Evaluation of Open Pit Mine Slope Stability Analysis

The issues concerned with slope stability in the open cast mines have come to forefront in the mining operations due to increasing pit depth. The cut slope stability has the most prominent influence in the productivity and longevity of a mine, collapse of which can lead enormous damages to man and machinery. It is always considered as economic burden to mine production. A comprehensive study is necessitated to ensure stable slopes which are aided by numerical, analytical, physical, kinematic and empirical analyses. In the present study four cut slopes from a coal mine in Wardha Valley Coal field have been analyzed using empirical and kinematic tools. The study has involved the classification and prediction the probable failure mode of the slope mass using slope mass rating and kinematic analysis. The analysis results have matched well with the field observations and can help to protect the slope and ensure the safety for better productivity.
