Abstract: According to the dangerous area of water inrush in 1612A working face of Zhangji Coal Mine and the characteristics of mining construction, the methods is proposed that the bolt is used as a signal medium for conducting rock mass fracture, and the micro-seismic monitoring sensors are reasonably installed in gas mine by means of bolt welding and bolting with anchoring agent. Based on the method, the real-time monitoring for dangerous area of water inrush is realized. The method is verified by the real-time waveform data and the micro-seismic event location. The results show that the driving speed of the working face is the same as the monitored micro-seismic event location of the roof and floor in 1612A working face. The abnormal points of the micro-seismic location in the bottom drainage roadway are basically consistent with the position of the pumps in the field.
