A miner has died at Anglo American's Grasstree coal mine.
According to Anglo American the worker was found collapsed while working underground.
Emergency personnel responded immediately and attempted to revive the worker, before bringing them to the surface.
However they were unsuccessful in their attempt to revive the miner.
"Anglo American is working with the Mines Inspectorate and Queensland Police to conduct a thorough investigation into the fatality," Anglo American said in a company statement.
According the the QLD Department of Natural Resources and Mines the worker, an electrician, is believed to have asphyxiated when they entered a closed off area of the mine, according to the Daily Mercury.
"Mine management reported that an electrician working underground was discovered unconcious at approximately 3pm yesterday," a DERM spokesperson said.
"Preliminary indications suggest the electrician entered a closed area of the underground mine workings and may have been asphyxiated by a noxious atmosphere."
All underground workers have been withdrawn as a precaution.
The miner has officially been named as 34 year old Paul McGuire.
