摘　　要：以安太堡矿在相似模拟下端帮开采不同长度下边坡稳定性为研究对象,研究端帮开采对边坡稳定性影响,结果表明:随着开采长度的增大,位于留设煤柱上方的覆岩下沉逐渐放缓且缓慢达到稳定状态;在采掘长度的加大下,坡体内部覆岩沉降也在不断加大,直到沉降影响到地表,使地表逐渐失去支撑形成塌陷。In order to study the influence of the end mining on the slope stability, studied the stability of slope slope at different lengths of Antaibao mine in similar simulation. The results showed that： with the increase of mining length, the subsurface subsidence above the coal pillar is gradually slowing down and gradually reaching a steady state. Inside the excavation length increase downhill body of strata subsidence is also increasing, until the settlement of influence to the surface ,to gradually lost support form the surface subsidence.
