Underground and Surface Mining Infrastructure
Engineering, fabrication, construction and electrical, control and instrumentation delivered by one accountable team.
TDS Projects Group is a multidisciplinary engineering, construction and fabrication provider to the mining sector, specialising in underground mining infrastructure, bulk material handling and electrical, control and instrumentation projects. We design and execute infrastructure that supports safe, efficient and sustainable mining operations throughout their lifecycle.
Our integrated team takes projects from concept development and detailed design through precision fabrication, site erection, commissioning and operational support, under a single point of accountability. We understand the demands of the underground environment and develop practical solutions that maximise productivity while maintaining the highest standards of quality and safety.
Underground Mining Expertise
Our teams design and build the infrastructure that keeps underground operations moving, from ore handling and dewatering to shaft equipping and power.
Underground Ground Handling Systems
Design and erection of high-capacity underground tipping arrangements, hydraulic bulkheads, ore passes, knife-gate retaining walls, apron feeders, jaw crushers, vibrating grizzlies, and overland and underground conveyor belts.
Mine Dewatering and Pumping Stations
High-head, high-volume underground dewatering infrastructure, including dirty water cascade pumping systems, high-rate settlers, filter presses, mud presses, degritter systems and multi-stage pump stations with positive displacement pumps operating up to a 700 m vertical head.
