METHOD FOR DEVELOPMENT OF SOLID ORE AND PREPARATION THEREOF FOR LEACHING Russian patent published in 2016 - IPC E21C41/22 F42D3/04 E21B43/28 

Abstract RU 2593668 C1

FIELD: mining.

SUBSTANCE: invention relates to technology of underground mining of ore deposits and can be used in mine for underground extraction and processing of ores. Method involves drilling blast holes, charging wells with explosive charges equipped containers with leaching solutions of reagents, ore breaking and cleaning of cutting products. Prior to development of next block in bottom part of mine face, vertical or inclined bore pits are drilled, and bore pits are charged with similar charges. In mass, located below level of development, cracks are formed, in which leaching solutions are injected.

EFFECT: improving efficiency of developing solid ore.
