摘　　要：露天矿山边坡普遍存在稳定性安全隐患,为分析某露天钼矿采场边坡稳定性,采用现场勘察及数值模拟的方法,对该采场不良地质条件及边坡稳定性进行研究。结果表明:采场部分区域存在渗水点、裂缝、坍塌等不良地质条件,采场东帮边坡水位线较高,地下水是影响边坡稳定的主要因素;采场边坡整体较为稳定,局部区域存在隐患,采用边坡雷达及GNSS监测设备形成双重动态实时监测系统,对边坡进行全天候实时监测,预报滑坡灾害,为矿山安全生产保驾护航。There are generally hidden safety hazards in the slope of open-pit mines.In order to analyze the slope stability of an open-pit molybdenum mine,the adverse geological conditions and slope stability of the stope were studied by means of field investigation and numerical simulation.The results show that there are some bad geological conditions such as seepage points,cracks and collapse in some areas of the stope.The water level line of the east slope of the stope is high,and groundwater is the main factor affecting the stability of the slope.The slope of the stope is relatively stable as a whole,and there are hidden dangers in some areas.The slope radar and GNSS monitoring equipment are used to form a dual dynamic real-time monitoring system,which can monitor the slope in real time all day and predict the landslide disaster,so as to escort the safe production of the mine.
