Abstract

In this paper the stability analysis of an open pit slope of chromite mine in Odisha state, India has been evaluated with a present working depth of 147 m with 280 overall slope angle to deepening the pit to 182 m under critical geometrical conditions like limitation of area, and having two active internal dumps with a distance of 25 m from pit in north and south directions. The mine having 19 benches with a height and width of 8 m each, and the bench angle is less than 800 from horizontal. Open pit slope stability analysis has been performed using FLAC/SLOPE of numerical modeling technique. Thus by studying the factor of safety, the stability analysis of pit slope has been evaluated and suggestions based on the geotechnical studies and numerical analysis has been presented
