BLASTING METHOD USING BLAST PRESSURE INDUCTION CONTROL DEVICE, AND BLAST PRESSURE INDUCTION DEVICE APPLIED TO THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a blasting method using an innovative control device for blast pressure induction, by which when a blasting operation is performed at the outermost hole of a tunnel or a wayside or wall surface of a structure constructed at a location in which an adjacent structure of a downtown area is located, a transfer path of the blast pressure is controlled using the control device for the blast pressure induction so that the blast pressure does not exceed a proposed blast line, but is limitedly transferred into only a blasting area, and by which a smooth and elegant blasted surface is secured, and simultaneously, an over-break is prevented and vibration and noise are minimized, and to provide a control device for the blast pressure induction which is applied to the method.;SOLUTION: Since a general inexpensive explosive is loaded into a blast pressure shield cover 110 and easily utilized, the general inexpensive explosive can be replaced with an existing expensive precision explosive to significantly reduce blasting costs and improve blasting efficiency, thereby having a large economic impact and useful effects.;COPYRIGHT: (C)2012,JPO&INPIT
