A thermal imaging drone will be used to search through rubble for a worker after a mine collapsed in Tasmania in the early hours of this morning.
Thermal imaging has failed to detect any signs of life in the search for a worker missing after an earth collapse at Tasmania's Henty Gold Mine.
Colleagues of the worker raised the alarm about 4am today when they couldn't contact or find him.
The man was working in the lower levels of the mine in a loader, filling a truck, while on night shift, PYBAR Mining Services chief executive Brendan Rouse told reporters.
"It was the truck driver who identified he didn't come back with the next load," Mr Rouse said.
"We're all obviously distressed."
Three co-workers discovered a section of collapsed earth in the area he had been working, about 20 minutes descent underground.
Emergency crews sent down a thermal imaging drone and robotic camera shortly after midday and had hoped to locate him within the hour.
However, by 3pm they confirmed they had not found the worker, who has been employed at the mine for about two years.
"Search crews have now returned to the surface after using a thermal imaging drone and a robotic camera to investigate the collapsed area," the Emergency Management Department said in a statement.
"They are currently reviewing the footage from the scene and have not yet located the man or identified signs of life."
Australian Workers' Union national secretary Daniel Walton said the union was also on-site supporting workers and emergency services in the rescue effort.
"We have reached out to our members and spoken to a number of workers who are understandably shaken," he said in a statement.
"In circumstances such as these, rescue efforts are extremely delicate and sensitive and our full support is with the specialists."
