2016-10-12  Most Rajamandala Limestone mining is performed in open-pit. Slope stability is often a major issue in an open-pit mine. The stability of the open-pit mine slope must be maintained so as not to disrupt the mining process. Rock Mass Rating (RMR) has been widely used as a method of classifying the strength of the rock mass.

The assessment of slope stability and rock excavatability

2016-10-27  The slope stability analysis of rocks is vital for designing safe slopes in open–pit mines. A proper slope design not only leads to improvements in slope stability and safety but also reduces costs, extends the life of mines and decreases the stripping ratio (Bye and Bell, 2001, Naghadehi et al., 2011).
