Jul 21, 2016· Underground mining is the process of extracting minerals and ores that are located too far underground to be mined efficiently using surface mining methods. The primary objective of underground mining is to extract ore safely and economically while minimizing handling of waste rock. Typically, underground mine has less environmental impact.
underground mining equipment is specialized and expensive. A number of surface mines operate 24 hours/da y and almost 365 days/year in order to use open pit machinery for as many hours as possible, thereby reducing the number of machines required. In contrast, underground operations are often interrupted by the need
