In view of the fact that Sijiaying Iron Mine does not have the condition of plane boundary expansion, it is necessary to set up the slope boundary pillar after the transition from open-pit to underground mining. The gravity increase method was adopted to study the stability of the slope boundary pillar after the transition from open-pit to underground mining. The evolution characteristics and laws of the stress field, displacement field and plastic zone of the slope boundary pillar under different gravity accelerations were obtained. The results show that under the condition of initial gravity acceleration of 1.0g, the 40 m thick slope boundary pillar can ensure the safety of underground mining and avoid instability of open-pit slope, such as collapse, caving and landslide. With the increase of gravity acceleration, the progressive instability failure of the slope boundary pillar can be divided into four stages: stable, slight deformation, serious deformation and instability failure. Slope boundary pillar is affected by the unloading of underground mining. The maximum principal stress is basically within 30 MPa, and the minimum principal stress and its distribution range increase greatly. The tensile stress value reaches more than 3 MPa, which is prone to tensile failure. The displacement field and plastic zone expansion characteristics of the slope boundary pillar are highly consistent with the tensile stress, expanding from the slope toe to the slope top on the west slope of the open pit. The research results have a certain guiding role in preventing and controlling slope instability after the transition from open-pit to underground mining.

针对司家营铁矿不具备平面扩界条件，露天转地下开采后需留设边坡境界矿柱的情况，采用重度增加法研究了该矿露天转地下开采后边坡境界矿柱的稳定性问题，得出不同重力加速度下边坡境界矿柱的应力场、位移场及塑性区的演化特征与规律。结果表明：在初始重力加速度为1.0g的条件下，留设40 m厚的边坡境界矿柱能够保证地下开采安全，避免露天边坡产生垮塌、冒落、滑坡等失稳现象；随着重力加速度的增加，边坡境界矿柱的渐进失稳破坏可划分为稳定、轻微变形、严重变形和失稳破坏4个阶段。边坡境界矿柱受地下开采卸荷的影响，最大主应力基本在30 MPa以内，最小主应力及其分布范围增幅较大，拉应力达到3 MPa以上，易产生张拉破坏；边坡境界矿柱的位移场及塑性区扩展特征与拉应力呈现高度一致性，由露天坑西侧边坡的坡脚向坡顶扩展。研究结果对矿山露天转地下开采后防控边坡失稳具有一定的指导作用。
