中文摘要：
为研究在露天煤矿岩质边坡下开采对边坡稳定性的影响,以阜新矿区某露天煤矿边坡为研究对象,采用相似材料模拟进行边坡下充填开采的研究,并使用有限元软ADINA建立三维模型,采用有限元折减法计算了未开采、全陷开采和充填开采边坡的安全系数。研究表明,充填开采后边坡的安全系数明显大于全陷开采的安全系数,充填开采能有效地控制露天矿岩质边坡的移动和变形,边坡的位移值沿坡脚向坡顶方向逐渐减小,对边坡稳定影响较大的因素为坡顶边缘位置的水平移动和水平变形,在露天煤矿岩质边坡下进行充填开采是切实可行的。
英文摘要：
In order to study the influence of open pit mining on the stability of rock slope, taking the slope of a surface mine in Fuxin as the research object, the backfill mining under the slope was sim- ulated using similar material experiments. A three-dimensional model was established using the finite element software ADINA, and the safety factors of the slopes of untapped, full-subsidence and back- fill mining were calculated using the finite element reduction method. The analysis results show that the safety factor of the backfill mining was significantly larger than that of the full-subsidence min- ing; that the backfill mining can effectively control the displacement and deformation of the rock slope of open pit ; that the displacement of the slope decreases gradually from the toe to the top ; that the horizontal displacement and deformation of the edge of slope top have most influence on the sta- bility of the slope. The backfill mining under the rock slope of open pit is feasible.
