FIELD: mining.
SUBSTANCE: invention relates to mining and can be used at mining operations. Proposed method comprises drilling the row of test wells to fit downhole hydromining units therein and to washout minerals therefrom by fluid jets forced by said units for pulp to be delivered to surface. Drilled pipes are inclined in the plane perpendicular to spread of said row. Wells are drilled in a row to distance equal to double efficient length of washout jet while rows are spaced apart through distance equal to efficient length of washout jet. Washout is performed from wells towards hanging layer to form the face with hemispherical cross-section perpendicular to well axis.
EFFECT: reliable egress of minerals, washout at dried face.
