Overburden Dump Slope Stability: A Case Study At Coal Mine

Rai , Purna Bahadur and Mahapatro, Sudeep (2013) Overburden Dump Slope Stability: A Case Study At Coal Mine. BTech thesis.



Slope stability of overburden dumps plays as integral part of opencast mine project throughout the operation process. 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. The heavy machinery implanted for the extraction and transportation of wastes in the opencast mine whose management is of prime importance. The problems relating to overburden dump slope stability is catching attention for safe working in adverse natural constraints. This paper examines the influence of various parameters such as slope height, slope inclination, interfacial shearing resistance on the dump deposit. The analysis cover analysis of various sections of the waste dumps from the mine including material properties, strength values, bench height and angle. The evaluation of slope stability analyses in geotechnical analyses in geotechnical engineering has followed closely developments in soil and rock mechanics as a whole. Most of the design methods are purely based on field experience, followed by sound engineering judgment. During the last few decades, the concepts of slope stability analysis have emerged within the domain of rock and geotechnical engineering to address the problems of design and stability of dump slopes.
