A borehole subsurface mining system and methods for generating sonically pulsed hydraulic jets for subsurface excavation and slurry extraction, combining modulated oscillating energy at relatively low frequencies produced from a sonic drill head of working sonic core drilling rigs in combination with energy and water flow from a pressurized pumping system, to perform pulsed jet slurry mining of underground resource deposits through at least one partially cased subterranean borehole using a sonic drill head member and rod string members in relation to which the attached inventive pulsed jetting apparatus and methods operate. The system design and methods includes an adaptably attachable, sectional, tubular combination apparatus assembly with at least one casing member in general axial alignment comprised of sonic rod, jetting educator coupling, transition rod, jetting sub-coupling and jetting shoe rock bit members. Also includes methods for sump heavy concentrate core barrel extraction and for optimizing high density slurry extraction. |

1) A sonically pulsed hydraulic jetting system assembly intended to be used with a commercial sonic drill rig with movable tower attachments for subterranean modulated low-frequency (equal to or less than 300 Hz) for sonically pulsed jet borehole mining having a sonic drill head, wherein the sonic drill head can be securely attached to a relatively elastic sonic rod, to which the system is attached and functions when adaptably attached by hydraulic conduit to a high pressure high volume operating pump system with a water reservoir, and within a borehole that is at least partially cased, comprising:
a. At least one or more transition rod members that is generally tubular having a top end for attachment to the bottom end of a sonic drill rod, in tubular fluid communication with the sonic drill string functioning to minimize stress between the sonic drill water flow stream and the sonically pulsed hydraulic jetting system assembly by applying additional weight to the system as well as by incorporating in its internal structure such as guide vanes to reduce flow turbulence supporting the sub-coupling nozzles to generate more coherent sonically pulsed jetting bolts, having a bottom end for attachment to the pulsed jetting sub-coupling; b. At least one or more sub-coupling members that is generally tubular with one or more convergent-type nozzles, e.g. quartic with guide vanes, directed laterally for pulsed jetting with a top end attached to a transition rod or may also be otherwise attached to a sonic drill rod directly and a bottom end attached to a pulsing rock bit or may be manufactured to incorporate the structures of the shoe rock bit, so that the sub-coupling member may have qualities of all three components of the system assembly structurally incorporated into one sonically pulsed jetting system and rock bit apparatus attached to the bottom end of a sonic rod string, but is preferably a separate sonic jet mining component for increased variability; c. a sonically jet pulsing shoe rock bit member having at least one downwardly directed convergent pulsing jetting nozzle to cut and agitate rock and slurry relative to a sump member oriented beneath the sonically pulsed jetting system assembly and having one or more crushing plates or wedges to crushingly fragment large rock fragments or boulders by moving the rod string and attached rock shoe bit with at least one downwardly pulsing jet, up and down and in rotation to generate rock-fracturing torque and compression force from the sonic drilling rig as well as by using the immediately oriented jet pulsing effect, having a top end for secure attachment to a sonically pulsed jetting sub-coupling; d. at least one or more sonically pulsed eductor coupling members being substantially aligned in the sonic rod string, attaching a sonic rod above and a sonic rod below, having one or more sonically pulsed jetting nozzles directed upwardly, having associated partial chambers to be used for eductor siphon function, used within the annulus in association with sonic casing and hydraulic gradient forces generated within the mining cavity to facilitate lifting of slurry through the annulus to the surface; e. an elastic sonic rod or rod string that is adaptably attached on its top end to a sonic rod attached to a spindle of a sonic drill head that oscillates at a low frequency (usually less than or equal to 300 Hz) facilitating pulsing energy transfer into a high-pressure high-volume fluid column moving through the tubular sonic rod open-ended hydraulic system that will include in fluidic tubular communication at least one rod with a sonically pulsed hydraulic jetting system assembly, that includes a pulsed jetting eductor coupling, transition rod, pulsed jetting sub-coupling and pulsed jetting shoe rock bit or any combination, for receiving high-pressure and high volume fluid flow from a pump member with at least one check valve as well as simultaneously transferring adjustably tunable oscillating energy from a sonic drill head member through its spindle with sonic energy wave transfer through and from the elastic (generally meaning to be deformable but not deformed permanently) sonic rod or sonic rod string and its fluid column generating pulsed water jets through the eductor coupling's one or more jetting nozzles into the fluid filled annulus from the interfaced internal fluidic column, also resulting in pulsed fluid volume streaming from the sonically pulsed rock shoe bit and sub-coupling nozzles; f. a sonic casing member or combination string of sonic casing members, elastic or inelastic, to be used for emplacement in the ground, with adding or subtracting casing sections to a casing string and recovery by a sonic drill rig and secured to the surface but independent of the sonic drilling rods, used to facilitate slurry extraction using at least one sonically jetting eductor coupling member positioned within the casing's internal space in tubular attachment and alignment with at least one sonic drill rod, facilitating the benefit of sonically jet pulsed mining using the sonically pulsed hydraulic jetting system assembly plan and methods, having its top most end usually above the surface of the ground, its bottom end oriented above or within proximity of the subsurface mining targeted mineral. g. a water pump member with a driver and conduit attachments allowing for communication of fluid to drill head member and sonically pulsed hydraulic jetting system assembly, presenting continuous flow high-pressure and high volume capabilities, preferably with automatic adjustment capabilities to adjust pressure and volume to jet mining variable demands, usually functioning on average per mining site between 200 psig and 2000 psig, and with a flow capacity between 20 gallons and 2000 gallons of water per minute depending upon and being variable with the objectives attached to the pulsed jet mining operation, though these are only estimations of pumping parameter required using various situational constraints by equipment and are not intended to be limiting but representing a common effective range for applying the sonically pulsed hydraulic jetting system assembly to perform subsurface mining production of slurry from a targeted mineral source with efficiency, but specific parameters will be dictated by the analysis and constraints of each mining site's situation and logistics; h. a sonically pulsed jetting borehole mining system combining high-volume fluidic column's hydraulic energy from a surface pumping member as well as simultaneously transferring of relatively low-frequency sonic oscillation energy waves from a sonic drill head member into an attached inelastic or elastic sonic rod or rod string that interfaces with a pressurized water column and attachable sonic pulsed jet mining apparatus generating a subsurface sonically pulsed jetting mining system and methods, to be called Hice Hydro-mining. |
