Abstract.

A mechanism of detonation transmission between explosive cartridges in a divided charge is analyzed in this article. Influence of a channel diameter on outflow speed of detonation products is considered. Critical conditions of detonation transmission between divided cartridges are determined. Different constructions of the blast-hole charges providing detonation transmission between the explosive cartridges in a divided charge are proposed.

Keywords:

explosive, transmission of detonation, products of explosion, breaking of detonation.
