During normal operation at the Water Treatment Plant the inlet screen in the Bio Reactor blocks with debris, sludge and fecal matter. The cleaning of the inlet screen was a laborious task that exposed maintainers to raw sewage and repeated manual handling risks. The crew came up with an engineering control that completely prevented the inlet screen from blocking, eliminating the need to remove and clean the screen. With this new system functioning the crew have removed a great deal of frustration and reduced the handling of this inlet screen to planned maintenance intervals and significantly reducing the crew’s exposure to the biological risk.

- Post explosion atmosphere monitoring:– An industry study into available, low powered, sensors were conducted. The study was to identify commercially available equipment to sample the mine atmosphere post an underground incident.
- Ultra-resilient communication system:– An investigation was undertaken into the feasibility of components for a robust and resilient mine communication network. The network must survive an underground incident and be able to transmit information in and out of an underground mine environment.
- Blast protection (or blast resilience):– The blast protection was evaluated through subjecting different shapes of enclosures to actual blasts, in an explosion propagation tube.
- Navigational aids:– A series of test were undertaken to determine the suitability of using visible light, infra-red as well as radar to aid in self rescue. All test were undertaken in a “dusty”, or low-visibility, environment.
