摘　　要：针对新疆某矿山井下结构围岩破碎明显、部分巷道出现片帮及冒顶等动力灾害的问题,基于微震监测技术,建立了一套实时、在线的地压监测系统,对围岩破坏位置进行定位,进而对围岩应力集中程度进行评估。对所监测到的干扰信号进行剔除,分析了开采区域微震事件时空分布特征,得出微震事件集聚区与开采爆破区域相一致,同时现场岩体破碎位置与微震事件集聚区域相吻合。基于微震事件,分析围岩应力变形特征,得出风险较大区域,该研究保障了矿山生产安全,为矿山安全提升提供技术支撑。A real-time and online ground pressure monitoring system has been established based on microseismic monitoring technology to address the problem of significant rock fragmentation and dynamic disasters such as rock fragmentation and roof fall in some areas of a certain mine underground structure in Xinjiang.This system can evaluate the stress state of the surrounding rock.The monitored interference signals are removed,and the spatiotemporal distribution characteristics of microseismic events in the mining area are analysed.It is found that the concentration area of microseismic events is consistent with the mining blasting area,and consistent with the relatively fractured rock mass on site.Based on microseismic events,the stress and deformation characteristics of surrounding rock are analysed to identify high-risk areas.This study ensures the safety of mining production and provides technical support for improving mine safety.
