SMR was used effectively to evaluate the stability of an opencast coal mine slope in India (Pradhan et al. 2011). The case study presented in this paper pertains to a limestone deposit situated in the Himalayan region of Northern India, which was proposed to be developed as an opencast mine to feed limestone to the nearby proposed cement …

The stability of rock slopes in an opencast limestone mine throughout the mining process was investigated using the limit equilibrium approach (SlopeW). The optimal excavation method with a substantially steeper slope angle of 450 rather than 350 was successfully accomplished at the critical geological section of the pit slope under …

The nature and orientation of joints in rock strata affect the damage pattern under explosive loading. Most of the limestone deposits in India are found with severity of joints. Categorically, these joints may have variable orientations such as dipping out of the blast face, inside the face, horizontally or having strike parallel to the face. The damage …

The slope type of the platform is a rocky antidip slope. The slope rock mass is mainly limestone, followed by mudstone. The foot of the slope is an accumulation of limestone mining debris, and the slope on the east side of the step is mainly covered by the accumulation of gravel and the overburden of mine restoration treatment.

Consideration of external or support loads: The effect of external loads or support added to the slope must be taken into consideration. The external loads may be static (e.g., a structure founded on the top of the slope) or dynamic (e.g., the impact of an earthquake) and must be incorporated in the model as they affect a slope's FoS.

Slope instability of open-pit mines has adverse impacts on the overall mine profitability, safety and environment. The slope of an open-pit mine is crucially influenced by the slope geometry, quality of rock mass and presence of geological features and their properties. The objective of this study is to demonstrate a method to select the optimal …
