A Review of Operations Research in Mine Planning

exposing the mining face, miners dug shafts and used ladders to retrieve the hard stone before backfilling the extracted areas to enforce stability in the excavated tunnels (Gregory 1980). Mining has five stages (1) prospecting, (2) explo-ration, (3) development, (4) exploitation, and (5) recla-mation. In the first phase, geologists use visual
