Dump slope stability analysis

Abstract

In this modern world mining has become an integral part of our life. Mining activities effect in generation of both economic and noneconomic materials. The noneconomic materials are stored at selected places known as waste dumps. The stability of the waste dump has been of a matter of great concern over the years. The problems increases with limiting availability of land. In this project work the slope stability analysis is carried out for the waste dump of a selected iron ore open cast mine. In this process samples are collected and tests are carried out on these samples to get different geotechnical parameters. The factor of safety of different sections of the existing design of the selected mine are calculated by the help of GALENA software. In the end new design of dump slope are proposed by optimising the bench dimensions and material properties by the help of back analysis of GALENA. Then conclusion and various recommendation are given on the basis of new design of the dump slope.
