Abstract Based on the geological condition of Yushupo Mine, hydrogeologic analogy and big well method were adopted to predict mine water inflow, the simulation result corresponded to the actual situation, the normal water inflow was 96 m3/d, the maximum water inflow 240 m3/d. Combined with the water analysis of the mine, parameters of goaf water and Ordovician limestone water inrush coefficient were calculated, the result showed that the water source came from goaf and deep Ordovician limestone water, the water predication and water discharge should be strengthened.
