The stageloader/crusher is the most significant dust-generating source in the headgate area. The breaking of coal and rock in the crusher generates large quantities of dust, which can mix with the ventilating airstream. The following practices can help control respirable dust levels in the stageloader/crusher area: Description of control:
Shut off the dust collector. Close the valve to the water line. ... After the material is extracted from a mine, the primary crusher ensures the rock is broken down into a size the secondary crusher can handle. Types of primary crushers include jaw, cone, gyratory and impact crushers.

Mining dust not only pollutes our environment and harms workers' physical health, but also accelerates abrasion and shortens the service life of jaw crusher. Therefore, it is very necessary and important to control dust.
The stageloader-crusher contributed an additional 0.5 to 0.9 Mg/m3 of dust to belt air, while the feeder-breaker contributed 0 to 0.2 Mg/m3 of dust. A 1,000-ft increase in belt entry length or a 200- to 500-st-per-shift increase in production resulted in roughly a 0.1-Mg/m3 increase in dust.
Respirable dust exposure has long been known to be a serious health threat to workers in many industries. In coal mining, overexposure to respirable coal mine dust can lead to coal workers' pneumoconiosis (CWP). CWP is a lung disease that can be disabling and fatal in its most severe form.
