基于微震和地音监测的冲击危险性综合评价技术研究
Study of comprehensive evaluation technology for rock burst hazard based on microseismic and underground sound monitoring
【摘要】 采用微震和地音监测系统对千秋煤矿煤岩震动信息进行了联合监测,研究确定了千秋煤矿评价冲击危险性的微震和地音指标。根据微震和地音系统不同的监测对象和监测区域,建立了千秋煤矿基于微震和地音监测的冲击危险性联合评价模型,提高了冲击地压的预测水平。
【Abstract】 Adopted mcroseismic and underground sound monitoring system to monitor information of coal-rock vibration for Qianqiu Coal Mine.On this basis,analyzed and determined the indexes of microseismic and underground sound to evalute rock burst hazard of Qianqiu Coal Mine.The comprehensive evaluation model of rock burst hazard was established which according to the different objects and monitoring area of mcroseismic and underground sound monitoring system.Through the comprehensive evaluation,the level of rock burst evaluation was improved.
