HIGH-ACCURACY RELAY FOR DELAY OF EXPLOSIVE PROCESSES Russian patent published in 2013 - IPC F42B3/16 F42C11/06

Abstract RU 2499976 C2

FIELD: blasting operations.

SUBSTANCE: high-accuracy relay for delay of explosive processes in delay-action blasting consists of a cover with a hatch, with a shock-action sensor arranged in the cover and galvanically connected to a power supply source of an electronic delay assembly having a waveguide holder-nut. The power supply source forms a current starting pulse of instantaneous electric detonators through the electronic delay assembly.

EFFECT: improving blasting time delay accuracy.
