摘　　要：针对深部开采竖井变形监测控制问题,利用有限元软件,对鲁中矿业集团公司小官庄铁矿深部开采引起的竖井井筒变形进行了分析,并采用倾斜仪和几何监测方法对竖井变形进行了监测,获得了大量的实测资料,通过与工程实际情况进行对比,二者趋于一致,从而证明了其有效性和合理性。The mineshaft deformation of Xiaoguanzhuang Iron Mine is calculated and analyzed with the Finite Element Analysis System in accordance with the influence of the rockmass displacements caused by pillarless sublevel caving method. In the light of mineshaft tilt due to deep underground mining, the shaft deformations are measured by using the tilt instrument and the geometric monitoring method. And a lot of data measured for shaft displacements and deformations are obtained.
