Abstract: In view of mine water inrush simulation,the modeling research was divided into two parts：the static modeling of laneways and the dynamic simulation of water inrush spreading process.Based on the point-line concept,the laneways were modeled with equivalent length to unify the parameters of time and length.Combining the characteristics of mine water inrush,graph theory and intelligent search algorithm,the downward and upward water spreading processes during the water inrush development were researched.With the fixed time-step method,the simulation clock system was established to realize the forecast and reappearance of laneways and water,before and after the water inrush.The simulation modeling algorithm of mine water inrush was completed and the system prototype was implemented.A typical metal mine in China was exemplified to verify the feasibility and effectiveness of the simulation system.The model and the system prototype provided the technical means for prevention,rescue and research work of mine water inrush.
