• Equipment Selection for Surface Mining: A Review

    The process for creating a borrow-pit is sequential: rst explosives loosen the earth; then, exca-vating equipment removes small vertical layers (or benches) of material, as illustrated in Figure 1. Over time, these benches themselves are blasted, excavated and removed, making the borrow-pit wider and deeper.
