Drill Nears Trapped Miners

Families of the Chilean miners wept and cheered Saturday after a drill carved a hole wide enough for the 33 trapped miners to be pulled out one by one – raising hopes that they will be rescued within days.

Relatives waved the Chilean flags and shouted with joy after they heard the siren confirming the escape – but authorities cautioned that the most difficult task is still to come. Engineers must first check the shaft and decide whether to reinforce it before pulling the miners to the surface.

"We feel an enormous happiness, now that I'm going to have my brother," said Darwin Contreras, whose brother Pedro, a 26-year-old heavy machine operator, is stuck down below.

"When the siren rang out, it was overwhelming. Now we just have to wait for them to get out, just a little bit longer now."

The "Plan B" drill reached the miners at a point 2,041 feet (622 meters) below the surface at 8:05 a.m., after 33 days of drilling.

Jeff Hart of Denver, Colorado, operated the drill, and said the entire rescue crew erupted with cheers when the T130 broke through.

"There is nothing more important than saving, possibly saving 33 lives. There's no more important job than that," Hart said. "We've done our part, now it's up to them to get the rest of the way out."

The milestone thrilled Chileans, who have come to see the rescue drama as a test of the nation's character and pride, and eased some anxiety among the miners' families.

But now comes a difficult judgment call: The rescue team must decide whether it's more risky to pull the miners through unreinforced rock, or to insert tons of heavy steel pipe into the curved shaft to protect the miners on their way up.

"This is an important achievement," Mining Minister Laurence Golborne said, "but we still haven't rescued anybody. This rescue won't be over until the last person below leaves this mine."

President Sebastian Pinera promised "to do everything humanly possible" to keep the miners safe, and as the drill was nearing the breakthrough, he said he had kept his promise.

Those in charge of the rescue say the decision on how to proceed next will be a purely technical one. But everyone involved knows how terrible it would be — politically as well as for the families — if a miner gets stuck partway up for reasons that might have been avoided. While engineers have said the chance of something going wrong in the unreinforced shaft are remote, the risks must be weighed.

Steel pipe would prevent stones from falling and potentially jamming the capsule, but it wouldn't save a miner if the unstable mine suffers another major collapse, and might itself provoke a disastrous setback, Golborne said.

"You would have to put though a 600-meter hole a lot of pipes that weigh more than 150 tons," he warned. "And this structure can be set in a position that also could block the movement of the Phoenix (escape capsule). It's not an decision easy to make."

If Saturday's close video examination persuades engineers that the shaft is smooth, strong and uniform enough to let the capsule pass without significant obstacles, then rescuers plan to start pulling the men out one by one as early as Tuesday, in a made-for-TV spectacle that has captivated the world.

The miners will be initially examined at a field hospital where they can briefly reunited with up to three close relatives. Then, they'll be flown by helicopter in small groups to the regional hospital in Copiapo, were a wing of 33 fresh beds await to care for them for no fewer than 48 hours. Only after their physical and mental health is thoroughly examined will they be allowed to go home.

"I'm very excited, very happy," said Guadalupe Alfaro, waving a flag outside her tent. Her son Carlos Bugueno, 26, is stuck down below. "I'm very excited, very content. I've wanted so long for this moment, I woke up to live this moment. My son will return soon."

"Our nervousness is gone now," said Juan Sanchez, whose son Jimmy is stuck in the mine. "Only now can we begin to smile."
