| 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. |
