METHOD FOR MULTIPOINT INITIATION OF EXPLOSIVE CHARGES Russian patent published in 2010 - IPC F42D3/04

Abstract SU 1840797 A1

FIELD: blasting.

SUBSTANCE: breaking is carried out by arrangement of initiator in the form of trotyl block garland, which are periodically repeated on detonating cord for the whole length of column charge and are arranged on the side of charge wall external versus damaged massif, besides distance between trotyl blocks along initiator length equals 2 diametres of charge.

EFFECT: invention makes it possible to improve extent of rocks crushing by development of dynamic initiation in direction of blasted unit ledge slope.
