Mine Ventilation

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 NOx, SO2, methane, CO2 and CO) and to regulate temperature.Ventilation in underground mines is required to dilute and remove hazardous substances, control the thermal environment, and provide oxygen for humans and engine combustion. In Canadian mines, the most common considerations are the control of diesel engine exhaust emissions and mineral dust concentrations, to within prescribed levels for humans to work in that environment. A lesser concern is the clearance of blast fumes which is normally when the mine is not occupied. In a smaller number of mine radiation and other gases, such as methane may also need consideration. A new and increasing concern as Canadian mines go deeper is the control of heat exposure to the degree that it requires more air to control the temperature of the working environment than is needed for other concerns.
