现场监测与数值模拟相结合的矿山灾害预测预警方法

在矿产资源需求量大,而国内矿产资源储量逐渐减少、易采矿产逐步枯竭的情况下,矿山逐渐转向对深部资源的开采,随着采深的增加,开采诱发的岩爆、冒顶片帮等多种灾害日益凸显,矿山灾害预测预警势在必行。总结了当前基于现场监测和数值模拟方法分别进行矿山灾害预测预警的优缺点,提出了一种现场监测与数值模拟相结合的灾害预测预警方法,以实现矿山灾害的趋势预测与实时预警。分析了该方法的可行性与优势,并以矿山常见的露天边坡稳定性分析为例,阐述了该预测预警方法的实际应用,供相关研究参考。

Prediction and Early Warning of Mining-induced Disasters Based on Combined In-situ Monitoring and Numerical Simulation

In the case of large demand for mineral resources,gradual reduction of domestic mineral resources reservesand gradual depletion of easy-to-exploit minerals,mines gradually turn to the exploitation of deep resources.With the increaseof mining depth,rock burst,roof fall and other mining-induced disasters become increasingly prominent,and mine disasterprediction and early warning is imperative.This paper summarizes the advantages and disadvantages of mine disaster predic-tion and early warning based on in-situ monitoring and numerical simulation respectively,and puts forward a method to predictthe tendency and to early-warn the mine disasters.The feasibility and advantages of this method are analyzed,and the practicalapplication of this method is expounded by taking the stability analysis of open-pit slope as an example so as to provide somereliable reference for the related studies.
