Mining companies are increasingly being challenged to improve energy efficiency, as a method of reducing both the cost and environmental impact of their operations. The haulage activity at an openpit mine represents a large proportion of total energy consumption.
An innovative technological approach to skip haulage could optimize costs and energy efficiency in hard rock mines. By Dr. Franz Wolpers. Openpit metal mines are often shaped like an inverted cone, with the ore and overburden being drilled and blasted, then loaded and transported by shovelandtruck systems.
