Large Scale Slope Stability in Open Pit Mining - A Review

The overall pit slope in an open pit mine, going from the pit bottom (toe of slope) to the crest of the pit, is made up of benches, interramp areas and haulage roads (Figure 1.1). Consequently, the maximum interramp angle is a function of the bench face angle, the bench height, and the width of the bench.
