GNSS监测技术在露天矿边坡监测预警中的应用

Application of GNSS monitoring technology in monitoring and warning of open-pit mine slopes

为探究智能监测云平台在露天矿边坡安全监测预警的运行可靠性,以内蒙古中部某露天矿为研究对象,运用GNSS自动变形监测技术,在排土场和采掘场边坡布设监测点和监测线进行研究分析。结果表明:在边坡受到春融和降雨影响时,位于采场与排土场边坡的监测点准确显示边坡持续变形;其次位于外排土场北侧6号监测点,竖向位移持续变形较大,验证了监测云平台在边坡变形监测预警的可行性。

In order to explore the operation reliability of intelligent monitoring cloud platform in open-pit mine slope safety monitoring and early warning,taking an open-pit mine in central Inner Mongolia as the research object,we use GNSS automatic deformation monitoring technology to study and analyze the monitoring lines and monitoring points in the slope of dump and excavation site.The results show that when the slope is affected by spring melting and rainfall,the slope monitoring points located in the stope and the dump accurately show the continuous deformation of the slope;secondly,located in the north side of the external dump No.6 monitoring point,the vertical displacement continues to deform larger,which verified the feasibility of monitoring cloud platform in slope deformation monitoring and early warning.
