Abstract

For the microseismic events induced by water inrush in underground coal mine, this paper carried out the numerical calculation and simulation study of water-induced microseismic signals, and on this basis carried out the development of a monitoring system suitable for underground coal mine. In the research process, the numerical calculation of the characteristic parameters such as energy, amplitude and frequency of the vibration signal generated by the induced water disaster was realized. Combined with the internal structure of the moving coil detector, the electrical signal response calculation of the vibration signal was completed, and the electrical characteristic waveforms of different vibration signals were obtained theoretically. Based on the theoretical research results, the whole microseismic monitoring system is designed and developed. In this paper, the self-developed monitoring system is used to realize the effective capture of underground microseismic signals. The detection results show that the system can monitor the vibration signals generated by the disaster inducing water in real time, and provide technical support for the mine water disaster warning.
