Abstract: In the process of working face mining, mine pressure behavior plays an inducing role in some disasters, so it is necessary to warn the mine pressure. Based on the microseismic monitoring and on-site mine pressure monitoring during the mining process of No.N1100 Face in Yuwu Coal Mine, this paper analyzed the microseismic early warning indexes of mine pressure appearance. The results showed that the mine pressure appeared when the daily microseismic frequency was 40 times, the daily cumulative microseismic total energy was 5 × 104 J, and the maximum energy of a single microseismic event was 1 × 104 J, which provided a certain reference for the use of microseismic monitoring of mine pressure.
