FIELD: mining.
SUBSTANCE: method of leaching payout bed includes exposing bed with rows of pressure and producing wells; additional inclined borehole is drilled form each main well of above said. Leaching is performed by means of supplying leaching solutions via pressure wells and withdrawing production solutions via producing wells. Additional inclined boreholes from pressure wells are drilled along the line of their row in one direction, while those from producing wells are drilled along the line of their row in the opposite direction.
EFFECT: increased efficiency of leaching and simplification of drilling process and equipment of wells.
