Dragline controlled opencast mining is the most productive way of winning coal for opencast mines connected to power plants in the Indian opencast mining scenario, accounting for 40-45 percent of overall opencast coal output. Dragline dump and shovel-dumper dump involves in the formation of the overburden dump in dragline-operated opencast mines. The dragline dump comes from parting between bottom-most seam and just above to bottom-most seam. Whereas, the shovel-dump dump comes from parting between intermediate seams and top overburden above upper seams. The optimum distance between the toes of the shovel-dumper and dragline dumps is planned by site-specific geotechnical parameters of the dump material, mine floor inclination, water profile inside the dump mass, seismicity/blast vibration impact, geometry of dragline dump and shovel-dumper dump. BIT Mesra completed a R&D study, using the above geo-engineering criteria; establish guidance for predicting the optimum distance between the toe of a dragline dump and that of a shovel-dumper dump. The outcome of this study is discussed in this paper.
