Innovations: Introduction to Copper: Mining ExtractionUnderground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest underground copper mine. Open pit mining is employed when the orebodies are extensive, low in grade, and relatively near the surface, .
Underground Mining Transportation Systemsare major factors in the decision to use drifts and/or shafts for a mine. 2. From Surface to Underground/Vice Versa Considering transport systems from the surface to underground, mines may be classified into two basic egories; shallow mines with roadways of level or shallow gradients, and deep mines with vertical shafts or long inclined drifts.
