Unique challenge For Chilean Miners. Stay Slim For Rescue.

One challenge is that in order for the miners must fit through a rescue hole they must be no more than 45 inches around the waist. Exercise programs are in place for this. Also, NASA astronaut Jose Hernandez said that the space agency, with its long research on aiding astronauts isolated in space, could help the Chileans understand how to provide "psychological support for those trapped

Chile faces unique challenge in maintaining miners  
Thursday, Aug. 26, 2010

: "COPIAPO, Chile -- In less than a week the 33 miners trapped under Chile's Atacama Desert will have been stuck underground longer than any others in memory - taxing authorities Thursday with unique challenges on coaxing them and their families through the ordeal.
A team of submarine commanders was called in for advice on close-quarters living. NASA is advising on 'life sciences' and giving the men a sense they control their own destinies. Exercise programs are in place so the miners are skinny enough to fit through a rescue hole.

Even a masseuse roams a makeshift camp for the miners' families, relieving tensions with a touch.

All in an effort to confront the unique challenges being faced by all involved to bring the miners out alive.

Extreme patience is seen with each new day that breaks over Camp Hope - where the families of the miners have erected tents, awaiting their loved ones - but there are high expectations for results.

Drilling Begins in Chile Mine Rescue
Published: August 31, 2010  By THE ASSOCIATED PRESS

"SAN JOSE MINE, Chile (AP) -- The effort to save 33 Chilean men trapped deep in a mine is an unprecedented challenge, mining safety experts said Tuesday. It means months of drilling, then a harrowing three-hour trip in a cage up a narrow hole carved through solid rock.

If all of that is successful, the freed men will emerge from the earth and ''feel born again,'' said an American miner who was part of a group dramatically rescued in 2002 with similar techniques. But that rescue pulled men from a spot only one-tenth as deep."

''They're facing the most unusual rescue that has ever been dealt with,'' said Dave Feickert, director of KiaOra, a mine safety consulting firm in New Zealand that has worked to improve China's dangerous mines. ''Every one of these rescues presents challenging issues. But this one is unique.''

First, engineers must use a 31-ton drill to create a ''pilot'' hole from the floor of the Atacama Desert down 2,200 feet (700 meters) to the area in the San Jose mine where the men wait.

Then, the drill must be fitted with a larger bit to carve out a rescue chimney that will be about 26 inches (66 centimeters) wide -- a task that means guiding the drill through solid rock while keeping the drill rod from snapping or getting bogged down as it nears its target.

Finally, the men must be brought up one at a time inside a specially built cage -- a trip that will take three hours each. Just hauling the men up will itself -- if there are no problems -- take more than four days.

''Nothing of this magnitude has happened before; it's absolutely unheard of,'' said Alex Gryska, a mine rescue manager with the Canadian government.
