By using reverse tracer particle theory, the seepage coefficients and the specific yields of Tongling Xinqiao pyrite aquifers are obtained according to their hydro-geological and engineering geological conditions by pump pressure test. To identify the source of water inrush, a Modpath visualization model for water inrush is established. Water penetration rules are quantitatively researched by time step, and source direction, influencing range and degree of water inrush are analyzed. Results show that the fissure zone and the rift zone of the aquifer upon water inrush are important supply for the water inrush. The model has strong visual discrimination ability and can clearly discriminate mine water inrush.
