摘要
为了研究露井联采模式下边坡破坏和失稳机理,基于岩体力学分析和关键层理论,建立了露井联采边坡关键岩层耦合作用模式。研究认为在露井联采的条件下,露天矿边坡内部为砌体梁结构,大部分顺层滑坡的破坏都将经历表生改造、结构改造、时效变形和最终失稳4个阶段。
In order to study the mechanism of slope failure and instability under combined open-pit and underground mining mode, based on rock mechanics analysis and key stratum theory, the mine establishes a coupling model of key strata. Under combined open-pit and underground mining condition, the interior of the slope is masonry beam structure. Some slope evolution will undergo four stages： supergene transformation, structural modification, aging deformation and ultimate instability（deformation and stability）.
