Slope failure is a common problem in opencast mines which occur because of improper design. So it is important to monitor and analyze the stability of slope on a regular basis. Stability analysis of slopes is associated with the various opencast mining operations throughout the life cycle of the project, and it is very necessary to analyze the slope on a regular basis. Mining activities involve risk at each working stage and slope stability is an integral part of the open pit or opencast mines as the whole operation process depends on the slope stability. In the mining industry, opencast mines give higher production as compare to underground mine. So it is very important to maintain the stability of the slope in a proper way, and the design of slope should be in such a way so that the slope will be able to bear the different activities going on there. Slope stability analysis is used in a wide variety of geotechnical engineering issues, including, but not limited to, the following problems: 1. To Determine the stable cut and fill slopes, 2. To Assess the overall stability of retaining walls, including different stability measures (includes permanent and temporary systems), 3. To assess the overall stability of shallow and deep foundations for structures situated on slopes or over potentially unstable soils, 4. Stability assessment of various landslides (mechanisms of failure, and to determine the design properties through back-analysis), and to develop the mitigation techniques to improve stability. In this present research various software is used for the numerical modelling e.g. – FLAC slope, OASYS to generate the different models to analyze the stability of the slope. Based on different numerical models after using FLAC and OASYS, comparative studies have been carried out for the Factor of safety.
