FIELD: mining.
SUBSTANCE: combined method of underground ore leaching involves dehydration of ore bodies, cutting of mine workings in them, construction of geotechnological wells, development of ore bodies by supplying and extracting the leaching and productive solutions from them. After mine workings are cut, they are flooded and development of ore bodies is performed in water-saturated conditions. Leaching solutions are supplied to one of ends of mine working and removed from the other end of the mine working; then, pumping of solutions from mine working is stopped by shutting-off the appropriate wells in order to direct the leaching solution to the geotechnological wells drilled to the horizon, through which the productive solution is pumped.
EFFECT: invention allows increasing the development efficiency, improving environmental situation on the territory, decreasing costs, reducing colmatation phenomena and increasing productive capacity of the development.
