— 16. 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 (NOx, SO2, methane, CO2 and CO) and to regulate temperature. The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the …

— Ventilation control of dust in coal mines is important in the different types of underground coal mining such as (1) room and pillar mining, (2) longwall mining and (3) shaft mining. Type (1) is done in an ore deposit where some of the ore is left behind to form columns in the mine that prevents it from collapsing and it is used for coal mining.
