INTRODUCTION TO MINING 1.1 MINING'S CONTRIBUTION TO CIVILIZATION Mining may well have been the second of humankind's earliest endeavors— granted that agriculture was the first. The two industries ranked together as the primary or basic industries of early civilization. Little has changed in the
the pit to the surface. Extraction occurs from benches (i.e., open faces of material). If prospectors deem the extraction of material in an open pit to be viable, they must determine both the pit design and the plan of operations. Pit design relies on preliminary analysis consisting of (1) an orebody model in which the deposit is discretized ...
