BELLEVUE GOLD CASE STUDY 1
VENT SHAFT DEWATERING
This historic mine was closed for over 20 years. The deepest part of the Bellevue mine reaches about 430 metres below the surface and stretch for 28 kilometres underground. The target water level UON has achieved to date is over 300 metres below ground level.

UON were tasked with delivering a dewatering solution for an old mine being reactivated, via an existing ventilation shaft. This required a custom shaft cap to be designed and fabricated to facilitate two 147 kW submersible pumps, installed to a depth of 300 m. Additional telemetry was provided to monitor multiple level sensing probes and to enable full remote access control.
UON deployed electric pumps powered by our GMC generators to deliver over 30% fuel savings compared to competitors.
- 2 bore pump assemblies and associated downhole equipment
- 2 dewatering bore head works and (Patent-Pending) UON GMC© Generators
- Telemetry system and integration into SCADA system
- Designed and built in 14 days
- Installed in 6 days
Supply and Installation of Power Station for Underground Mining
The FMG magnetite iron-ore mine was a new trial mine.
The key success of the rapid-deployment 6 MW / 11 kV power station was the modularization and flexibility of all equipment provided as part of UON’s complete solution
UON was contracted to design, manufacture and install a pontoon system to dewater over 7 Billion litres from an old open pit mine.
The key success of the Rapid-Deployment 30MW Power Station was UON’s time management and orchestrated scheduling of people and plant.
UON were tasked to Supply, Manufacture and Install Major Dewatering Works and Transfer System.
