    3 innovative dust control measures for open-pit mines

    These control measures will prevent coarser dust (10 microns and larger) from becoming airborne and will reduce overall dust throughout an open-pit mine. However, low pressure watering does not actively subdue dust particles that are already airborne or respirable sized dust particles which are less than 10 microns (PM10 dust).
