Mine water disasters are a significant factor that constrains underground production activities. To effectively conduct protection work against mine water inrush, it is important to predict and analyze the risk degree of water inrush occurring in different middle sections. This study undertakes an in-depth analysis of the water inrush risk situation in the 2960-2660 m middle section of the Zaozigou Gold Mine. By establishing a fuzzy analytic hierarchy process (FAHP)–TOPSIS (FAHP–TOPSIS) coupling model, the concept of interval mathematics is incorporated into the TOPSIS method, and the risk grade is calculated using the coupling model. A finite difference model equation is established by utilizing Darcy’s law to visualize the water inrush risk situation in each middle section of the mine. The results indicate the following: (1) Among the 12 crucial factors affecting underground water inrush events identified and proposed in this paper, water richness has the most significant influence. (2) The degree of risk of water inrush in the 2760 m middle section under the mine is relatively high, the degree of risk in the 2710 m middle section is relatively low, and the degree of risk in the other middle sections is moderate. (3) The water inrush risk in each middle section of the Zaozigou Gold Mine exhibits no gradual increase or decrease trend but is closely related to specific underground geological conditions.
