摘要
某金矿在深部开采过程中,频繁出现顶板冒落、矿柱片帮、岩爆等地压灾害,并存在民采活动扰乱矿山正常生产秩序。通过台网分析及波速校正,设计并建设了满足矿山安全监测的微震监测系统。运用微震监测数据高精度定位震源,分析了定位事件的时空演化规律,评估了监测范围内岩体稳定性,同时定位得到了民采活动区域,为矿山安全生产提供了保障。
In the deep mining process of a gold mine,roof caving,pillar block,rock burst and other ground pressure disasters occurred frequently.And the existences of the private mining disturb the normal production order of the mine.Through the analysis of the network and the correction of the wave velocity,a microseismic monitoring system for mine safety monitoring was designed and constructed.By using microseismic monitoring data to locate the source with high precision,the space-time evolution rule of positioning events is analyzed,the stability of rock mass within the monitoring range is evaluated,and the location of the private mining area is located.It provides a guarantee for the safety of mine production.
