METHOD TO PREPARE ORE BODIES IN PLACE OF BEDDING TO LEACHING OF USEFUL COMPONENTS Russian patent published in 2013 - IPC E21B43/28 E21C41/16 C22B3/04

Abstract RU 2495238 C1

FIELD: mining.

SUBSTANCE: method to prepare ore bodies to leaching of useful components in place of bedding includes installation of charges into well rings (11) in the central part of the ore body, explosion of the specified well rings and subsequent injection of a process solution into the central part of the ore body via perforation channels with the branching cracks along periphery of channels, formed by the upper part of the ore body with directed blasting Charges are installed with formation of a water circular gap between an explosive charge, bottom and walls of the well, after formation of a circular gap the well is filled with water or plugged.

EFFECT: invention makes it possible to increase opening of wells and evenness of distribution of a leaching solution in the ore body volume.
