Microseismic signal three-dimensional monitoring and early warning system for coal mine

The utility model discloses a micro-seismic signal three-dimensional monitoring and early warning system for a coal mine, which relates to the technical field of mine micro-seismic monitoring and comprises a data acquisition system arranged above a mine, an underground micro-seismic monitoring system and a ground micro-seismic monitoring system, the underground micro-seismic monitoring system and the ground micro-seismic monitoring system are in communication connection with the data acquisition system, and the data acquisition system is provided with a main clock source. The underground micro-seismic monitoring system is provided with a slave clock source, the ground micro-seismic monitoring system is provided with a GPS antenna, and the master clock source is in clock synchronization with the slave clock source and the GPS antenna. The combined three-dimensional micro-seismic monitoring with synchronous underground clock and underground clock is established, and the three-dimensional structure of the micro-
