WHS Management for Underground Mining

Manage ventilation, ground support, diesel particulate exposure, and emergency response in underground mining environments.

Underground mining concentrates the full spectrum of mining hazards into enclosed environments where ventilation is the primary control for atmospheric contaminants, ground support systems are the only barrier against rockfall and collapse, and emergency egress options are severely limited. The introduction of Australia's first DPM workplace exposure limit at 0.1 mg/m3 will have its greatest impact on underground operations where diesel-powered loaders, trucks, and utility vehicles operate in enclosed headings with finite ventilation capacity. The nitrogen dioxide WEL reduction from 3 to 0.5 ppm — an 83 per cent drop — will challenge blast re-entry procedures and ventilation clearance times. A dedicated WHS management plan ensures your underground operation addresses atmospheric, geotechnical, and emergency response hazards under current and incoming requirements.
