    摘要： Method and apparatus for excavating and removing a settled body of discrete mineral solids (e.g., a tailings pond from a mining operation) by procedures which progress downwardly from the surface of the body. High pressure streams of liquid are traversed along a path in a pulping zone lowermost in first region of the body. The liquid forms a pumpable slurry with the mineral solids in the zone, and the slurry is then pumped from the zone leaving an undercut cavity sufficient to cause collapse of the overburden of solids. The collapsed overburden is then formed into additional pumpable slurry which is removed by pumping. Successive stages of excavation are carried out by moving the streams of liquid downwardly to a second region where the foregoing steps are repeated. In the apparatus a caisson is disposed vertically in the body and stabilized by means of a plurality of circumferentially positioned pilings. A plurality of high velocity nozzles are mounted in the caisson to direct liquid streams into a pulping zone surrounding the caisson. The slurry which is formed in the pulping zone flows through portals in the caisson into a slurry sump in the lower end of the caisson where a pump removes the slurry through a discharge line leading from the caisson. In one embodiment the caisson is fixedly secured to the caisson and jets are provided to direct liquid streams into regions below the lower ends of the caisson and pilings to sink the apparatus downwardly to the next lower region for additional stages of excavation. In another embodiment, the caisson is mounted for relative vertical movement with respect to stationary pilings.

    摘要： An hydraulic mining system comprising the generation of power from a column of water which downflows from a surface reservoir to an underground reservoir and in which at least a portion of spent water is recirculated and with the column of water operating a turbine, mechanically driving a pump included in a transfer tube extending from the mining level to the ground surface from the turbine, converting waste rock into slurry form, converting mineral-containing ore into slurry form, introducing the slurries into said tube to be pumped upwardly therein, separating water from said slurries at the ground surface and returning this spent water to the surface reservoir. In three embodiments, the mineral components of the ore are separated from the ore by micro-bacteriological processes and apparatus which includes a mill and a fermentation tank. In one of these embodiments, the separation is substantially completed at the mining level. In a second embodiment, it is initiated at the mining level, continued in the transfer tube and completed at the ground surface. In a third embodiment, it is carried out substantially at the ground surface.
