APPLICATION OF FACTAL ANALYSIS TO ASSESS OF AIR POLLUTANT EMISSION RATES IN OPENCAST COAL MINES-AN INNOVATIVE APPROACH

摘要

To maintain the energy demand, opencast mining has been growing at a phenomenon rate in India. However, it creates high air pollution problem within the work zone areas and disperses along with the wind. Regulatory requirements for air quality impact assessment are discussed. This paper examines the utility of air pollutant emission rates due to mining for evaluating the impact on environment and a large opencast coal project of BCCL was chosen for the study. The paper focuses on the use of emission factor data for the quantification of mine dust, development of factal analysis for the estimation of emission rates and their dispersion potential in the area. The study area was also being polluted by the surrounding industrial activities. It discusses the application of
