摘要
为研究大直径深孔采矿法矿柱回采爆破对相邻矿房充填体的地震效应，应用一维应力波理论计算了安庆铜矿1＃矿桂边孔爆破对相邻3＃矿房充填体交界面施加的动载荷，计算结果与爆破试验结果极为吻合，为安庆铜矿大直径深了乙爆破的参数选择提供了科学依据。
In the study on the seismic effect from the blasting in the recovery of ore pillars in the large-diameter longhole mining on the fillbody adjacent to the room,the theory of one dimension stress wave was used to calculate the dynamic load from the periphery-hole blasting of 1# ore pillar in Anqing copper mine,which was imposed on the interface of fiIlbody adjacent to 3# room. The result of calculation well conformed with that of blasting test. A scientific reference was provided for the correct selection of large-diameter longhole blasting parameters.
