Abstract
Coal mining activities are increasing daily to meet the rapidly rising demand of power plant generation industry. As the coal mine is dug deeper below the current ground level, more quality minerals are being mined. Therefore, waste material stability is given significant attention in slope analysis for an economic and safety standpoint, and its instability is brought on by over-burden dump slopes, which puts people's lives at risk. This paper presents a case study on the slope stability analysis using Midas GTS-NX using the three types of soil, namely weathered soil, weathered rock, and bedrock. The study describes variation of factor of safety with various factors, such as slope height, soil friction angle, and diameter of the reinforcement bar using the Strength Reduction Method. The factor of safety increased after the dump was reinforced using the soil nailing technique, significantly affecting the dump's stability.Keywords: Slope stability, Factor of safety, Coal mining, Reinforcement, Midas GTS-NX
