Anglo American will cut at least 50 jobs when its Moranbah North mine reverts back to a single longwall operation.
It comes on the back of a rash of coal mining job cuts across the Bowen Basin.
BMA recently cut 100 employees from the contractor workforce at its Gregory Crinum coal mine in Queensland.
It has also halted expansion works at its Peak Downs coal mine.
Rio Tinto has cut 70 contractors from its Kestrel-KME operation, as well as slashing positions at its Clermont mine and closing its Blair Athol operation; Xstrata will be cutting contractor numbers on its coal mines but refused to detail how many workers would go or which sites would be impacted.
BHP CEO Marius Kloppers this week said it was part of a "broad industry movement" toward cutting jobs on Queensland coal developments.
Now Anglo American has joined the other major with its announcement it will cut positions, the Daily Mercury reports.
It comes as the mine reduces its operations from two down to a single longwall.
Due to this it will reduce its workforce, and has called on some workers to take voluntary redundancy.
An Anglo spokesperson told the Daily Mercury the decision was made "in light of recent market conditions and declining coal prices".
"This … will reduce workforce and contractor activity across the mine," she said.
"We are currently conducting a review of business requirements for the new operating environment.
"As a result of the operational changes, Moranbah North mine announced a voluntary separation process in which we have invited employees to register a non-binding expression of interest if, based on their personal circumstances, they would like to leave the business," she said.
The CFMEU slammed the shrinking coal operations across the Bowen, stating that companies are cutting jobs because commodity prices have slumped.
[Anglo is] going to reduce operations from two longwalls to one longwall," Smyth explained.
"That's up to 50 jobs as a minimum. It could be more. They are not entirely sure because they are reviewing operations."
There is no word yet as to how this will affect Anglo’s planned development of the Moranbah South and Grosvenor projects.
