摘　　要：根据矿岩爆破理论和爆炸应力波在矿岩与胶结充填体异质界面上产生折射与反射的原理 ,提出的小药包短空气间隔控制爆破技术成功地解决了安庆铜矿高阶段矿柱回采爆破对两侧尾砂胶结充填体造成破坏而导致充填体失稳的技术难题 。In light of the theory of orerock blast and the principle of the refraction and reflection of explosion stress wave on the heterogenous interface between orerock and cemented fill,a technique of small charge and short air interval controllblast was introduced so as to solve the technical problem of fillmass unstability which occured when the cemented tailings fill of both sides were damaged by the blast of high level pillar mining,and realized the safe recovery of high level pillars.
