Opencast mining technology results in the release of a huge amount of air borne dust. The air borne dust peculiarly below 100 micron in size, are environmentally nuisance and cause health hazards. Total suspended particulate matter (TSPM) and respiratory particulate mater (PM10) are the major pollutants in the air environment of opencast coal mines. Therefore, dust generation, its dispersion, and pollution load assessment have been found to be major concer4ns in air quality modeling of opencast coal mines. The present paper focuses on the quantification of sourcewise emission inventory for different point, area and line sources considering the background dust concentration at one of opencast coal project (OCP), nakmely Hindustan Lalpet of Western Coalfields Limited (WCL). The 24 hr average concentrations of TSPM and PM10 were monitored at three monitoring stations during winter season. On an average the PM10 concentration in the ambient air constituted 17.00 to 60.3% of TSPM concentration. TSPM concentration ranged from 313.11 to 565.57 µg/m3 and 79.48 to 270.61 µg/m3.
