METHOD FOR WELL HYDRO-EXTRACTION OF MINERAL RESOURCES AND DEVICE FOR REALIZATION OF THE METHOD Russian patent published in 2007 - IPC E21C45/00 

FIELD: mining industry, geology, possible use for extraction of gravel, sedimentary, loose and semi-loose deposits of mineral resources.

SUBSTANCE: the method includes opening the formation of mineral resource by central and flanking wells, creating an extraction chamber by hydraulic destruction of mineral resource, sending hydraulic mixture to the surface. Directional shafts are constructed using flanking wells with direction of their faces towards hydro-extraction apparatus in central well, from which hydro-disruption is successively performed. Movement of disintegrated mineral resource is performed with usage of devices having screw conveyor-like differently oriented sections. Device for realization of the method comprises a hydro-extraction apparatus, in which a flow divider is installed connected to hydro-monitor and to overhanging support via bypass pipes. On the overhanging support, upper and lower independent motors are mounted in form of hydraulic motors, positioned one above the other concentrically relatively to the pipes column. The upper hydraulic motor is provided with screw conveyor section, oriented towards inside of hydro-mixture suction and lifting unit, and lower hydraulic motor is provided with rock-destroying tip with expander through screw conveyor-like section.

EFFECT: possible extraction of mineral resource with improved efficiency and productivity, due to better disintegration and movement thereof with minimal losses, and also reliable operation of hydro-extraction apparatus.
