NUMERICAL STUDY ON THE MINING-INDUCED WATER OUTBURST IN DEEP TUNNEL WITH FAULTS

  • For mining-induced water outburst in deep tunnelof Hongtoushan Copper Mine, a hydraulic model for rock mass inCopper mine is proposed, based on the hydro-geological conditions in Hongtoushan Copper Mine. The Coupling Systemof Flow \& Solid in Rock Failure Process Analysis is applied to simulate andstudy the whole process of the initiation of fractures, extension andformation of water inrush pathway. With the analysis of damage distribution,stress and seepage field evolution, the process of the evolution fromsurrounding rock to inrush pathway is clearly revealed, and the water rushpathways are determined. The work can provide a scientific guide for the supportand watertight design of tunnel.
