Abstract
The present invention relates to a blasting method using a control device for inducing a blast pressure, and a control device for inducing the blast pressure to apply the method. According to the blasting method using the control device for inducing the blast pressure, 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 inducing the blast pressure so that the blast pressure does not exceed a proposed blast line, but is limitedly transferred into only a blasting area. Thus, a smooth and elegant blasted surface may be secured, and simultaneously, an over-break may be prevented and vibration and noises may be minimized. According to the present invention, since a general inexpensive explosive is loaded into a blasting prevention cover and easily utilized, the general inexpensive explosive may 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.
