Broadmeadows running on fresh air

Supplier News

MACKAY Air Fluids and Kaeser Compressors have installed three ESD441 air compressors equipped with two TH451 Dryers and a Sigma Air Manager at BMA Broadmeadows underground coal mine.

The compressed air drives pneumatic equipment underground.

Originally an open pit operation, access to the Broadmeadows underground mine in Queensland’s Bowen Basin was gained through the above ground pit.

Underground construction involved drilling and blasting the highwall; removal of Goonyella middle seam coal, removal of mud and silt by truck and dredge, compaction of overburden material, in-pit roads, and open lined and unlined drains.

Golding Contractors installed in-pit conveyor ramps and built a tailgate pad, three main gate pads and steel Hel-cor culverts.

Kaeser Compressors’ Kent Clark says the three large ESD Kaeser compressors and two dryers now supply the underground mine with all its dry air needs.

“Air system reliability and efficiency are essential to achieve the high quality standards that mine sites such as the Broadmeadows coal mine demand,” Clark says.

“The ESD rotary screw compressors from Kaeser Compressors are specifically designed to meet these requirements and provide highly efficient, modular compressed air solutions that have been individually tailored to this coal mine,” he says.

The internal PC-based Sigma Control compressor controller is fitted as standard on the compressor model.

“The user-friendly controller offers greater energy saving potential, reduces maintenance and increases compressor system reliability and availability,” Clark says. “The Sigma Control also enables direct communication with the Sigma Air Manager compressor management system, which provides seamless interaction between all components in the compressor system and offers complete air cost transparency.

“This ensures that air costs are monitored and controlled to ensure the mine site is operating at its most efficient,” Clark tells Australian Mining.
