摘　　要：以平朔矿区平面露井协采工程实践为背景,采用相似材料模拟实验和数值分析相结合的方法对露井协采边坡变形破坏机理进行了研究,分析了顺坡开采和逆坡开采对边坡变形破坏影响的差异性。综合研究认为,顺坡开采方式不但能够提高煤炭资源采出率,而且在保证边坡稳定方面更加有利。研究成果为条件类似矿井露井协采时空关系优化奠定了基础。Taking the underground and open-pit combining mining as background, applying analogy simulation and numerical simula- tion to researching slope deformation and failure mechanism. Difference of slope deformation and failure between slope mining and in- verse-slope mining was analyzed. It was obtained that slope mining not only could improve coal mining ratio, but also was favorable for slope stability. This research provided basis for optimizing time-space relationship of underground and open-pit combing mining with similar conditions.
