Vale’s Carborough Downs underground mine is located in Central Queensland’s Bowen Basin, 180 kilometres southwest of Mackay. Walz Group was engaged to perform the structural, mechanical, piping, and electrical installation of the 5km overland conveyor and upgrade of the coal handling and preparation plant (CHPP). This  formed part of a broader brownfields expansion. In total, we constructed almost 6km of conveyor systems (drift, stockpile, reclaim, reflect, overland and surge bin conveyors) and associated componentry.

Our works included:

• Structural steel installation — trestles, conveyor gantries, transfer stations
• Mechanical installation — belt weighers, scrapers, drive motors, pullies, external gravity take-up
• Installation of victaulic and screwed pipework
• All electrical installation
