BLASTING MAT FOR VIBRATION AND NOISE REDUCTION USING A COVER MEMBER SHUTTING A PLURALITY OF BLASTING HOLES

摘要

PURPOSE: A blasting mat for vibration and noise reduction is provided to prevent the leakage of explosion pressure and scattering stone by covering a plurality of blasting holes.;CONSTITUTION: A blasting mat for vibration and noise reduction comprises a cover member(13) and an elastic member(14). The cover member made of damping alloy covers a blasting section including a plurality of blasting holes to transform the vibration and noises caused by explosion through conversion into thermal energy. The elastic member is attached to the lower periphery of the cover member in order to prevent the leakage of explosion pressure and scattering stone.;COPYRIGHT KIPO 2010
