Anglo American has been forced to halt operations at its Dawson coal mine following a wall collapse.
The open cut mine saw its high wall crumble on Friday afternoon, according to the Sunshine Coast Daily.
The wall collapsed on to an excavator and a haul truck, however there were no injuries.
Anglo American told Australian Mining in a statement that it "is investigating an incident involving a highwall in one of the pits at Dawson mine on Friday night".
It went on to say that "work is underway to stabilise the mining area and safely return to normal operations".
CFMEU safety representative Greg Dalliston will visit the site to begin investigations tomorrow.
Dalliston said while Anglo American "were definitely luck no one was seriously hurt, [they] should have controls in place to stop that [wall collapse] happening".
He went on to say the mine will remain closed until the investigation has concluded, however he was unable to give a time frame.
The cause of the collapse is unknown.
