Air quality management: a mining perspective F. Schwegler Anglo Technical Division, South Africa Abstract Air quality management issues relating to mining are mainly centred around particulate impacts. These include dust deposition, and health impacts associated with PM10 and PM2.5 and the mineralogy and chemical composition of the particles.
Underground copper mining in Butte, Montana since the 1870's has resulted in over 49 miles of vertical shafts and 5,600 miles of horizontal workways. In 1955, high copper prices drove Anaconda Copper Mining Company to open a new pit mines including the Berkeley Pit.

Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts. As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of waste rock are removed from the pits and deposited in .
to fossil fuels, coal, and metal mining (Matthews et al., 2000:107). The amount of waste produced depends on the type of mineral extracted, as well as the size of the mine. Gold and silver are among the most wasteful metals, with more than 99 percent of ore extracted ending up as waste. By contrast, iron mining is less wasteful, with
In 1989, U. S.

Open-pit mining is to be considered one of the most dangerous sectors in the industrial world. It causes significant effects to miners health, as well as damage to the ecological land. Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths.
types of mining processes are underground mining and open-pit mining (surface mining or open cast mining). Probability of air pollution is high in case of open cast mining compared to underground mining. Present study carried out in open cast iron ore mining. Main pollutants emit from iron ore mine are particulate matter (PM 2.5, PM10), NO x, SO
