• Underground mine ventilation Wikipedia

    Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove dust and noxious gases (typically NO x, SO 2, methane, CO 2 and CO) and to regulate temperature.The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself.

    MINE VENTILATION SYSTEMS

    MINE VENTILATION SYSTEMS Ventilation is the control of air movement, its amount, and direction. Although it contributes noth ing directly to the production phase of an operation, the lack of proper ventilation often will cause lower worker efficiency and decreased productivity, increased accident rates, and absenteeism.
