The primary operations required in underground are rock breakage an d material handling. If the target is sufficiently soft (e.g., coal and rock salt), mechanical excavation utilizing continuous miners, shearers, ploughs/plows, and so on, can be employed. In contrast, drilling and blasting are usually employed when the ore is too hard for cutting.
