Rock slope stability studies at selinsing gold mine, Pahang

Abstract

Rock slope stability has a tendency to slide or failure. Rock mass classification system has been proposed to reduce the risk of failure. Hence, the aim of this research is to do the preliminary assessment of rock stability via the rock mass classification system. Rock Mass Rating (RMR) system and Geological Strength Index (GSI) system are two main classification systems that have been chosen for these researches. As to achieve the objectives, necessary of several methods is required. This research testing divided into two categories which are field investigation (geological mapping) and software analysis. Field investigation are being done by settling the information by collected, measured, observed and recorded such as RQD, discontinuity orientation, spacing and condition. Lastly, the data obtained been entered into the software analysis Dips Rocsciences Software to generate the stereographic projection. Based on the researches result, the summation of all the RMR system and GSI system will determine the type of rock class while software analysis responds to failure of slope.
