Dr Lynham vowed to leave "no stone unturned" as safety was re-evaluated.

"Two expert independent reviews are now under way to identify changes needed to improve health and safety in the state’s mines and quarries," he said.

"Forensic structural engineer Dr Sean Brady is examining all fatal incidents in Queensland mines and quarries since 2000.

"I have broadened this review. It was originally coal mine incidents only to the end of 2018, but will now include mineral mine and quarry incidents, and all fatal incidents this year."

In addition, Dr Lynham said the University of Queensland was reviewing the state's mining health and safety legislation.
