Drilling to start to free trapped miners
Wednesday May 3 07:00 AEST
Rescue teams say a boring machine is today expected to begin drilling a one metre-wide tunnel to trapped miners Todd Russell and Brant Webb through the last 12 metres of rock — a task expected to take 48 hours.
That could see the men emerge from Tasmania's Beaconsfield Gold Mine some time on Friday — 10 days after rock falls on April 25 trapped them underground and killed their mate Larry Knight.
A cement platform to anchor the specialised equipment called a raiseborer was being finished, but the workers underground had to ensure everything was right, Australian Workers Union national secretary Bill Shorten said.
"In order to not to have to start all again, they've to get the direction of the machine right," Mr Shorten told Today.
"It's got to be aligned just so to where the blokes are so they can get out easily.
"But they've got to set this big machine on a pad of concrete. The last concrete trucks came up at 5.30 this morning."
He said the concrete now needed to set.
"What they're doing is they're putting some accelerants in the concrete to help it set more quickly but they've got to make sure that's done right, that will take a period of some hours, then they'll see if the drilling can start", he said.
"I think in the course of the day, drilling will start, but it won't be happening...in the next couple of hours, but in the course of the day."
Mr Webb and Mr Russell, who have been pinned underground since Anzac Day, are in remarkable health and good spirits despite frustrating delays in digging them a tunnel to freedom.
They had a supply of food, water, dry clothes and blankets on Tuesday night, and even magazines as they faced their eighth night buried in a steel cage one kilometre below ground.
The "cheeky" miners have told rescuers they desperately want to be out on time for the weekend footy - and they may just get their wish.
While their families face an agonising wait, the two miners are able to joke about their ordeal.
Mine manager Matthew Gill said the men had asked for meat pies and eggs and bacon, but "that's just not possible".
"One wanted Saturday's paper because he had resigned. I think that was Todd. And the reason he wanted Saturday's paper was because he was going to look for another job," he said.
The miners' extraordinary ability to cope with their confinement - born from years of experience underground - has bought rescuers valuable time to find the safest way to get them out.
Mr Russell, 34, and Mr Webb, 37, were on Tuesday helping guide rescuers setting up the $6 million raise borer machine that will chew its way through rock towards them.
"These miners are helping rescue themselves," Mr Shorten said.
With tungsten steel blades that turn rock into dust, the borer is considered safer than drilling and blasting, but the final stages of the operation promise to be very tricky.
Rescuers are also looking at other standby strategies.
Mine manager Matthew Gill said the crews would going as fast as they could, but safety was paramount.
"They are hydrated, well fed and receiving medical advice and are in good spirits. We will not rush to jeopardise this.
"These guys are actually giving us a lot of information to allow us to work out an appropriate plan."
Mr Gill said 16 people were working underground, including miners, drill operators, fitters, electricians and mine emergency personnel, a clinical psychologist and a paramedic.
Apart from minor injuries suffered trying to dig their way out after the rock fall, the two were reported to be warm and comfortable.
They may want meat pies, but medical teams, cautious about the diets, are instead feeding them vanilla-flavoured nutritional drinks and vitamins pushed to them through a 90 millimetre PVC pipe.
Bedding and a tarpaulin have also been delivered to them through the pipe and there are no problems with air quality.
They are able to crawl outside the 1.2 metre by 1.2 metre cherry-picker cage into a small gap between the cage and rock wall, but have largely stayed put on rescuers' advice.
"So there is a little bit of room to move, but they are not out there doing callisthenics," Mr Shorten said.
Messages had been exchanged between the men and their families via their rescuers, but officials won't reveal their contents.
Psychologists are monitoring communications with the men.
Asked whether the miners were frustrated by the delay, Mr Shorten said: "I can't imagine anyone is happy being there.
"I think they understand that what's being done is in their interests."
Medical authorities are optimistic that Mr Russell and Mr Webb will emerge without any major or long-term medical problems, and may only need to spend 48 hours in hospital after their ordeal is over.
"They are in remarkable condition, physically and psychologically, at this time," said Tasmanian Medical Retrieval Services director Andrew Hughes.
The gates of the mine have already become a site for prayers and tributes, adorned with three bunches of flowers and where a local woman, who declined to give her name, spent an hour crouched and praying.
