融合空间聚类与工程约束的矿山微震自动分区预警方法研究OA

Aiming at the difficulties in automatic early warning of mine microseismic monitoring,this paper proposes an automatic zon-ing early warning method for mine microseismicity based on hierarchical clustering and engineering space constraints.Firstly,the appli-cation of the spatial hierarchical clustering algorithm in the spatial zoning of microseismic events is expounded.By comparing multiple clustering algorithms,the advantages of the group average clustering method are determined,and its calculation process is introduced in detail.Secondly,considering the special spatial separation of mine engineering,a mine space constraint correction method is proposed to optimize the zoning results.Finally,some microseismic data of Fankou lead-zinc mine are used for verification.Through clustering and correction,reasonable zoning of microseismic events is achieved,and judgments are made according to specific early warning indi-cators.The results show that this technology effectively improves the effectiveness and response speed of mine microseismic monitoring and early warning,and realizes the scientific management of ground pressure disasters.
