基于GNSS的尾矿库在线监测系统研究与应用

Research and Application of Online Monitoring System for Tailings Pond Based on GNSS

针对尾矿库的筑坝监测以及对尾矿库坝体的维护与管理技术水平不高这一问题,本文采用GNSS方法对坝体表面位移进行变形监测,并差分、解算出各监测点的空间坐标,分析变化量,建立自动监测系统,实时了解尾矿库坝的安全状态并做出预测、预警,有效防范和化解尾矿库安全风险,减少尾矿事故带来的不必要损失。根据实际项目建设的基于GNSS的尾矿库在线监测系统,对矿山环境调查、尾矿库变形监测分析、尾矿库环境风险评估、尾矿库溃坝灾害推演、尾矿库安全管理等研究领域具有一定的借鉴作用。

Aiming at the low technical level of dam construction monitoring and maintenance and management of tailings pond dams,this paper adopts GNSS method to monitor the deformation of dam surface displacement,and calculates the spatial coordinates of each monitoring point by difference,analyzes the changes,establishes an automatic monitoring system,understands the safety status of tailings pond dam in real time,makes prediction and early warning,and effectively prevents and resolves the safety risks of tailings pond,reduces unnecessary losses caused by tailings accidents.The online monitoring system of tailings pond based on GNSS constructed according to the actual project has a certain reference function for the research fields such as mine environment investigation,deformation monitoring and analysis of tailings pond,environmental risk assessment of tailings pond,deduction of dam break disaster of tailings pond,and safety management of tailings pond.
