Mining Methods
The excavating process in open pit mines result in cone-shaped volume in which the bench area becomes progressively smaller as the pit deepens with the walls formed by cascading benches (Fig. 2.1a). The flat surface of the bench remaining on the pit wall is called the berm (Fig. 2.1b). The berms create safe zones in case of rocks spalling away from the walls …
