中文摘要:三山岛金矿直属矿区进入深部开采时出现岩爆现象,同时生产区域存在岩爆诱发的矿柱失稳的危险,为保证深部开采生产安全,需要进行岩爆监测和预警。针对矿区特有的地质、生产条件,布置适合监测矿山深部安全开采的微震监测系统,得到大量监测数据。基于监测结果的系统分析,研究了深部岩爆预警技术思路和岩爆危险区域的预报方法。结果分析表明,通过运用微震监测系统,能够达到全面监控目标区域的岩石稳定状况和动态,实现深部开采的安全监测和岩爆预警。

Analysis on microseism monitoring and rock bursts proneness in Sanshandao gold mine
Abstract:The phenomenon of rock burst appears while deep mining in Sanshandao Gold Mine.The dangers of instability are induced by rock burst in production area,Which requires monitoring and early warning.Based on the test results of microseism monitoring system for monitoring the safety of deep mining,the technical approaches of prewarning for deep rock burst at deep zone are studied based on the seismic monitoring,including the forecast of dangerous rock burst zone,The result showed that,monitoring and early warning of deep mining are achieved through the comprehensive monitoring of the rock steady state and dynamics of the target area.
