摘　　要：针对隐蔽性导水构造的精细探查技术与装备不足,利用井下高精度微地震监测系统,可以实现对开采过程中的岩层破裂规律、构造活化过程进行三维连续动态监测,结合采场覆岩空间结构理论,进行底板突水的监测和预警。工程实践证明:微震监测能够准确判断出工作面岩层破裂范围,岩层运动异常区域,建立基于定位结果和岩体破裂场的定量描述模型,该技术能够准确实现突水监测的超前预警预报。Aiming at the deficiency of fine exploration technology and equipment of hidden water conducted structure, it used under- ground high - precision microseismic monitoring system to ca,xy out 3D continuous dynamic monitoring for rock fracture law and tectonic activation in the mining process. Combined with the spatial structure theo^T of stope overlying strata, it condncted water inrush monito- ring and early warning. The engineering practice proved that microseismic monitoring could accurately judge the rock fracture range of working face, anomalous areas of rock movement, it established the quantitative description model based on positioning results and rock fracture field, this technology could accurately realize the advance warning and forecast for water inrush monitoring.
