VIBRATION-PROOF BLASTING METHOD WHICH MINIMIZES BLASTING VIBRATION TRANSMITTED TO THE GROUND OR STRUCTURES

摘要

PURPOSE: A vibration-proof blasting method is provided to improve vibration reducing effects because a vibration-proof area is established adjacent to a blasting area.;CONSTITUTION: A vibration-proof blasting method comprises the steps of: boring a plurality of vibration-proof holes between a blasting area and a protection area to set a vibration-proof area(S30,S40), injecting expansible mortar in a portion or all of the vibration-proof holes and solidifying the extensible mortar so that the hydration reaction of the extensible mortar makes the vibration transmission characteristic of the vibration-proof area different from that of an adjacent area(S60), and implementing blasting in the blasting area(S70).;COPYRIGHT KIPO 2012
