Conveyor Design, Loy Yang Coal and Overburden Conveyors

Concept design, detailed mechanical and structural design, preparation of plant specifications, technical support during manufacture and erection


Project Involvement


Loy Yang Mine uses four bucket wheel excavators, each with a dedicated face conveyor and downstream conveyor systems, taking coal to power stations and waste to overburden dumps. Loy Yang plays a critical role in supplying two coal-fired power stations (totaling 3000MW). Recently the mine had grown to a size where it was practical to re-arrange the conveyors at the bottom of the mine and start dumping overburden at the bottom.

We undertook the conceptual and detail design of the new trunk conveyor L400, and new overburden conveyors L702 and L705, plus modifications to other conveyors. The design permitted major parts of the new structures to be built before the changeover outage and minimized the outage work.


The new conveyor structures were designed and detailed so that they could be made in either Australia or elsewhere. AGL chose to procure the steelwork in China, and we provided technical support throughout the manufacturing. The new conveyors were completed and commissioned in in March 2017.
