摘　　要：资源枯竭矿井对工业广场煤柱的回收将不可避免地对井筒造成采动影响。文中分析总结了井筒采动变形破坏的影响因素,并结合地质采矿条件,对某矿工业广场煤柱采用条带矸石充填开采引起的井筒偏斜、竖向变形及径向变形进行了预计;分析了采动对井筒的影响;可为其他矿区井筒煤柱回采提供参考。It will make an inevitable impact on the shafts if the extraction and recovery of the industry square coal pil- lars continues by the resource - exhausted coal mines. This paper analyzes the influence factors of shaft deformation and damage caused by coal mining, and combined with coal mine＇s geological and mining conditions, it also pre- dicts the deformation of deflection, vertical deformation and radial deformation caused by strip and back filling min- ing method. Based on previous study, it analyzes the mining influence on the shaft and provides a reference for the similar coal pillar mining in other mines.
