摘　　要：以望儿山金矿一、二号井为例,对井筒在采空区塌落影响下的失稳破坏机理和影响因素进行了分析研究,利用有限单元方法,对井筒及采空区的现状进行模拟分析,得到采空区围岩的塑性区分布状况、应力场、位移场以及井壁上部的水平应力和水平位移状况。With No. 1 and No. 2 shaft in Wang＇ershan Gold Mine as cases, the paper analyzed the failure mechanism of shaft and the influence factors resulted from collapse of mined-out area. And the current situation of shafts and mined-out areas were simulated numerically by the finite element numerical analysis method, which showed the distribution of surrounding roek＇s plastic zone in mined-out area, stress field, displacement field and the horizontal stress and displacement on the top of shaft lining.
