摘要：Breaking of sandstone or other rocks overlying coal seams as well as coal seams in opencast coal minesis essentially required for ease in excavation. The process of breaking rocks normally involves drilling and blasting.Coal mining industry world over, for all its importance and contribution to the energy sector, is viewed with scepticismfor its impacts on environment and society. Apart from other processes, blasting of rocks with explosives is a majorcontributor to originate several evils of coal mining like emission of noxious gases, high speed dust and fly rocks, heat,and noise and ground vibrations. Moreover, what miners get after blasting is rock wastes, lumpy coal and sometimesquality of coal also gets deteriorated due to mixing of rock wastes in blasted coal. Waste dumps also create long-termenvironmental problems. This paper develops a new methodology to generate sustainable value in opencast coal miningsignificantly increasing the inextricably-linked demand of production systems, by way of designing blast-free opencastcoal mines. Mechanical method of cutting and breaking the overlying rocks and coal seams as well can replace theprevalent practice of blasting with explosives. An experiment of the designed method has been conducted using locallymade simple tools and a comparative study was made to examine the benefits of the design over the prevalent practice.The method is found socio-eco-effective, economically viable and provides new business opportunity. There appearssubstantial prospect for applicability of the design in coal mining industry, and it deserves a high potential to become abrand CSR practice on the industry to benefit the society and improve sustainability.
