The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip mining.
102 the demand of coal in the year 17 was estimated 884.87 MT whereas the domestic availability of coal was estimated 724.71 MT. Here, the gap of 160.16 MT was projected to meet through the imports (Satyanarayana et al. ). In this regards, open cast mining technology can play a vital role to full fill the demand of estimated coal production.handling Extraction and first treatment of solid fossil ,The primary emission of firedamp is believed to occur during the extraction of deep mine coal. Open cast mining, since it involves the extraction of coal seams close to the surface and the handling and storage of coal, are not considered to be as important. In many cases, firedamp is actively removed from the coalfield by various methods, normally
