One of the major problems associated with opencast mining is disposal of a large volume of overburden/waste material. Maximum possible waste material has to he accommodated within the de-coaled mine due to shortage of space for formation of external dump. Stability of these internal dumps govern the mining cost, safety and environment. Greater attention is therefore required to analyse the factors controlling the slope stability of waste dumps within quarry. This paper deals with the computer program which can identify the impact of different stabilizing and destabilizing forces (geo-technical, geological, hydro-geological and operational parameters) on the slope stability of internal damps formed by draglines.
