Through a case study this paper depicts various innovative energy conservation opportunities in Open Cast Coal Mining. The research and development works are conducted in a particular Open Cast Coal Mine which belongs to Eastern Coal field Ltd(ECL), a subsidiary of Coal India Ltd (CIL), India. This paper will review the glimpse of methodology used and various energy conservation recommendations which are given in the Research and Developement project, followed by complete technical details of each and every recommendation. Mined coal transportation and coal handling plant are the two major energy intensive areas of opencast coal mining which are mainly emphasized in this endeavor. Finally, this paper concludes with the possible amount of energy savings with up-gradation of the mining system as per recommendations. It also indicates that the mine will also get huge monetary, safety and competitive advantages with the implementation of these energy conservation measures.
