尾矿库在线监测系统中位移数据分析方法探讨

尾矿库的安全稳定在矿山安全生产和环境保护中具有十分重要的意义,国家已明确要求三等及三等以上尾矿库应安装在线监测系统。本文在总结我国尾矿库在线监测系统结构和建设情况基础上,分析了当前已建成系统中坝面位移或坝内位移处理方法的现状和存在的不足,并提出科学合理地分析位移数据是关系到尾矿库在线监测系统有效性和适用性的关键技术之一。在总结归纳尾矿库安全领域坝体变形和稳定安全评价方法的基础上,提出了尾矿库在线监测系统中坝面位移和坝内位移定量分析处理的新思路,指出尾矿坝变形过程的数值仿真是校核在线监测系统所得位移数据,进而有效地分析和预测尾矿坝变形趋势的重要手段之一。

Study on displacement analysis methods of tailing ponds on-line monitoring system

The safety and stability of the tailing ponds plays an important role in the mining production and environmental protection.It is specifically requested that tailing ponds of grade three and above should install an on-line monitoring system.Based on the summarization of on-line monitoring system construction and building in China,this paper analyzed the current state and existing drawbacks of the disposal method of displacement on and inside dam body within the established on-line monitoring system and put forward that scientific and reasonable analysis of displacement data is one of key technique related to the effectiveness and applicability of tailing pond on-line monitoring systems.After analyzing the dam deformation and stability assessment methods,this paper also put forward a new idea for the quantitative analysis and handling of displacement on and inside dam body within a tailing pond on-line monitoring system.This paper also proposed that the numerical simulation of dam deformation is one of the important rules which could calculate on-line dam deformation,analyze and forecoast the developing value of dam deformation.
