DEVICE FOR THE DETONATION WAVE FORMATION IN AN EXPLOSIVE SUBSTANCE CHARGE Russian patent published in 2018 - IPC F42B3/10 

FIELD: blasting operations.

SUBSTANCE: device for the detonation wave formation in an explosive substance charge (ES) refers to the area of blasting. Device includes an inert matrix with a detonation wiring made in the form of a network of detonation channels with a common input portion connected to the source of initiation with the portions located along the surface of the matrix, and end portions located at an angle to the surface and contacting directly with the blasting charge or with an additional layer disposed between the blasting charge and the matrix. On the surface of the matrix a different thickness overlay is installed, with a decrease in thickness from the center to the periphery, with a blind end hole for placing the common input section and grooves filled with ES connecting the common input section to the detonation wiring areas located along the surface of the matrix. In the case of an additional layer of ES, a sample is selected for its placement on the surface of the matrix facing the blasting charge.

EFFECT: invention makes it possible to ensure the synchronization of the onset of the detonation front in a blasted ES charge.
