| Summary: | PT XYZ is one of the coal mining companies operating in South Kalimantan Province. PT XYZ intends
to evaluate the stability of high wall and low wall slopes in the Life of Mine (LOM) design. This study
aims to determine the stability of the LOM design slope. The classification of whether the slope is safe
or not is based on the Minister of Energy and Mineral Resources Decree No. 1827K/30/MEM/2018 by
calculating the Safety Factor (SF) in static and dynamic conditions and calculating the Probability of
Failure (PoF). Based on the analysis results, the high wall and low wall slope is in a stable condition
with static FK ? 1.3, dynamic FK ? 1.5 and PK ? 5%. The results of the analysis showed that the
dynamic factor of safety, static factor of safety, and probability of failure of all the section is in
compliance to the Minister of Energy and Mineral Resources Decree No. 1827K/30/MEM/2018. |
