北斗卫星系统在排土场位移监测中的应用

Application of Beidou Satellite System in Waste Dump Displacement Monitoring

根据露天矿山排土场边坡形变监测需要,在排土场地质条件及周边环境勘察结果的基础上,应用北斗高精度定位技术,分别在排土场1590、1586、1580平台边坡布设5个北斗位移监测点,实现对排土场边坡形变的实时监测。对连续10个月的形变监测数据的统计分析表明,排土场施工作业导致各监测点边坡垂直方向形变,1590平台边坡垂直形变显著(垂直形变月累积量平均约为6.0 mm),其他平台边坡垂直形变月累积量平均值小于3.0 mm,各监测点均未出现形变加速或阶跃变化,排土场边坡尚处于平稳期。北斗卫星系统在排土场位移监测中的应用,为边坡形变趋势预测和安全预警提供了自动化的监测手段和原始监测数据,保障了露天矿山排土场堆放作业的安全。

Based on the geological conditions and surrounding environmental survey results of the open-pit mine waste dump slope deformation monitoring,using the Beidou high-precision positioning technology,five Beidou displacement monitoring points were set up on the 1590,1586 and 1580 platform slopes of the waste dump,and the real-time monitoring of the slope deformation of the waste dump was achieved.The statistical analysis of deformation monitoring data for 10 consecutive months shows that the construction of the waste dump has led to the vertical deformation of the slope at each monitoring point.The vertical deformation of the 1590 platform slope is significant,with the average monthly cumulant of deformation about 6.0 mm,and the average monthly cumulant of the vertical deformation of other platform slopes is less than 3.0 mm.No acceleration or step change of deformation has occurred at each monitoring point,and the waste dump slope is still in a stable period.The application of Beidou satellite system in displacement monitoring of waste dump provides automated monitoring methods and raw monitoring data for slope deformation trend prediction and safety warning,ensuring the safety of open-pit mine waste dump stacking operations.
