The mining union has called for a 24-hour shutdown to allow the industry to "reset" following two deaths in two weeks at Queensland mines.
Glencore, who operate the Collinsville Mine, said they are organising support for the family and work colleagues of the minors who were killed at work.
Glencore CEO Geoff Caton said the company is working closely with police and the state's Mines Inspectorate to conduct a full investigation of the accident.
