Quick Guide to Hard Rock Mining An Underground Miner

Quick Guide To Hard Rock Mining. Hard rock mining is a process that includes various techniques of excavating minerals from hard rock especially those that contain metals such as silver, gold, iron, zinc, copper, lead, tin, and nickel. This process also involves the same techniques while excavating large ore bodies containing gems such asWestern Australian underground hard rock mines. This was achieved through a comprehensive review of the issues affecting the diesel/electric LHD debate, as well as through the development of a parametric life cycle cost model. The results indicated that eLHDs are not yet a universal solution to all underground mining systems.Electric LHDs in Underground Hard Rock Mining: A Cost/Benefit
