01.01.2014The most important emissions during coal mining and through active mine fires are particulate matter (PM), sulfur dioxide (SO2), nitrogen dioxide (NO2) and heavy metals. These air pollutants deteriorate air quality and ultimately affect the human health, flora and fauna in and around coal mining areas ( Singh et al., 1991)

In order to overcome these dangers, the Open Cast Projects have been developed. In addition to the advantage of safety, the manpower requirement in these projects is also less as compared to that for the underground mines. Machines only in Open Cast Mines carry out almost total work. The most vital operation in open cast coal mining is blasting.
