The present invention relates to a blasting method applied to civil works, comprising the steps of: forming a dust-proof area by puncturing a plurality of vacuum holes between a blasting area and a protection area; injecting inflatable mortar into a part or all of the plurality of vacuum- Curing the expandable mortar so that the vibration transfer characteristic of the vibration damping zone is differentiated from the vibration transmission characteristic of the adjacent zone by the hydration reaction of the expandable mortar, and advancing the blasting in the blasting zone Can be accomplished by a blasting technique. According to the present invention, the blasting vibration transmitted to the ground or the structure at the adjacent position in the blasting operation can be minimized, so that the blasting method can be applied to the construction site more widely, and stable construction can be performed. |
