EXPLOSIVE DEVICE Russian patent published in 2014 - IPC F42B3/10 

FIELD: blasting operations.

SUBSTANCE: explosive device comprises the main explosive charge, the detonation wave generator in the form of a matrix of inert material with a network of channels and openings with the common receiving part, filled explosive charges and coated, the source of initiation initiating the common receiving part. The matrix of the detonation wave generator is made of open-porous heat-resistant material having the property of sorption of explosive charge melt and free removal of gaseous products of decomposition of explosive charges. The matrix of detonation wave generator can be made of open-porous technical carbon material with nanopores, or of open-porous alumina with the porosity of 20 to 50%. The matrix material comprises explosive reagent chemically active reactive with respect to the melt and/or gaseous products of decomposition of explosive charge capable of reducing the rate of decomposition of explosive charges and its thermal effect.

EFFECT: increase in fire and explosion safety of explosive devices with detonation wave generator; preventing unwanted distribution of melt of explosive charges beyond the explosive device; providing thermal decomposition of explosive charges without acceleration, resulting in a flash, with reduction of the gaseous products of decomposition beyond the detonation wave generator.
