Underground mine ventilation  Wikipedia

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.
