摘要
滑坡是露天矿中一种常见和重大的灾害,是影响矿山安全生产的重要因素,因此对露天矿边坡稳定性评价有重要的现实意义.在建立露天矿三维地质模型的基础上,对地质模型进行切割产生任意位置剖面;根据边坡实时监测数据自动生成岩移监测曲线和滑坡预警线,根据曲线确定可能发生滑坡区域,在三维地质模型的相应位置切割剖面,作为边坡稳定性计算的依据;采用Bishop法和剩余推力法两种方法计算边坡稳定性系数,进而评价露天矿的边坡稳定性.
Landslide is a common and important disaster in open-pit;it is the important factor of mine safety production,therefore,to evaluate the slope stability of open-pit is of important practical significance. On the basis of constructing 3D geological model of open-pit,the model is cut to produce random position profile. According to the real-time monitoring data of slope,rock movement monitoring curves and landslide warning-line can be produced automatically. According to the curves,the area where may take place landslide is determined,and profile will be cut on 3D geological model in corresponding position. It can be used in the slope stability calculation. Bishop method and the residual thrust method are adopted to calculate stability factor of slope,and then the stability of open-pit slope is evaluated.
