COPIAPO, Chile Their self-imposed rations were meager: Two spoonfuls of tuna, a sip of milk, a bite of cracker and a morsel of peach every other day.
That iron discipline kept 33 miners trapped a half-mile underground alive for 17 days on just two days worth of emergency rations. And the same strength may be needed while they wait for rescuers to dig a tunnel wide enough to get them out � an operation that Chilean officials say may take until Christmas.
The way that they have rationed the food, just as theyve performed throughout this crisis, is an example for all of us, Mining Minister Laurence Golborne said Tuesday after talking with the miners at length the night before through an intercom system lowered into their underground refuge.
Chilean President Sebastian Pinera vowed not to abandon the trapped miners in a telephone conversation Tuesday afternoon with Luis Urzua, the 54-year-old shift foreman who has been the miners leader.
You will not be left alone, you have not been alone. The government is with you all, the entire country is with you all, Pinera said.
The miners were plunged into darkness by the Aug. 5 collapse of the main shaft of a gold and copper mine that runs like a corkscrew for more than 4 miles 7 kilometers under a barren mountain in northern Chiles Atacama Desert. They gained contact with the outside world Sunday when rescuers drilled a narrow bore-hole down to their living-room-sized shelter after seven failed attempts.
Its been like a heart thats breaking, but were thankful theyre all alive, bore-hole driller Rodrigo Carreno told The Associated Press as he prepared to leave Tuesday. We did everything we could to save them, and in the end we succeeded.
The miners said they conserved the use of their helmet lamps, their only source of light other than a handful of vehicles whose engines contaminate the air supply. They fired up a bulldozer to carve into a natural water deposit, but otherwise minimized using the vehicles.
The miners can still reach many chambers and access ramps in the lower reaches of the mine, and have used a separate area some distance from their reinforced emergency refuge as their bathroom. But they have mostly stayed in the refuge, where they knew rescuers would try to reach them.
The room has become stiflingly hot and stuffy. Leaving it allows them to breathe better air, but wandering too far is risky in the unstable mine, which has suffered several rock collapses since the initial accident. Its also spooky, since headlamps can illuminate only small areas of the vast space.
Rescue efforts advanced considerably Tuesday as a third bore-hole prepared to break through to the miners, and a huge machine arrived from central Chile for carving a tunnel just wide enough for the miners to be pulled out one-by-one. That machine wont begin drilling for several days.
Andres Sougarret, the rescue efforts leader, estimated it would take three to four months to get the men out. But Davitt McAteer, a former assistant secretary of the U.S. Mine Safety and Health Administration, called that perhaps the most conservative model.
Twenty-five hundred feet is not a terribly, terribly big hole to drill, McAteer said. We ought to be able to get them out in a period of weeks, not months.
Meanwhile, three 6-inch-wide 15-centimeter shafts will serve as the miners umbilical cords � one for supplies, another for communications and a third to guarantee their air supply.
A steady flow of emergency supplies was sent down Tuesday in a rocket-shaped metal tube called a paloma, Spanish for dove. The paloma is 5 1/4 feet 1.6 meters long and takes a full hour to descend through the bore-hole.
The supplies included 33 small low-intensity and low-energy LED lights, so each miner can have a light source that wont bother his eyes in the murky depths. Also sent down was more nutritive food in the form of a vitamin-enriched gel, along with eye patches, aspirin and medicine for one miner who has diabetes and another who suffers from the respiratory disease silicosis, Health Minister Jaime Manalich said.
Family members who have maintained an anxious vigil outside the mine were encouraged to send down notes. First was Lila Ramirez, answering the Dear Lila letter from her husband, Mario Gomez, that thrilled the nation when the president read it aloud Sunday, providing the first details of the miners survival.
I wrote him just now and told him to be very patient, that were all camped out here, following his every heart beat. That he shouldnt become desperate, and that he try to be extremely tranquil, Ramirez told the AP.
With each passing day, the families have been praying for their trapped husbands, fathers, brothers and boyfriends in tents surrounding the mine entrance, where cold nights end in a chilly fog. Theres a bonfire to keep warm, and barbecue and other food donated by the local government in a common tent.
Were not going to abandon this camp until we go out with the last miner left, said Maria Segovia. There are 33 of them, and one is my brother.
In one more week, the men will have been trapped underground longer than any other miners in history. Last year, three miners survived 25 days trapped in a flooded mine in southern China. Few other rescues have taken more than two weeks.

This version CORRECTS in the 6th paragraph that the mine contains gold and copper, instead of gold and silver.
