COPIAPO, Chile (AP) - Rescuers in Chile are trying to keep 33 trapped miners alive while they figure out a way to rescue them.
The rescuers have been lowering capsules containing rehydration tablets, glucose and oxygen down a long hole leading to the men, who've been able to survive for 2½ weeks on just two spoonfuls of tuna, a sip of milk and a biscuit every 48 hours.
A second hole was punched into the chamber where the miners have
taken refuge. Chile's mining minister says that'll be used for communicating with them, and a third hole will provide ventilation.
Meanwhile, doctors and mental health experts are debating how to keep the miners sane during the estimated four months it could take to dig a tunnel wide enough to get them out of the safety chamber, which is about 2,200 feet underground.
The miners are trying to keep up their spirits. Officials have released a portion of a recording of their dialogue with people on the surface, in which miners are heard singing Chile's national anthem.
