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。
In view of the lack of sophisticated exploration technology and equipment of concealed water conduction structure, the use of underground high-precision micro-seismic monitoring system can realize the rock burst law during the mining process and the three-dimensional continuous dynamic monitoring of tectonic activation process. Combining with the spatial structure of overlying strata Theory, to carry out floor water inrush monitoring and early warning. The engineering practice proves that microseismic monitoring can accurately determine the rock fracture range and rock movement anomaly area and establish a quantitative description model based on the location results and the rock mass rupture field. This technique can accurately predict the early warning of water inrush monitoring.
