摘要
为了解决露天矿山边坡崩塌灾害预警这一难题,采用InSAR监测技术对露天矿山边坡进行了长时序连续监测,获取海量边坡形变监测数据,探讨了边坡体整体形变场及异常点形变数据特征,确定了崩塌灾害的潜在区域及位置.现场勘察结果表明:崩塌灾害潜在区域现场与研判预警结论相契合;基于InSAR监测技术,并结合边坡体特征进行边坡崩塌研判预警是可行的、预警结果是可靠的.
Abstract
In order to solve the problem of early warning of slope collapse disaster in open-pit mines,the article adopts InSAR monitoring technology to continuously monitor the slope of open-pit mines for a long time,and obtains massive slope deformation monitoring data,discusses the characteristics of the overall deformation field and abnormal point deformation data of the slope,and determines the potential area and location of the collapse disaster.Field investigation shows that the potential area of the collapse disaster was consistent with the conclusion of the research and early warning;it is feasible and reliable to combine the characteristics of the slope body to carry out the early warning of slope collapse based on InSAR monitoring technology.
