| 摘 要： | 矿产资源的开采, 有些是按地下与露天复合开采方式进行。依据采区的空间对应关系, 两种采动影响域中的一部分相互重叠, 导致采动效应相互作用和相互叠加, 从而组成一个复合动态系统, 因此边坡岩体变形机理更加复杂, 与单一露天开采相比有较大的差异；然而, 过去在处理此类问题时近似地应用单一露天采动影响下的分析方法, 结果与实际情况存在一定差异；本文在理论分析的基础上, 推导出边坡稳定性的评价方法, 为此类矿山后续采矿设计及安全生产提供科学依据。

| Abstract: | In the course of ore mining, there is often a situation of combined underground and open pit minings. According to the relation between spatial positions of stopes, parts the influenced realms by different mining excavations are overlapping. It results in the interaction and superimposition of two kinds of mining effect and hence forms a composite dynamic system. Thus, the deformation mechanism of slope rockmass becomes more complicated and differs from that caused only by open pit mining. However, in treatment of the conventional method for slope stability, this kind of influence is usually used. Its result was different from the real situation. Therefore, in this paper an evaluating method is derived on the basis of theoretical analysis and case study. It provides scientific basis for design and safe production of these mines with continuous excavation. |
