Analysis of Slope Stability for Waste Dumps in a Mine

Abstract

In the civilized world mining activities are synonymous with the standard of life as well as the state of any nation. It results in both economic and uneconomic materials being generated. The Uneconomic materials (Wastes) are stacked at different places known as waste dumps. The stability of these dumps has been a major concern over the years. The problem becomes increasingly difficult with the reduced availability of land areas for dumping. In this project, the slope stability analysis for the waste dump of a local Iron Mine has been carried out. Samples are collected and tasted in the laboratory to find out different geotechnical parameters. The Factors of Safety of the various sections are calculated using Limit Equilibrium Method. Probabilistic analysis (Monte Carlo Simulation) has also been carried out to evaluate the stability of the existing design data. At the end bench design as well as corresponding safety factors has been developed based on the analysis.
