Ventilation and Environment

Underground environments present unique challenges for geological work. Ventilation Primary - Main fan systems - Return airways - Minimum velocity standards Secondary - Auxiliary fans - Flexible ducting - Required for development headings Environmental Hazards Gases - CO carbon monoxide from blasting, equipment - Radon in uranium/thorium deposits - Methane in some coal or organic-rich rocks Dust - Silica from quartz-rich rocks - Wet drilling and sprays mitigate - Respirator use when required Monitoring - Personal gas detectors - Area monitoring stations - Regular air quality testing
