Mines have air quality management plans in place to reduce the levels of dust they generate. Mining operations are planned and conducted to minimise disturbed areas and progressively rehabilitate mined areas; stockpiles are sprayed with water, and water carts keep unpaved roads damp so that dust generation is kept to a minimum.

Mining also leads to air pollution. For mining purposes, big machines are often used in order to make the mining process more effective and to reduce the physical work for miners. However, these machines emit large amounts of harmful gases, also including greenhouse gases like methane or CO2. Thus, mining can also cause air pollution and …
