摘要： According to embodiments described in the specification, an exemplary method is disclosed for hydraulically hoisting potash (or other evaporite ore) ‘fines’ material from an underground mine. The method includes mining an ore deposit using a boring machine to generate Run-of-Mine (ROM) material at a mine face, conveying the generated ROM material to an underground ore screening plant, screening the ROM material relative to a threshold size wherein the threshold size is a feed size of one or more flotation cells at a surface processing plant, mixing ‘fines’ material, comprising ROM material that is below the threshold size, with a saturated brine to create a slurry mixture wherein the saturated brine prevents the ‘fines’ material from dissolving into the slurry mixture, and pumping the slurry mixture to a surface location via one of a shaft and a borehole to the surface product separation plant.

摘要： Enhanced method for borehole mining comprising: drilling a borehole using a low-frequency pulsing sonic, hydraulic mining system including a pulsed jet assembly; inserting casing into the borehole above target deposit depth; inserting and rotating assembly into the casing with a sub-coupling and a shoe rock bit positioned below the casing; pumping fluid into the borehole; evaluating slurry at surface; fracturing and disaggregating materials at target deposit with pulsing jets from the sub-coupling and rock bit causing light slurry to flow upwardly to the annulus between the borehole casing and the downhole assembly, then upwardly through the annulus to the surface of the borehole thereby causing heavy slurry to concentrate in a sump, located below the pulse jet rock bit; continuing to form cavity at target location; removing pulsed jet assembly from borehole; running core barrel to extract heavy slurry from sump; analyzing slurry to determine whether to continue with operation.

摘要： In-situ solution mining method of an ore bed, particularly containing trona, which comprises exposing to a solvent an ore region inside a borehole drilled in the ore, and dissolving a desired solute within the exposed region to provide a liquor and create a voided ‘undercut’, such undercutting making the ore susceptible to gravitational loading and crushing. Unexposed ore falls into the undercut by gravity without breaking the ore roof resulting in exposure of fresh ore to the solvent and in preventing solvent exposure to contaminating material near the roof. The desired solute is eventually dissolved away in the entire bed from its floor up to its roof. Solvent injection may be delivered through a conduit positioned inside the borehole, and may be moved by retracting or perforating the conduit. The method may employ an advancing undercut initiated up-dip and traveling down-dip, or a retreating undercut initiated down-dip and traveling up-dip.

摘要： A downhole mixing tool and method for removing sand and other debris from a wellbore which combines the sand with a treatment fluid so that the sand is lifted to the surface of the well for removal. The tool includes a chamber into which the sand laden fluid is drawn and the treatment fluid is introduced. Ports into the chamber are arranged to provide a pressure drop to draw the sand laden fluid into the chamber and a mixing time within the chamber before sand laden fluid of lower viscosity exits the chamber to travel to the surface. Additional features include blades on the tool for breaking up obstructions prior to being drawn into the chamber and a lubricating line through the tool to introduce lubricating fluid to the blades.

摘要： 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.

摘要： A method and apparatus for the hydraulic removal of bitumen from a tar sand deposit comprises forming a borehole into the tar sand deposit and securing a casing into the borehole. Into the casing is inserted a mining tool having a water/diluent channel and a slurry exit channel. Through the casing the borehole is charged with crushed aggregate. At the lower end of the tool are nozzles through which high pressure hot water/diluent is injected as a jet from the water/diluent channel into the tar sand deposit causing a cavity to form in the tar sand deposit. The heat of the water/diluent jets and dissolving action of the diluent softens the tar sand contacted and the impact of the jets and the scouring action of the aggregate, as impinged upon by the jets, removes the tar sand from the surface of the developing cavity into a water phase. A bitumen/diluent phase rises to the surface of the water phase and is removed from the cavity through the casing. A water sand slurry at the bottom of the developing cavity is removed from the slurry exit channel where sand is subsequently removed and the water is recovered and reintroduced back into the process along with makeup water and diluent. Water temperature and pressures are controlled to optimize the hydraulic mining process.
