FIELD: mining.
SUBSTANCE: invention relates to mining industry and is intended for underground leaching of metals from ores and technogenic mineral formations. Method of combined development of ore involves extraction of rich ore to surface, enrichment of rich ores, filling mined space with disintegrated filling consisting of rejects of rich ore and ordinary ore enrichment, leaching of metals from filling materials. Prior to leaching rejects of rich ore enrichment are granulated with addition of cement and water, activated by ultrasound for 8-10 minutes, at frequency of 2.0-2.2*104 Hz, with further maturing of granules for 20-22 days.
EFFECT: technical result is increase of efficiency of development, as well as reduced ecological harm to environment.
