AGL Energy has awarded a contract to BMT Group’s subsidiary BMT WBM to design a new conveyor system for the company’s Loy Yang mine located in Victoria, Australia.
The open-cut mine supplies coal for the power stations Loy Yang A, owned by AGL Energy, and Loy Yang B, which is 70% owned by GDF SUEZ Australian Energy and 30% by Mitsui.
The new conveyor can transport up to 8,500t/h of material on 2m-wide belts running at 5.3m/s. It will be used to transport overburden from Loy Yang mine to a new internal dump in the mine’s worked out section.
AGL Energy spokesperson said: "AGL Energy is pleased that BMT is supporting the delivery of environmental improvements to its Loy Yang Mine.
"BMT’s innovative design will ensure that overburden will be moved efficiently and effectively to the new internal dump, backfilling and rehabilitating the mine as part of its day to day activities."
With this new project, AGL Energy will be able to comply with its environmental goals by the way of mine rehabilitation and energy saving measures.
As part of the contract, BMT will look after the overall design, provide the detailed design for civil, structural and mechanical elements, and is also responsible for liaising with AGL Energy’s in-house team delivering the electrical design.
The 1.34km long downhill system will use three 1,000kW variable-frequency drives to generate power and introduce it back into the grid.
BMT has designed the conveyer as a modular system to allow for unstable ground conditions and will deliver a power saving of around five megawatts (MW) over the existing system.
BMT WBM machinery group state business unit manager Peter Essig said: "BMT has a long, successful history working with AGL Energy, including being involved with this project since 2006 when we produced the initial conceptual design."
