METHOD FOR MECHANIZED CHARGING OF FLOODED DEEP-HOLES WITH FLUID EXPLOSIVES

摘要

FIELD: mining art, applicable for formation of deep-hole charges at blasting operations on surface minings. SUBSTANCE: at an approach of the upper level of the charge column to the elevation of the intermediate detonator the charge hose is lifted above the intermediate detonator, explosive is fed to the deep-hole without lifting of the charge hose, and at an entry of the hose is continued at a rate of deep-hole filling. EFFECT: enhanced reliability of fixing of detonating cord to intermediate detonators in the column of deep-hole charge.
