| 摘 要： | 微震监测获取的数据中通常混有大量的非岩石破裂信号,该类信号目前主要通过人工经验进行识别与滤除,这消耗了大量的宝贵时间,严重影响灾害的防治和救援效率。对大量微震信号进行分析,发现STA/LTA算法在信号实时触发后能大致表征波形振幅和频率的变化,岩石破裂信号和非岩石破裂信号在延迟位置处R值具有差异性。基于此,提出了岩石破裂微震信号实时识别算法。新算法应用到白鹤滩水电站地下厂房、红透山和阿舍勒铜矿深部采场3个工程,岩石破裂事件识别的准确率分别是85.98%、92.45%和91.06%,非岩石破裂事件滤除的准确率分别是72.06%、83.11%和49.87%。该算法使基于岩石破裂微震信息的岩石工程灾害自动分析与预警成为可能,具有重要意义。
