摘要(Abstract)：

采用FLAC3D3.0数值模拟软件,对巷道围岩在自然应力状态下和爆破振动荷载作用下巷道的围岩应力场、变形场和塑性区的状况及其变化特征,进行了计算机数值模拟。得到了采矿巷道的应力场和变形场,根据结果对比分析得出深孔爆破振动荷载对巷道围岩的影响及其特点。
By the FLAC-3D numerical simulation software,the conditions and its changes of stress,deformation and plastic zone of tunnel were simulated in natural stress state and under blasting vibration loading to obtain the stress field and deformation field.According to the comparative analysis of results,the impacts and characteristis of blasting vibration on surrounding tunnel rock by deep-hole blasting were obtained.
