The rock mass cracks caused by the surge of water pressure may become an important part of the water inrush channel. A large number of weak vibration signals will be induced during the hydraulic fracturing process. The source signal can be obtained by monitoring technology such as microseismic (MS) or acoustic emission. In the paper, the disaster-causing mechanism of water inrush disaster in tunnels is analyzed. The relationship between water inrush disaster and microseism is established. The main MS event is fracture development in the rock mass progressive failure water inrush. The main MS event is the impact activity of fillings and channel rock wall driven by water flow in the filling structure instability water inrush. The hydraulic fracturing test of rock-like materials is carried out. The effectiveness of acoustic emission (AE) monitoring technology is verified by comparing the fracture shape and AE positioning results. This study provides a theoretical basis for monitoring and early warning of water inrush disaster. At the same time, this research idea can provide reference for the study of engineering geological disasters such as large deformation and rockburst, and provide strong support for the safety construction of major infrastructure projects.
