have advanced just one more meter we need to know about it," De Leon said. "They don't tell us anything."

Some relatives prayed with priests and pastors who joined them at the pit's entrance.

Women wept openly and swayed with their arms in the air and men wiped tears from their eyes.

"We are waiting for a miracle from God," said Norma Vitela, whose trapped husband, Jose Angel Guzman, had previously told her of problems with gas in the mine. She said the father of four, who earns 800 pesos — about $76 — a week, could not afford to quit.

CBS News correspondent Lee Cowan reports mining accidents are not uncommon here. The worst in recent memory killed 34 miners in 1988.

The trapped men had carried only six hours of oxygen, but officials said they believed a ventilation system that uses huge fans to pump in fresh air and suck out dangerous gases was still working. Even so, they could not be certain the precious oxygen was arriving to where the miners were trapped.

Juan Rebolledo, vice president of international affairs for mine owner Grupo Mexico, said oxygen tanks were scattered throughout the mine, but it was impossible to know if the trapped miners had access to any of them.

More than 36 hours of digging had pushed rescue teams 400 yards into the mine, about 110 yards from where two conveyor-belt operators were believed to be trapped, said Sergio Robles, director of emergency services for Coahuila state.

But others were thought to be trapped as far as one to three miles from the mine's entrance.

Robles said rescuers avoided using electric or gas-powered machinery because of the presence of explosive gases. Medical doctors were on the site to examine rescue workers as they emerged from their eight-hour shifts in the tunnels.

At least a dozen workers who were near the entrance at the time of the explosion were able to escape. They were treated for broken bones and burns.

Asked whether he believed there were more survivors, Robles said: "It would be difficult because of the presence of gas. But we are holding out hope of finding someone alive."

Robles said the roof of the mine was better reinforced after 400 meters, giving rescuers hope that they might be able to advance more quickly. He said if there were survivors, they could very well be trying to dig their way out.

Family members prepared for a second night outside the pit, huddling near bonfires and wrapped in blankets to protect against the bitter cold. Some pitched tents, while others slept on small cots or upright in plastic chairs.

"The only thing we want is information and all they tell us is that they don't know," said a sobbing Yadira Gallegos, whose 28-year-old brother-in-law, Jesus Martinez, was just finishing his first week at the mine.

The explosion occurred around 2:30 a.m. local time Sunday as the miners were in the middle of their overnight shift.

Consuelo Aguilar, a spokeswoman for the National Miners' Union, said there had been concern over safety conditions in Grupo Mexico mines. She called for an investigation into the cause of the accident and the responsibility of company officials.

Rebolledo said safety conditions met Mexican government requirements as well as international standards, "but accidents can always happen."

He said the union had raised no major disagreements over safety in annual meetings with the company and mine administrator Ruben Escudero denied any company negligence, saying, "These mines can't operate if they don't meet the established minimum requirements."

Pedro Camarillo, a federal labor official unrelated to Olivia Camarillo, told reporters during a news conference that officials found nothing unusual during a routine evaluation on Feb. 7.

As well as mining coal, Grupo Mexico is the world's third-largest copper producer, with operations in Mexico, Peru, and the United States.

Coahuila's worst modern mining disaster occurred in 1969, when more than 153 miners were killed in a pit at the village of Barroteran. In 2001, another 12 people died in an accident at a mine near Barroteran.
