FIELD: mining.
SUBSTANCE: invention relates to mining industry, in particular, to blasting of rocks and ores. Method of breakdown of rocks and ores by hydroexplosion involves drilling of wells, formation of explosive charges, placing explosive charges in well in a shell, filling clearance with water, initiation and blasting of charges. Formation of distributed packaged explosive charges is performed outside well, reinforced on two threads of detonating cord, charge is placed into a shell, wherein in bottom part of well to lower cartridge of charge is fixed a load – metal cylinder with diameter smaller than well diameter, shell is filled with water.
EFFECT: higher efficiency of hydroexplosion, improved quality of crushing rock mass and reduced consumption of explosives.
