Abstract：A seepage model test system for mining tunnel during construction and operation period has been used to predict the water inflow of a tunnel without considering the influence of excavation disturbance. The test conditions include the different permeability coefficient of grouting circle and initial lining. The numerical analysis was carried out with the Visual-modflow. The results from experiment and numerical analysis are basically consistent. The average value of water inflow is nonlinearly decreased with the decreasing of the permeability coefficient of the grouting circle and the initial lining，and the variance of single test value in each condition is also gradually reduced. The effect of reducing the permeability coefficient of grouting circle on the water inflow is more obvious. When the permeability coefficient of grouting circle was changed，the continuous collection of water inflow in each condition decreased first and then increased gradually to a stable value. And when the permeability coefficient of the initial lining was changed，the water inflow showed the trend of the gradually decreasing until it reached a balance. Non-disturbed excavation makes the groundwater to flow towards the tunnel which leads to the notable increase of hydraulic gradient around tunnel. The distribution of isopiestic line is dense and presents a concave shape in the direction of tunnel excavation. The well-functioning of the waterproof system(primary lining and grouting circle) played a significant role in maintaining the stability of groundwater. It effectively reduced the local hydraulic connection，reduced the influence of the seepage. The lowering of groundwater table was also significantly reduced.
