Glencore has announced it will cut 100 positions from the Clermont open cut coal mine.
Workers were yesterday told that around 100 positions would be removed from the site by October this year.
The site will continue to employ a workforce of approximately 600 after October.
According to the internal announcement Glencore explained that "we are facing increasingly difficult times due to a combination of continued low coal prices and a resilient Australian dollar...unfortunately we are not immune to these conditions".
Glencore took over management of the coal mine in June this year, after buying Rio Tinto's 50 per cent stake for more than $1 billion.
It first highlighted the potential for worker reductions at the site following its initial acquisition of the operation.
"When we acquired our stake in Clermont in June and took over operations we sad that we would be reviewing operations as part of the integration process," the company stated.
"Over the past three months we have focused on reducing costs and on achieving gains in productivity and efficiency - today's announcement is one outcome of this review."
Speaking to Glencore it said it has looked to redeployment into its other Australian coal operations where vacancies exist.
It went on to state that "despite the current challenges the mine remains an important part of our coal portfolio and we do not expect that these changes will impact on Clermont's annual coal production, which is expected to be around 13 million tonnes by the end of 2014".
