【Abstract】 The charging structure and action principle of the pressure-relieved and vibration-insulated blasting were introduced.In the same conditions,earthquake effect model tests and production tests of the pressure-relieved and vibration-insulated blasting,smooth blasting,and conventional blasting were carried out.The results show the vibration velocity of the pressure-relieved and vibration-insulated blasting was lower than ones of other two blasting methods,Better isolation material of the pressure-relieved and vibration-insulated blasting are better and bigger air interval of the bore-hole bottom in the reasonable scope make reducing vibration effect better.更多还原
