Sections with ball clay was found to be less stable as compared to sections without ball clay.Copyright 2012Gemcom Software International Inc. The sections were incorporated into FLAC/Slope from the block model that was made in SURPAC. A total of five sections were considered to calculate the factor of safety with varying rock type. Followed by SURPAC, FLAC/Slope is used for calculation of factor of safety and numerical modelling of the slope. Volume calculation, reserve estimation and average grade calculation was done using the borehole data of the mine. SURPAC software was used to make the solid and block model. Beyond this safety factor, working would be difficult and risky and probability of failure will be more. A benchmark safety factor of 1.20 was set to consider the working conditions to be safe. The probability of failure of slope increases by increasing the overall slope angle of the working bench. A total of 50 benches has been considered in a single formation for calculation of factor of safety with varying overall slope angle. ![]() The working benches with height 3 m are very steep with individual bench slope angle varying from 80o to almost 90o. Case of Rajpardi Lignite Mine (GMDC) has been considered for this project. Factor of safety often calculated by the traditional deterministic analysis methods cannot exactly represent the stability of the slope. The factor of safety of the working slope has to be calculated and monitored from time to time so that safe working environment can be created and the slope can be avoided from failure. To avoid a slope from failure, working is to be carried out in accordance with the guidelines and safety standards. ![]() ![]() In open cast mining method, since it is the main focus as it contributes major portion of production, stability of the slope is of utmost importance. Mining is an arduous job and involve risk at each working stage. ![]()
