摘要

FIELD: mining. ^ SUBSTANCE: invention relates to mining and can be employed at development of deposits of minerals in form of an edge seam overlapped with mass of rocks of basic sediments by means of borehole hydraulic mining. The method of hydraulic borehole mining incorporates opening out a rock mass overlaying a producing horizon with a vertical borehole; then a successive boring of several producing inclined wells is performed out of this borehole in several directions along the pitch at a hanging wall, then up and down washing out of the horizon of deposits is carried out from producing wells, and as a hydraulic borehole device goes up, a case column is taken out; before termination of borehole washing out a required safety massif of rock is left at the upper portion of the borehole. ^ EFFECT: increased efficiency of hydraulic borehole mining of minerals and increased output owing to extension of development zone. ^ 7 dwg
