摘　　要：针对目前单分站微震监测系统在监测区域上的局限性,开发了一种基于多分站的KJ699微震监测系统。该系统基于多分站时钟同步技术,引入全矿井监控概念,把监测区域从一个回采工作面扩展到整个矿井,同时,基于矿井监测尺度,引入了波速校准、最优通道选择技术对微震震源定位方法进行了优化。现场测试结果表明,该系统能实时监控更大范围的微震,提高了定位精度及自动化程度,为微震活动的动态分析、冲击地压等动力灾害的评价预警提供了更好的基础信息。For monitoring range limitation of current single-substation micro-seismic monitoring system,a KJ699 micro-seismic monitoring system based on multi-substation was developed.The system uses multi-substation clock synchronization technique,introduces concept of mine-wide and extends monitoring range from one coal face wide to mine-wide.Meanwhile,the system optimizes location method of micro-seismic focus by use of velocity calibration and optimal channel selection technology based on the mine-wide monitoring scale.The field test result shows that the system can monitor a wider range microseismic,and enhances location accuracy and automation capability,which can provide better basic information for seismic activity analysis,risk assessment and pre-warning of rock burst.
