蚕庄金矿岩爆自动化预警系统研究

Research on Automated Early Warning System for Rockburst in Canzhuang Gold Mine

为了研究对蚕庄金矿潜在岩爆灾害进行预警,本文分别构建了岩爆及工程地质灾害微震监测案例库、蚕庄金矿岩爆风险预警指标以及岩爆监测预警云平台,研究结果表明:①能量指数及视应力显著下降,视体积、频次及能量显著上升是最为常见的岩爆前兆现象;②结合岩爆微震监测案例库及空间聚类算法,岩爆风险预警指标为微震事件聚集区域的能量指数及视应力显著下降40%以上,视体积、频次及能量显著上升40%以上;③蚕庄金矿岩爆监测预警云平台可实现矿山微震监测数据远程传输、存储、传输与可视化查询以及岩爆风险预测预警等功能。研究成果可为类似矿山的岩爆预警提供参考依据。

In order to study the potential rockburst disaster early warning of Canzhuang gold mine,this paper constructed a rockburst and engineering geological hazards microseismic monitoring case library,Jiamzhuang gold mine rockburst risk warning indicators and rockburst monitoring and early warning cloud platform.The results of the study show that:①the energy index and apparent stress decreased significantly;the apparent volume,frequency and energy increased significantly is the most common precursor phenomenon to rockbursts;②combined with the rock burst microseismic monitoring case library and spatial clustering algorithm,rock burst risk warning indicators for microseismic events gathered in the area of the energy index and apparent stress decreased significantly by more than 40%;the apparent volume,frequency and energy increased significantly by more than 40%.③Canzhuang gold mine rock burst monitoring and early warning cloud platform can realize mine microseismic monitoring data remote transmission,storage,transmission and visualization query and rock burst risk prediction and early warning functions.The research results can provide reference basis for rock burst early warning of similar mines.
