Abstract：According to the situation of 31102 working face in Nariin Gol No.2 Coal Mine, the dangerous area of a strong mine pressure accident is divided, and dynamic real-time monitoring of strong mine pressure is realized in the working face. The theoretical model is used to analyze the distribution law of advance abutment pressure in the working face. Based on the microseismic monitoring system, the temporal and spatial evolution of the overlying strata is analyzed, influence range of the advance abutment pressure on the working face and development of the fracture above the stope are determined. Statistical analysis of the data of the microseismic monitoring system is conducted to explore the relationship between recovery speed and microseismic events, and the reasonable advancing speed in the strong mine pressure danger area is proposed to reduce the risk of strong mine pressure behaviors and disasters.
