A search is about to begin for a man believed missing in a West Coast mine.
A Tasmania Police spokesperson said police and emergency services were on the scene at the Henty Gold Mine where a worker was believed missing underground.
The spokesman said the worker was reported missing about 4am after his colleagues could not make communications contact with him and entered the area he was working in, about 20 minutes descent underground.
"The three men found a section of earth collapsed and were unable to locate their colleague. They went back to the surface and raised the alarm," the police spokespersons said.
"When they deem it safe the mine's rescue team will commence searching."
Work Safe Tasmania and the Mines Inspector have been notified.
