Operations Scheduler, Anglo American-Moranbah North Mine
Anglo American has introduced Australia’s first certified, electronic tablet device for use in underground coal mines. The device provides real-time access to CITECT data for Hazard Awareness and system monitoring, as well as Anglo American’s latest Safety and Health Management processes and documentation.
Developed in collaboration with a tablet manufacturer, the device was developed and tested to achieve International Group 1 Certification together with Queensland Government’s SIMTARS safety in mines certification.
The underground tablet can be used as a portable video communication device (via Skype) to instantly access expert technical advice. Not only does this accelerate operational fault-finding, it also allows a live video link to paramedics in the case of an emergency.
The tablet allows real-time environmental monitoring; provides up-to-date equipment resetting requirements; displays risk-categorised Strata Defect locations pictorially on the Mine Plan; and allows short interval control on the actual plan.
The introduction of the tablet is a major step towards the removal of all underground paperwork and the electronic lodgement of statutory and production reports.

- 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.
