Abstract

Presents the emission factors of the twelve open cast mining activities, identified as the most significant sources of air pollution in and around the mining areas. The Pasquil and Gifford formula has been used to compute the emission rates for the ground level emission. The findings of the study reveal that haul roads and transport roads are contributing maximum of SPM concentration among all other mining activities. The total emission rate of the haul roads and transport roads is 2.3749g/s, whereas the grand total of the emission rate from overall mining activities is 25.7117 g/s. Moreover, it is found that the emission rates of NOx and SO2 are very negligible, which are only 0.7813 g/s and 1.2785 g/s, respectively. The emission rates of SPM NOx and SO2 due to overall mining activities of the open cast mining are compared through a pie diagram, Finally, the study concludes that the SPM is the major problem of an open cast mining and it can be controlled through immediate short-term and long term biological control measures
