Water prevention and control is an important part of maintaining safe production and sus⁃

tainable development of mines. An iron mine is a karst water mine.It is expected that the water inflow after

mining can reach 19 164.36 m3 /d，which brings potential safety hazards to mining operations. A karst water⁃

rich iron mine is expected to have a water inflow of 19 164.36 m3 /d after mining，which brings safety hazards

to mining operations. Based on the hydrogeological characteristics of the mine and the actual underground

mining conditions，the methods of advanced water exploration，curtain grouting near the ore body and anti⁃

seepage curtain to strengthen the water-proof pillar are adopted. Finally，a completely closed water-proof

body is formed in the upper middle ore body，and an incompletely closed anti-seepage and water-proof lay⁃

er is formed in the lower middle ore body. The proposed′ lugging and avoidance combination，prediction

first′ joint water prevention and control scheme can effectively ensure the safe mining of ore bodies，which

can be used as a reference for similar large water mines.
