Abstract The north mine of Dongpang Mine is a typical carboniferous Permian mine in North China. The thickness of the water separator between the coal seam and the Olympic ash aquifer was about 37 m, which was seriously threatened by the Olympic ash water. In view of the current situation, a high-precision microshock monitoring system was established in the north mine of Dongpang Mine, and the on-site monitoring data were obtained in real time. The spatial distribution of the monitoring data was analyzed and studied, combined with the underground production activities, and verified with the actual micro-shock events, so as to provide a basis for the safe production of the mine.
