Abstract

Disclosed is a hydraulic hoisting system for moving material from an underground position to a surface level. In most cases, the system will be used to move fragmented rock or ore generated during the normal operation of a mine to a position on or near the surface of the Earth so that the rock or ore can be further processed. The system is a conduit loop for continuous flow of circulating fluid from near or at the surface to underground; a slurry preparation unit for mixing the material with a portion of the fluid to form a slurry; and an injection unit for injecting the slurry into the conduit.
