构造活化的微震监测与数值模拟耦合研究

 Microseismic monitoring technology is applied to the catastrophe process monitoring of geological anomalous bodies，such as faults，karst collapse columns and high angle fractured zone long wall face. It provides dynamic information including propagation，growth and failure of the channel for warning the underground water inrush hazard of dangerous working face. Coupling analysis of displacement field and stress field of surrounding rock at the working face by numerical simulation method and the activation information of geological anomalous bodies such as faults，karst collapse columns and high angle fractured zone obtained by microseismic monitoring technology is conducted to reveal the mechanism of tectonic activation and mutation induced by mining. According to the coupling analysis results，combined with the distribution of faults，karst collapse columns and high angle fractured zone at tested working face，some targeted water proof and control projects are implemented. The analysis results prove that the coupling analysis method of microseismic monitoring and numerical simulation can be used to study the tectonic activation and can provide guidance for water proof and control of mining project.
