摘　　要：针对露井联采矿井边坡稳定性差且影响因素多的实际情况,以国内某露天煤矿为工程背景,应用极限平衡和数值计算方法,首先将单一露天开采的边坡与露井联采边坡的稳定性进行对比研究,并对露井联采分为先露天后地下开采和露天与地下同时开采进行具体分析。研究表明,采空区的存在会降低边坡的稳定性,同时采空区最终的回采边界线的位置对整个边坡稳定性与资源采出率的影响是至关重要的。According to the poor mine slope stability of the surface and underground mining combination and the actual conditions of multi influence factors, taking a surface mine in China as the engineering background, the limit balance and numerical calculation method were applied to the comparison study on the stability between the slope in the single surface mining and the slope of the surface and underground mining combination. The paper had a certain analysis on the surface mining before the underground mining and the surface mining and underground mining simultaneously for the surface mining and underground mining combination. The study showed that the goal existed could reduce the stability of the slope and the location of the terminal mining boundary line in the goat： would be critical important to the whole slope stability and the resources mining recovery rate.
