Abstract: An improvement to a sonic drilling system comprising a high-pressure, high-volume water pump connected to a fluid supply and a length of casing in a borehole; an elastic sonic rod string; an eductor coupling having an upwardly directed convergent nozzle; a transition rod; a sub-coupling having a laterally directed convergent nozzle; and a shoe rock bit having a downwardly directed convergent nozzle. The water pump provides fluid down the bore of the sonic rod string, the eductor, the transition rod, the sub-coupling and the rock bit whereby adjustable high-pressure, high-volume fluid is forced through the sonic rod string, the eductor, the transition rod, the sub-coupling and the rock bit to fracture, cut and agitate targeted mineral into slurry and whereby the light slurry is directed effectively upwardly through the annulus to the surface for extraction and heavy slurry gravitates into a sump trap and is recovered with a core barrel.

Abstract: 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.

Abstract: 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.

Abstract: An adjustable dynamic, removable, mechanical foot leverage orthotic system is disclosed having a plate member positioned on top of one or more fulcrum member that are placed inside of a shoe. The plate is free to move within the shoe about the fulcrum to provide the wearer with mechanical improvement of abnormal, functional and associated foot pathology and can directly and indirectly effect the entire gait cycle. The foot leverage system can be integrated into the shoe design or can be inserted within a conventional shoe to create a foot leverage system. Methods of use and treatment are disclosed for the treatment of pes planus, pes cavus and tendonitis. The foot leverage system may also be used with the disclosed foot mapping system and method.
