Abstract:采用加拿大ESG
微震监测系统对锦州某大型地下水封石油洞库局部开挖过程进行实时监测和分析,圈定监测范围内围岩潜在危险区域,再现开挖过程中洞库失稳区域的岩体微破裂萌
生、发展和集聚。结果表明:(1)采用人工定点敲击试验对监测系统定位性能进行测试,确定研究区域岩体整体等效P 波波速为5 200
m/s,传感器阵列范围内的震源定位误差小于8
m;(2)监测区域岩体微破裂呈2个条带状聚集,一条位于水幕巷道6东侧,水幕巷道1和2范围,与水平面呈缓倾角。另一条位于储油洞室1北与1南范围2+
40~2+60里程区域内,与该区域辉绿岩脉分布范围一致,说明微震监测系统可以查明判别岩脉等软弱结构面情况。这是由于大断面的储油洞室的强开挖卸荷,
高能量的释放导致岩脉的过度损伤,从而诱发大量的微破裂。研究结果证明微震监测技术在地下水封石油洞库这种特殊岩体结构中应用的可行性,为后期大规模微震
监测系统的构建与实施提供参考依据。
