摘　　要：露天矿边坡是露天开采活动的产物,随着开采的不段深入,很多露天矿转为露天井工联合开采,其开采安伞性成为亟待解决的课题。本文以某露天煤矿的边坡下开采为工程背景,采用相似材料模拟试验与数值模拟计算相结合的方法研究了开采安全性。研究表明:所研究剖面的开采巷道围岩处于不稳定状态,且相似材料模拟试验结果与数值计算结果吻合,该研究叮为实际工程的安全可靠性提供一定的参考。The high and cliffy is the result of opencast working. A lot of mine can not be opencast worked any more after many years mining, and the safety of the mining becomes a important problem. Based on a real project, exploiting under the slope of a open-pit, the stability of the surrounding rockmass was analyzed by the similar material test and the numerical simulation. Both similar material experimentation and numerical simulation are based on the actal excavating scheme. In ordr to forecast the hidden safety trouble, the two result are compared integrating the actual data. The study showed that the surrounding rock of profile was not steady, and the result of the two method was similar with each other.
