摘　　要：边坡失稳破坏是露天矿山开采的重大风险,原位监测作为变形信息反馈和边坡破坏预警的手段,对边坡安全风险预报有重要意义。虽然近年来边坡监测技术取得了长足进步,但边坡监测设计依然面临一些瓶颈,如监测系统合理配套设置、预警阈值确定困难等。根据非煤矿山的有关规范,确定边坡监测内容;结合露天矿边坡多源多场安全监测主流的“空-天-地”一体化监测技术,优选安全经济的监测方法;由近年来一些露天开采滑坡的实际监测案例,用四级预警体系,给出了监测设计边坡预警阈值。研究从边坡监测的各个环节出发,形成了基于多源数据的露天开采边坡安全监测整套设计方法。Slope instability and failure are significant risks in open-pit mining.As a means of feedback on deformation information and early warning of slope failure,in-situ monitoring is of great significance for predicting slope safety risks.Although slope monitoring technology has made significant progress in recent years,slope monitoring design still faces some bottlenecks,such as reasonable matching of monitoring systems and difficulties in determining warning thresholds.Determine the content of slope monitoring according to relevant regulations for non-coal mines;Combining the mainstream“air sky ground”integrated monitoring technology of multi-source and multi-site safety monitoring for open-pit mine slopes,select safe and economical monitoring methods;Based on some actual monitoring cases of open-pit mining landslides in recent years,the early-warning threshold of slope monitoring design is given by using the four level early-warning system.The research starts from all aspects of slope monitoring and forms a complete set of design methods for open-pit mining slope safety monitoring based on multi-source data fusion.
