A conveying installation that is positionable over an oblique slope of an opencast mine pit may be used to convey raw materials from a lower height level on an extraction level of the opencast mine to an upper height level at a ground level adjacent to the opencast mine pit. At least one conveying container can be loaded with raw materials at the lower height level and unloaded at the upper height level. At least one bearing cable for load-bearing and control and one traction cable for moving the conveying container may be provided. At least at the upper height level, a support element may be disposed, to which the bearing cable is attached and on which the traction cable is guided.

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.

The present invention relates to a method of storing waste material in a subterranean formation, the method including digging a mine shaft to reach the subterranean formation; constructing a ventilated underground control center wherein the center includes a computerized control panel; providing a drill head, wherein the computerized control panel controls the movements of the drill head; providing a hollow drill pipe; providing a movable hydraulic shield; providing a movable resin roof bolting machine; providing a movable waste extrusion device; operating the computerized control panel to advance the drill head into the subterranean formation to obtain a mined-out space; and extruding waste material into the mined-out space of the subterranean formation.

A continuous actuator driven material handling system for raising and lowering bins in a vertical or inclined shaft, comprising: a first pair of actuator assemblies, each of the first pair of actuator assemblies configured to alternately raise a first bin by increments; a second pair of actuators assemblies, each of the second pair of actuator assemblies configured to alternately lower a second bin by increments; a further plurality of first pairs of actuator assemblies mounted on a wall of the shaft to thereby successively raise the first bin up the shaft; and, a further plurality of second pairs of actuator assemblies mounted on the wall of the shaft to thereby successively lower the second bin down the shaft.
