快速静态技术在新立尾矿库监测中的优化研究

Research on Optimization of rapid static technology in monitoring of Xinli tailings pond

三山岛金矿新立尾矿库原采用拓普康全站仪进行监测,但效率低。针对坝体沉降位移监测、地形地貌增测及矿区厂房建筑变形观测等测设的需求,研究采用优化后的快速静态测量技术进行监测。介绍了监测点的布设、监测结果精度评定和数据处理。实践结果表明:优化后的快速静态测量技术监测结果精度满足要求,能够准确反映尾矿库现状及移动趋势,其中4个监测点变形超限,进而对其边坡及排水沟进行加固处理,为矿区安全高效回采提供了有利保障。

The Xinli tailing pond in Sanshandao gold mine used to be monitored by TOPCON total station,but its efficiency was low.According to the requirements of dam settlement and displacement monitoring,topographic and geomorphic additional measurement and deformation observation of workshop buildings in mining area,the optimized fast static measurement technology is studied.The layout of monitoring points,accuracy evaluation of monitoring results and data processing are introduced.The practical results show that the accuracy of the monitoring results of the optimized rapid static measurement technology meets the requirements,and it can accurately reflect the current situation and moving trend of the tailings pond,among which the deformation of four monitoring points exceeds the limit,and then the slope and drainage ditch are reinforced,which provides a favorable guarantee for safe and efficient mining in the mining area.
