摘　　要：露井联采模式一般用于开采浅部煤层或矿床,以往的研究主要侧重于对露天开采下边坡的稳定研究,而对涉及井工开采问题的研究重视程度不够。本文从联采对露天边坡破坏特征分析的角度,分析不同井工开开采部位下边坡的破坏过程,并优化其开采顺序。现场实践证明,本文提出的开采顺序是合理的。The combined model of open-pit with underground mine are generally adopted to exploit shallow coal seam or mineral deposit, precious studies are mainly focused on the stability of the slope under open-pit mining, and the research on the problems due to underground mining is attached less importance to. This paper analyses the failure process of the slope under different underground mining sequence from the angle of analysis of the slope failure feature due to combining mining, and the mining order is optimized, filed practice proves that the mining sequence put forward in this paper is reasonable.
