,Numerical Simulation Study on Mine Water–Sand Inrush Under Fluid–Solid Coupling,by the excavation activities, the roof rock is ruptured. Once the overlying aquifer is connected, the groundwater infiltrates the cracks, and the rock strength, shear strength, cohesion, and internal friction are affected by the hydraulic pressure of the groundwater.

Water Inrush Mode and Prevention Technology Under Bedrock Fissure Aquifers,Groundwater mainly occurs in rock voids, and the development of karst and fissures in rock mass is often heterogeneous and discontinuous, and their water conductivity and water storage capacity are also very different, which also makes the distribution of aquifer water abundance with great heterogeneity.
