深部位移监测在贺斯格乌拉露天煤矿的应用

Application of deep displacement monitoring in Hesigewula Open-pit Coal Mine

深部位移监测是通过实时深入监测岩土层内部变形,测量岩土层不同深度地层的水平位移量、水平位移方向和变形速率,进而识别和判断岩土层各个时段的发展趋势;对深部多物理量测量仪的工作原理和功能结构特点进行了介绍;在内蒙古自治区锡林郭勒盟的贺斯格乌拉露天煤矿布置6个深部位移监测钻孔,共有199个位移监测点;从2019年12月至2020年10月共采集到1180750条监测深部位移监测数据记录。监测结果表明:在露天矿边坡深部监测中,使用阵列式位移传感系统进行滑坡体深部进行监测,不仅能够实时有效地捕捉深部相对位移的大致位置及错动距离,还能监测到滑坡体深部位移的变形情况。

Deep displacement monitoring is to measure the horizontal displacement,horizontal displacement direction and deformation rate of the rock and soil layer at different depths through real-time and in-depth monitoring of the internal deformation of the rock and soil layer,and then identify and judge the development trend of the rock and soil layer in various periods.The article introduces working principle and functional structure characteristics of the deep multi-physical quantity measuring instrument,deploys six deep displacement monitoring boreholes in the Hesigewula Open-pit Coal Mine of XilinGol League,Inner Mongolia Autonomous Region,with a total of 199 displacement monitoring points.From December 2019 to October 2020,we collect a total of 1,180,750 monitoring data records of deep displacement monitoring.The monitoring results show that in the deep monitoring of the open-pit mine slope,the array displacement sensing system is used to monitor the deep part of the landslide body,which can not only effectively capture the approximate position and displacement distance of the deep relative displacement in real time,but also monitor the deformation of landslide body deep displacement.
