Shaft sinking has been and still is one of the biggest bottlenecks in any mining operation. Consequently, the shaft is by far the most expensive and time-consuming excavation of any development program. When the shaft-sinking problem is broken up into its components, it is found that shaft mucking represents the largest fraction, both costwise and timewise. Since the mucking operation is the most important part of shaft sinking, it is, then, the most logical place for the introduction of cheaper methods.
