Abstract: In combination with the current situation of water gushing in the stope and mine drainage system of Shilu Iron Mine in Hainan Province，and in view of the characteristics of heavy rainfall and fast water flow in the tunnel during the typhoon storm season，a mine drainage scheme is proposed，which is mainly composed of drainage，supplemented by blocking，and combined with dredging. It is managed in five links of "interception，drainage，blocking，drainage，and protection". Four flood control ditches are set in the open air to intercept rainwater，and the rainwater infiltration speed is controlled through waste rock cushion，multi-stage sedimentation facilities，water retaining dams and drain holes are set on the wa⁃ ter flow lines of the underground stope，which not only unblocks the mine water inflow lines，reduces the water accumulation in the stope，but also effectively prevents the mud and sand from entering the sedimen⁃ tation tank and water bin，creating favorable conditions for the safe operation of drainage equipment.

Key words: water inflow in stope, intercepting ditch, retaining dam, sedimentation tank
