Beca provided detailed engineering services for Glencore's Rolleston Open Cut coal mine expansion project. This included a feasibility study to guide works to increase its production capacity in the most cost-effective manner possible.

Glencore's Rolleston site is an open cut thermal coal mine located in Central Queensland's resource-rich Bowen Basin that provides six million tonnes per annum (mtpa) of export-ready coal for overseas markets.

Glencore engaged Beca after deciding to expand the production capacity of their Rolleston Open Cut coal mine from 6mtpa to 20mtpa, extending its lifespan by 20+ years.

Our initial scope of work was to provide detailed engineering design for a flood levee and channel, to capture water run-off from increased mining operations and divert it towards the existing Spring Creek diversion channel.

Following our detailed design work on the Spring Creek diversion channel, Beca were also awarded work on the multi-faceted mine expansion surface infrastructure elements of the project.

The result of our engagement was a series of high-quality engineering documents which formed Glencore’s environmental impact statement and successfully guided the expansion of the Rolleston Open Cut coal mine to its current size. This included site water balance modelling, mine water dams investigation, levee design and groundwater modelling.
