Abstract: The paper analyzed the special water bearing porous formed under the mining interferences.The water bearing medium affected by the mining in the aba ndoned mine could be typified in to four type medium, such as the mine shaft and roadway pipeline collected water drainage medium, the high penetrated network crack s medium from the layer distributed mining and excavation caved rocks, inhomogeneous and irregular distributed turbulent crack medium and the breaking medium from the discrete distributed regional water control structure.With the description of the water dynamics features of different water bearing medium, the paper pointed out tha t the underground water flow in the mine roadway system would be a turbulent flow and other mediums would be vadose. The paper provided that when the underground water in the abandoned mine rose, water would flow along the mine road and penetrate to the surrounding rocks. Finally according to the water balance theory and the fi lling and discharging relationship, a calculation method of the different medium mutual changing water quantity was provided and the analysis on the coupling relations hip was conducted.
