Mar 20, 2021 Abstract. Coal is the cheapest source of energy, so the economic importance of coal is critical for an emerging economy like India. Although the benefit of coal is enjoyed by the entire nation, the environmental externalities and adverse health impacts are highly confined to the mining neighbourhood only. Moreover, mining regions in India are mostly located in the
