Abstract: Indian coals have high percentage of ash content. Bigger sizes are crushed into smaller ones and fed for washing. The main air pollution problem due to washery project is the dust, which is more acute than any other coal processing industry. It is, therefore, essential to pay attention to assess the impact on air environment due to washery activities. Air pollution problem in the washery in question was due to the superimposition of pollutants from the washery and a thermal power plant (TPP). To evaluate the actual contribution of air pollutants by washery and thermal power plant factal analysis techniques were adopted. Approach to the selection of air monitoring stations for factal analysis and methods adopted for air quality survey have been described. Three season data were generated and the status of air pollution has been evaluated. The data were critically analysed on the basis of changes in wind directions at different seasons, the proportion of ash and volatile matter in washery dust and TPP fly ash, and microscopic examination of the SPM by identification of black dust from the coal washery and whitish gray dust from power plant. From the data results the actual contribution of pollutants by the washery and thermal power plant were evaluated. The results obtained by different techniques were found to be comparable.
