    • A hydraulic borehole mining system controlled and operated above-ground includes a high-pressure cutting nozzle that is delivered to an underground resource body through a relatively small diameter borehole. A series of water and air fluid streams at various pressures are delivered to the resource body, and the target resource is disaggregated and/or fluidized and conveyed back to surface via the hydraulic borehole mining pipe which serves as the conveyor of the system. The mining pipe is used to transport a high-pressure stream of combined air and water fluids that have been directed and aligned into laminar flow to a focused water jet cutting head. The central bore of the mining pipe brings the slurrified resource to the surface. The mining pipe transports the slurry via hydraulic airlift, fluid eduction or both.
    • 在地面上控制和操作的液压钻孔采矿系统包括高压切割喷嘴,其通过相对小直径的钻孔输送到地下资源体。 一系列在各种压力下的水和空气流体流被输送到资源体,并且目标资源被分解和/或流化并经由作为系统输送机的液压井眼采矿管道返回到表面。 采矿管道用于运输已经引导和排列成层流的聚合空气和水流体的高压流到聚焦的水射流切割头。 采矿管的中心孔将石油资源带到地面。 采矿管道通过液压空运,液体排放或两者运输浆料。
