Abstract: The increasing trend of opencast coal mining tends to release huge amount of dust. But there is no well defined method of estimating dust emission due to coal mining activities This paper examines the sources of dust emission due to coal mining activities and focuses on the quantification of dust emission with the use of emission factors or prediction type equations. Because of site-specific nature, emission factors developed for one site may not give the correct results for another site. In the present investigation prediction equations are utilized for the development of emission factors and they are used for the quantification of dust generation due to opencast coal mining. For the applications of this concept one large opencast coal project of Bharat Coking Coal Ltd (BCCL) was investigated and the amount of dust emitted due to different mining activities was quantified. This paper also focuses on the significance of this study in the field of environmental protection and likely impacts of such study. The paper concludes that once the amount of dust generation is estimated, the impact on air quality can be assessed appropriately and a proper air pollution control strategy can be developed.
