PROCESSES AND CONFIGURATIONS FOR SUBTERRANEAN RESOURCE EXTRACTION
Processes and configurations for subterranean resource extraction are provided. The processes include installing borehole strings, such as by drilling a plurality of boreholes, for example, first and second boreholes, that extend from a surface region into a resource deposit. The first and second boreholes are situated adjacent to each other. Portions of the first and second boreholes laterally extend in a penannularly fashion and connect terminally at a nodal space situated within the resource deposit. Carrier fluid is injected from the surface along fluid paths defined by the boreholes to in situ leach resource materials from the resource deposit into the carrier fluid, and carrier fluid containing the resource materials is brought back to surface for resource extraction.

HYDRAULIC HOISTING OF POTASH AND OTHER EVAPORITE ORES
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.

ROTARY BORING MINING MACHINE INERTIAL STEERING SYSTEM
A mining system with an inertial guidance system configured to enable precise excavation of geological material without a need to advance a survey line over a long distance and/or nonlinear excavation path, thereby maximizing productivity of the mind by minimizing a width of un-mined material necessary for support between adjacent excavation paths and minimizing equipment downtime.
