SPM is the Major Pollution in Open Cast Mining - A Case Study

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 emissions. 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 2.3749 g/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 NO_X and SO₂ are very negligible, which are only 0.7813 g/s and 1.2785 g/s, respectively. The emission rates of SPM, NO_X 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.
