Feb 12, 2021 Automation may make mines 30 efficient and is set to contribute most in hard-rock mining, he noted. As mines get deeper, ventilation to support human operators becomes increasingly challenging and costly, material needs to be shifted and time is needed to get it above ground. Low digitalization.
Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals such as those containing metals like gold, copper, zinc, nickel and lead or gems such as diamonds. In contrast soft rock mining refers to excavation of softer minerals such as coal, or oil sands. Accessing underground ore can be achieved.
