DETONATION SYSTEM OF A NON-ELECTRIC DETONATOR USING A SPARK IGNITION DEVICE AND A BLASTING CONSTRUCTION METHOD USING THE SAME WITHOUT AN EXPENSIVE SIGNAL TUBE

摘要

PURPOSE: A detonation system of a non-electric detonator using a spark ignition device and a blasting construction method using the same are provided to reduce the generation of waste plastic signal tubes and obtain electric stability.;CONSTITUTION: A blasting method using a detonation system of a non-electric detonator using a spark ignition device(300) is as follows. The spark ignition device is connected to a signal tube(400) of a non-electric detonator connected to a tunnel face(500). A leading wire(200) of hundreds of meters is connected to the spark ignition device and hidden to a safety distance. Disconnection, short circuit, and normal condition of a blasting circuit are inspected on the leading wire using a circuit tester(50-1) or a resistance measuring instrument(50-2). When determining the blasting circuit is in the normal condition, the leading wire is connected to an electric blasting machine to start blasting.;COPYRIGHT KIPO 2012
