Coal is the major source of power in India and world over. Coal mining is an essential industry which has a major role in the economic development of the country. Most major mining activities contribute directly or indirectly to air pollution. Coal dust is a major air pollutant which affects the personal working in the mines and also people residing in …
As it was noted by Kossovich et al. (2019b), the coal dust is a significant threat to the safety of people and to the environment because the fine coal dust particles whose sizes are less than 25 μm are able to stay in the air for a long period of time. These particles may also appear during mining, storage, transportation and processing of coals.
