On Sunday, Mining Minister Laurence Golborne reiterated the government's estimate of three to four months to rescue the men, rejecting local reports citing engineers who said it could be done in much less time. Golborne said that experts had analyzed 10 different methods to get the men out, will continue to study other options, but that "nothing has yet been found that will be quicker." Normally, after completing a pilot hole, the opening is enlarged by drilling from the bottom up. The drill, hanging at the bottom of the pilot hole, is reached through existing shafts in a mine and then fitted with the machine cutters, which then blast through rock as they are raised. In this case, however, there is no way to get those large cutters to the bottom of the mine; if there was a hole large enough to reach it, the men would already have been rescued. Araya said that knowledge gained drilling the initial holes, which are between 20 and 100 yards (meters) from the shelter, would give the team digging the rescue hole a head start. For example, while penetrating rock, the circular motion of the bits causes the drill to veer right. In this case, the especially hard rock exaggerates that, making constant correction necessary, he said. From the moment the mine collapsed, the trapped men have had a central role in keeping themselves alive
-- getting to the safety chamber, rationing food and keeping order with extraordinary discipline. Still, many questions remain. What physical and mental condition will the men be in when they are called on to help save themselves? "We will keep them alive, in good shape and health," said Golborne. "That is something that is happening in parallel while we are digging the larger hole." Other steps are being taken to keep the men as strong as possible -- physically and mentally. Telephone wire was being snaked down one of the bore holes on Sunday, and Golborne said that within a few hours one representative from each family would be allowed to talk to one of the miners
-- the first verbal communication they would have. Until now, handwritten notes have been passed through tubes sent up and down the bore holes. Physically, many of the men have severe skin irritations from the hot, wet conditions underground and were sent special clothing that dries quicker and also small mats to sleep on so they don't have to rest directly on the damp ground. For now, the men have some time to prepare before they start the arduous task of hauling away the rock that stands between them and freedom, but questions remain. Sougarret, the operation leader, said it will be one to two months before large quantities of rocks start falling. Can the men do such hard labor for a couple months just on food that will fit down the narrow tubes? And then there is what will be a harrowing rescue:
Each man will be pulled up through the 26-inch (66-centimeter) hole in a tube, a ride that will take about an hour each.
