Chilean officials hope to rescue miners 'by weekend'
Above ground there are games to pass the time Engineers drilling to reach 33 trapped miners in Chile say the men might be rescued as early as this weekend.
The head of one of the drilling operations, Pedro Buttazzoni, told the BBC his drill had only 160m (524ft) further to go to reach the men.However, the man overseeing the entire operation has been more cautious about the timetable for their rescue.
The miners have now been trapped underground for two months, longer than any previous group.
Mr Buttazzoni, the head of the Chilean mining company Geotec, said his drill had already cut through 464m (1,500ft) of rock.
He said his team expected to break through to the area where the miners are sheltering in 3-4 days.And he said rescuers were debating whether they would in fact need to line the rescue tunnel with metal casing as planned, a process that would take several days.
If it was decided that the lining was not needed, it was "perfectly possible" that the miners could be brought to the surface by the weekend, he said.
'Dangerous' task The timetable for rescue has shortened dramatically as the three drills racing to reach the miners have made rapid progress.
Last week the government said the rescue attempt would begin in the second half of October, having previously said it would start in early November.
President Sebastian Pinera now says he hopes the miners are rescued before he travels to Europe on 15 October, saying he wants to "share that moment with the miners".
But told of that comment, rescue chief Andre Sougarret said he had no new information to suggest a rescue would be possible before the second half of the month.
President Pinera has taken a close personal interest in the rescue effort But he said it was vital that they continued their fitness training, because pulling them up to the surface would be very stressful.
"That's very dangerous. We want to prevent any type of overheating, because that can produce thermal shock, when your temperature rises above 42C [108F], which decomposes the proteins and you can have a hard time recovering.
"That could be fatal," he said.
Once the rescue shaft is complete, a specially made steel capsule, designed by the Chilean navy, will be lowered.
The plan is for navy commandos to go down to assess the situation and help the miners use the rescue capsule.
It is expected to take an hour to pull each of the trapped men to the surface.
The miners have even begun to send prized possessions and mementos which they don't want to leave behind up to the surface using small capsules, known as "doves," in which they have been receiving supplies through narrow boreholes.
Miners' relatives, who have been camping at the site for the past two months, are preparing a party to celebrate their rescue.
Protest The men were trapped by a rockfall at the mine near Copiapo, about 725km (450 miles) north of the Chilean capital Santiago, on 5 August.
Rescuers had almost given up the search when they located the miners 17 days later.
As the rescue effort continued, other workers employed at the mine staged a protest on the surface, complaining that they had not been paid since the accident.
Chanting "there are more than 33 of us", about 200 workers marched through the town of Copiapo to demand money they say they are owed.
The company which ran the mine has large debts, and is also facing lawsuits from the relatives of the trapped men.
