A certain deposit encountered a certain degree of water inflow during the mining process. In order to solve the water inflow problem and provide a basis for water prevention and control plan, the deposit was taken as the research object, the hydrogeological conditions of the deposit were generalized by analyzing the hydrogeological conditions, types and characteristics of aquifers, groundwater recharge and discharge conditions, geological structural characteristics, hydrogeological parameters, hydrogeological test data, and mining design data. The hydrogeological units of the study area were delineated, and a three-dimensional groundwater flow numerical model was established using GMS software, the predicted water inflow of the mining pit in the middle section below -200 m was obtained.
