摘要(Abstract)：

介绍了定向卸压隔振爆破的装药结构和作用原理,在相同条件下,进行了定向卸压隔振爆破、光面爆破、常规爆破的地震效应模型试验和生产试验。结果表明,定向卸压隔振爆破的振速比其他爆破方法低,且隔振材料越好、在合理范围内孔底空气间隔越大,降振效果越好。
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.
