METHOD FOR INSTALLATION OF BLASTING NETWORK OF SERIES OF OUTBURST CHARGES Russian patent published in 2000 - IPC

Abstract RU 2151373 C1

FIELD: blasting, in particular, methods for blasting, applicable in digging of canals, trenches, foundation ditches in rocks. SUBSTANCE: the method consists in placement of charges in rock masses, installation of live primers in charges, installation of blasting network with detonating cord and detonation from the detonating cap. The distinction is in the fact that the detonating cap is connected to the middle of the detonating cord, whose ends are connected to the middles of the additional detonating cords between the charge live primers. Besides, the ends of the additional detonating cords are connected to the middles of the second group of detonating cords connecting in pairs the live primers. Besides, the live primers are interconnected by a duplicating detonating cord. EFFECT: reduced labour content of preparation of rock mass to outburst. 3 cl, 4 dwg
