Abstract: For mining-induced water outburst in deep tunnel of Hongtoushan Copper Mine, a hydraulic model for rock mass in Copper mine is proposed, based on the hydro-geological conditions in Hongtoushan Copper Mine. The Coupling System of Flow {\&} Solid in Rock Failure Process Analysis is applied to simulate and study the whole process of the initiation of fractures, extension and formation of water inrush pathway. With the analysis of damage distribution, stress and seepage field evolution, the process of the evolution from surrounding rock to inrush pathway is clearly revealed, and the water rush pathways are determined. The work can provide a scientific guide for the support and watertight design of tunnel.
