锦丰金矿露天矿边坡监测及滑坡预报

Open Pit Slope Monitoring and Slope Failure Predicting at Jinfeng Gold Mine

通过边坡日常巡查和对露天矿边坡进行动态、实时、连续自动监测,运用国内外滑坡动态预报的理论和方法,在滑坡地点、滑体形态与规模及滑坡发生时间三方面成功预报了2015年5月24日露天南部边坡多台阶滑坡。因在边坡滑坡前撤出了影响范围内所有的人员与设备,避免了人员伤亡、设备损坏,同时减少了滑坡对露天采坑排水、井下开采在露天采坑排渣作业的不利影响,对其他露天矿山边坡的安全管理具有重要的指导意义。

The multi-bench slope failure of Jinfeng open pit south wall which occurred on 24 th May, 2015 was successfully predicted through daily visual observation and dynamic, real-time, continuous and automatic slope monitoring,applying the theory and methodology for slope failure prediction both at home and abroad. The prediction included forecast of failure location, forecast of failure shape and scale and forecast of the time of the failure. No personnel injury and equipment damage is caused due to timely withdrawal before slope slide.Thus reducing the adverse effects on open pit drainage and UG waste dumping work in the abandoned open pit is instructive for the slope safety management at other open pit mines.
