Abstract: Based on the geological condition of Luohe Formation sandstone aquifer above the deep working face of 4# coal in Gaojiapu Mine, Binchang Mining area, the relationship between aquifer and dynamic disaster breeding is discussed. Firstly, the formation and its setting condition of the aquifer above 4# coal seam are introduced. Based on field water inflow monitoring data, we examined the relationship between the resistance of the support and the change of water inflow. The temporal and spatial correlation between micro seismicity and water movement is analyzed and identified, which will offer significant value for the early-warning of the dynamic hazards and water inrush. We expound the dynamic and static load of confined water movement on the working face after the increase of water inrush, and point out that it is important to pay more attention to the dynamic disaster risk of the working face after the water surge.
