  • Patent number: 11492904
    Abstract: Disclosed are systems and methods to bore or tunnel through various geologies in an autonomous or substantially autonomous manner including one or more non-contact boring elements that direct energy at the bore face to remove material from the bore face through fracture, spallation, and removal of the material. Systems can automatically execute methods to control a set of boring parameters that affect the flux of energy directed at the bore face. Systems can further automatically execute the methods to: monitor, direct, maintain, and/or adjust a set of boring controls, including for example a standoff distance between the system and the bore face, a temperature of exhaust gases directed at the bore face, a removal rate of material from the bore face, and/or a thermal or topological characterization of the bore face during boring operations.

  • Patent number: 11008846
    Abstract: A water jet borehole mining system controlled and operated aboveground 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 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 water jet borehole mining pipe which serves as the conveyor of the system. The mining pipe is used to transport a high-pressure stream of 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 disaggregated and slurrified resource to the surface. The mining pipe transports the slurry via airlift, fluid eduction or a combination of both.

  • Publication number: 20080179061
    Abstract: A system, apparatus and method for abrasive jet fluid cutting. An abrasive jet fluid cutting nozzle assembly comprises a hose 49 for receiving an abrasive jet cutting fluid; a helix/spring 40 rotatably attached inside the high pressure hose 49; and a nozzle 46 connected to the hose 49. The helix/spring 40 is tapered such that the turn ratio of the helix 40 varies from the proximate end to the distal end. The rotation of the helix 40 creates a vortex and increases the pressure of an abrasive jet cutting fluid as it passes from the proximate end to the distal end. The disclosed subject matter further includes a system and method for using the abrasive jet fluid cutting nozzle assembly.

  • Publication number: 20080036268
    Abstract: The present invention includes a hydro-shearing apparatus, a hydro-shearing system, and a method of mining waste coal. The hydro-shearing apparatus includes a fluid supply line adapted to permit the transporting of fluid, a nozzle adapted to emit the fluid, a pump adapted to recover at least the fluid, and a fluid discharge line adapted to permit the transporting of at least the fluid. The method may include positioning the hydro-shearing apparatus at least fifty feet away from a high wall of waste coal, manipulating the hydro-shearing apparatus to a vertical position within twenty feet of the top of the high wall of waste coal, operating the hydro-shearing apparatus such that a fluid stream contacts waste coal material, recovering the coal product with the pump of the hydro-shearing apparatus, and transporting the coal product away from the hydro-shearing apparatus.

  • Patent number: 7270195
    Abstract: Material is removed from a body of material, e.g. to create a bore hole, by plasma channel drilling. High voltage, high energy, rapid rise time electrical pulses are delivered many times per second to an electrode assembly in contact with the material body to generate therein elongate plasma channels which expand rapidly following electrical breakdown of the material causing the material to fracture and fragment.

  • Patent number: 7178598
    Abstract: A device for a hydraulic cutting tool (30) for cutting of at least one pipe (16, 18, 20) or tubular object beneath a water floor (10), wherein the cutting is carried out from a surface facility (2). The cutting tool (30) is anchored in a pressure tight manner in the pipe (16), whereupon pressurised gas (86) is pumped into a pipe section (80) immediately below the cutting tool (30). With this, liquid (8), and eventually pressurised gas (86), will flow out of the pipe section (80) via a short drain pipe (66) through the cutting tool (30), so as to create a gas filled pipe volume (90) comprising the relevant cutting depth (32) in the pipe section (80). The invention differs from prior art by the outflowing liquid being led onwards up to the surface facility (2) via a drain line (92). The upper end portion of the drain line (92) is connected to at least one adjustable choke device (102, 104).

  • Patent number: 7114583
    Abstract: An orbital tool apparatus and method of using the apparatus for boring, drilling, reaming, and cutting having a tool housing, a tool collar located within the housing, the tool housing having the ability to couple to a conduit structure, fluid orbiting jets within the tool collar, and a tool funnel located below the tool collar and within a lower portion of the tool housing. The orbital tool creating a bore in a surface, when fluid flowing into the orbital tool via a conduit is directed out of the orbital tool towards the structure, a portion of the fluid flowing within the orbital tool being diverted through the fluid orbiting jets causing the diverted fluid to impinge against the tool funnel, causing the tool funnel to oscillate creating a sweeping flow towards the surface.

  • Patent number: 7080888
    Abstract: A dual nozzle hydro-demolition system is mounted on a robot vehicle having a tower, with the robot vehicle and tower permitting the device to be positioned in any desired location on a vertical wall surface. The robot vehicle includes a plurality of tires and a motive power system allowing it to be moved to a desired location. Bearing pads are mounted on jacks allowing the tires of the robot vehicle to be elevated slightly off the ground to preclude undesired movements. A carriage is slidably mounted on a beam and carries dual nozzles, each of which is connected to a supply of high pressure water via a heavy duty hose. The nozzles are rotated using a hydraulic motor. A coupling is provided within the flow circuit from the source of water to the nozzle allowing a conduit adjacent the nozzle to rotate with respect to a conduit receiving water from the source thereof, so that each nozzle can be rotated without any water leakage.

  • Patent number: 6877930
    Abstract: A method for working a concrete surface uses a water jet ejected from a nozzle of a nozzle holder. The nozzle holder reciprocates in cutting sweeps and moves together with a working apparatus in steps between the cutting sweeps. The water jet is directed in directions of the sweeps, and at the end of each sweep, the nozzle holder is swung into a new angle of attack for a subsequent cutting sweep. At the end of a cutting sweep, the nozzle holder begins to swing backwards simultaneously as its linear velocity increases to permit the target area to remain substantially unchanged at the start of the stepping of the working apparatus so that the water jet makes a cut forwardly in the stepping direction. The stepping and change of angle of attack are completed simultaneously immediately prior to the commencement of a subsequent cutting sweep.
