METHOD FOR PREPARING ORE BODIES IN DEPOSITS FOR LEACHING USEFUL COMPONENTS Russian patent published in 2008 - IPC E21B43/28 E21C41/16 

Abstract RU 2327864 C1

FIELD: mining.

SUBSTANCE: invention relates to geotechnology and can be used in subterranean leaching the metals and ores, particularly to preparing ore bodies in deposit for leaching. The method includes the explosive loosening the ore deposits and supplying the process liquor. Explosion of the blast hole rings (11) is performed to shake the central solid of the ore body, and in the upper ore body, the peripheral perforations with branching cracks (10) are formed by pin-point explosion, to inject solutions.

EFFECT: invention provides even pattern sprinkling of the solid, even distribution of the leaching solution in its size at the minimal volume of preparatory first workings without ore shrinkage.
