dc.description.abstractThis thesis work focuses on the stability of slope in Open-Pit mining and the Factor of Safety of the slope. Slope failure can cause fatalities, and the number of failures has recently increased. Proper planning and analysis of slope stability are essential in ensuring safe and efficient mining operations. This paper covers the terminology of Open-Pit mining slopes and bench parameters, and discusses designing stable slopes for economic and safety reasons. The thesis work aims to optimize slope stability planning in Open-Pit mining operations through a case study using FLAC3D software. A numerical simulation program used in the field of geotechnics and geomechanics to simulate the behavior of geological materials. In this report, case study will simulate an Open-Pit mining scenario, including geological layers of coal deposit under Mohr-Coulomb failure criteria. Then assigning mechanical properties to geological layers, excavating the Pit area, estimating the shear stress and the factor of safety. The results will analyze geo-mechanical properties of rock such as Cohesion and Angle of Internal friction with a Factor of Safety. The Factor of Safety calculations will reveal the need for modifications to improve stability. The paper will conclude by emphasizing the importance of geological knowledge, mechanical properties, and numerical modeling for safe and stable mining operations.
