This paper contains an analysis on the main reasons for the changes of hydrogeological conditions and the short-term surge of underground water inflow caused by the combination of open-pit and underground mining in a copper mine in Jiangxi Province. On this basis, the water inflow and drainage capacity are re-verified and targeted water control measures are put forward, which can provide a good reference for water prevention and control works for open-pit and underground combined mines in rainy areas at home and abroad.
