An investigation is under way after unexplained ground movement was recorded at Mount Isa Mines.
A spokeswoman for the copper mine said at around 9:30pm last Friday night, the underground mine recorded movement which is thought to have come from an abandoned part of the mine.
Residents in the area also reported feeling the ground shake and hearing loud banging noises, ABC reported.
The spokeswoman said emergency procedures were activated, with workers moved to safety.
No one was injured as a result of the incident.
Ground movements underground can be extremely dangerous.
On ANZAC day in 2006 a small earthquake triggered a rockfall at the 100 year old Beaconsfield gold mine in Tasmania.
The mine collapse killed miner Larry Knight and trapped Brant Webb and Todd Russell for two weeks.
