MINING: The mining of potash can be done by two methods, namely underground shaft mining and solution mining. Underground shaft mining involves digging underground tunnels to extract the potassium ores from the Earth's surface. The ores collected in the underground tunnels are transported to the surface either by manual labor or conveyor belts.

The purpose of this chapter is to gain a better understanding of the different underground scenarios in terms of mining methods, layouts and associated excavation geometries.

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 …
