MATRIX WITH AN INTERRUPTED DETONATION CIRCUIT CHANNEL Russian patent published in 2022 - IPC F42B3/10 

FIELD: explosive technology.

SUBSTANCE: invention relates to explosive technology and can be used in the development of means to improve the safety of explosive devices (ED) by interrupting the detonation circuit (DC) with a guarantee of maintaining a high level of reliability of the ED. A matrix with an interrupted detonation circuit channel contains an explosive composition and an inert layer covering it. In the matrix and the covering inert layer, cavities (grooves) are made along the sides of the channel and under it with the formation of a bridge in the inert layer. In one of the side cavities there is a knife with a flat rectangular or concave profiled end, the larger side of which exceeds the adjacent size: the height of the bridge.

EFFECT: possibility of interrupting the DC channel, ensuring explosion safety during the interruption.
