摘　　要：通过数值和相似材料模拟2种方法对露井联采下露天边坡的破坏过程进行了研究,结果显示,露天边坡的破坏是一个渐进的过程,决定开采安全的主要因素为露天与地下开采的边界垂直安全高度.并通过相似模拟试验分析,提出了地下开采的安全开采顺序.Through two methods of numerical simulation and similar simulation, the failure problems of the openpit slope under the condition of combining open-pit mining with underground mining were analyzed and discussed. The results show that the failure of the open-pit slope is a gradual process, in order to guarantee the normal open-pit mine production works well, the explored boundary must be controlled well by the vertical stature of safe mining. By the analysis of the similar simulation, the mining order is optimized.
