摘要

Open cast mining, which is a worldwide prominent mining technique, generates huge amounts of waste materials in the form of unstable dumps. The stability of these dump slopes is vital for mine operators, communities, and the environment. Failure of an unstable dump slope will lead to catastrophic landslides, environmental damage, loss of life, and economic disruptions. Waste dumps always have steep angled slopes as the waste has been tipped over from the top of the dump in a continuous and progressive manner. For new landfill, it is often desirable to design steep slopes as it can accommodate the maximum amount of waste possible. This research paper focuses on the analysis of dump slope stability in open cast mines, with the aid of SLIDE software. This study examines the influence of various parameters such as unit weight, cohesion, and friction angle on the dump slopes in different challenging ground conditions. This study covers analysis of various sections of the waste dumps from the mine including material properties, strength values, bench height, and angle using SLIDE 2D software. The final outcomes of the paper will help to a deeper understanding of dump slope stability and minimizes the risks associated with dump slope instability, ultimately fostering a safer and more sustainable mining industry.
