摘　　要：为了判断某矿七号坑南扩时爆破振动对边坡的影响,采用ANSYS有限元软件建立数值计算模型,输入实测爆破振动数据,模拟爆破振动作用下边坡的动态响应。研究结果表明:正常生产爆破振动引起的边坡应力和变形很小,边坡总体稳定;正常生产爆破荷载下边坡不会出现塑性区贯通,说明爆破后边坡整体不会受破坏,仍处于稳定状态。研究结论可为接续下来的南扩常规生产爆破作业提供依据。In order to judge the influence of blasting vibration on the slope when one mine No.7 pit is expanded to the south,an ANSYS finite element software is used to establish a numerical calculation model,input the measured blasting vibration data,and simulate the dynamic response of the slope under the action of blasting vibration.The results show that the slope stress and deformation caused by the blasting vibration of normal production are very small,and the slope is generally stable;The plastic zone penetration will not appear on the lower slope of the normal production blasting load,indicating that the slope after blasting will not be damaged and is still in a stable state.The research results provide a basis for subsequent normal production blasting operations.
