The comparative The first public sector coal company under central study of air pollution in near working quarry, control was “NATIONAL COAL Dhanpuri open cast mine falls in to be sheet no.

Sampling of appropriate physical, chemical and biotechnological respirable particulate matter in the ambient air, interventions. Destruction of the environment is often determination of its concentration and comparison an unfortunate consequence of mining industry. In could be done.[1] There is a lot of pollution created by mineral processing, however, recovering a fraction of huge coal mines and its effects are well observed in the mined material above the cutoff grade and the people living there. The sample collected and discarding the rest as waste cannot help but have an analysed by different methods, and the data comes adverse impact on the environment.[3] The out is foremost for the identification and comparison environmental challenges from coal mining include of the basic problem. All the parameters show that coal mine accidents, land subsidence, damage to the both mines are polluted in terms of air. The results water environment, mining waste disposal and air and graphs represent the comparative variation in pollution. These are either environmental pollution or three months, on the basis of the observation carried landscape change. A conceptual framework for out. The observed values shows that the air sample solving mine environmental issue is proposed.[4] carried a lot of pollution and on the basis of which it Open cast mine and underground mining dominates conclude that Dhanpuri open cast mine is more coal production in India. A survey was conducted to polluted than Bangwar underground mine with evaluate its local atmospheric impact. Emission data respect to respirable particulate matter or PM10. were utilised to compute dust generation due to Although various safety measures are taken by the different mining activities work zone air quality, coal mines for the cleanliness of environment from ambient air quality seasonal variation are described air pollution as suggested by state pollution control revealing high pollution potential and consequent board which is appreciable, but here some useful impact on human health.[5] Air pollution from coal suggestions are given at the end of the research paper mines is mainly due to emission of particulate matter for the safety of environment and human health (SPM & RSPM) and gases like NOx and SOx.
