Chile seeks to speed rescue of trapped miners

A second escape shaft could cut in half the time needed to reach 33 men trapped underground, Chilean rescuers said.

Chile is looking at ways to speed the rescue of 33 miners trapped deep underground, hoping to cut in half the time to bring them to the surface.

Mining Minister Laurence Golborne said rescuers were considering other options, including digging a second escape shaft to rescue the miners, who survived more than two weeks on mouthfuls of tinned tuna, cookies and milk before a slender shaft reached them.

"Obviously we are looking into other options and we will welcome any option that speeds up the rescue," Golborne said at the mine in the rugged mountains of the Atacama desert near the city of Copiapo.

Officials plan Sunday to start digging a shaft about 2 feet in diameter that would take three months to reach the trapped miners. They would be lifted up one by one with a pulley.

Rescuers said Saturday they were considering drilling a second shaft closer to the tunnel where the miners are located that would take about 60 days to reach them.

"We are very happy. Any possibility of bringing them out sooner is great news," said Cristina Nunez, 26, whose husband, Claudio, is trapped underground.

The miners were found alive last Sunday after they tied a note to a drill looking for them 2,300 feet underground, triggering celebrations across Chile and focusing world attention on what would be the toughest mining rescue ever attempted.

In a video released this week, bearded miners, some of them noticeably thin, explained how they organized themselves to survive in a tiny refuge in the bowels of the mountain.

They said they had areas designated to sleep and play dominoes as well as a space for water and items like toothpaste and deodorant.

Government officials are worried five of the men have started to show signs of depression after they did not appear in a video filmed by the miners.

The government is bringing in NASA experts for tips on how to help the miners cope with lengthy confinement.

Rescuers have started to lower card games, miniature video projectors and MP3 players to battle boredom inside the hot and humid tunnel.

The San Jose mine accident has put the spotlight on safety conditions in the world's top copper producer where authorities have closed at least 30 small mines since the Aug. 5 cave-in.

The government has also promised changes to safety regulation, although stricter controls and closures of small mines are unlikely to dent copper output significantly. (Writing by Alonso Soto; Editing by Peter Cooney)
