In order to find out the influence of water disaster in 2-3 coal seam roof mining in Gaotouyao Coal Mine, the “three-graph and double-prediction method” coupled with GIS and AHP was used to construct the water abundance evaluation model of 2-3 coal seam roof water-filled aquifer. Comprehensive comparison of FLAC3D numerical simulation, empirical formula calculation, analogy measurement and other methods, the traditional calculation formula of fractured water-conducting zone height was modified. On this basis, the classification and zoning map of water gushing (inrush) risk of 2-3 coal seam roof water-filled aquifer was obtained by compound superposition. Numerical simulation was used to predict the water inflow of Gaotouyao Coal Mine. The results show that the risk of water inrush in the central and southwest of Gaotouyao Coal Mine is higher, and the risk of water inrush in the northwest and east is lower. The normal water inflow of Gaotouyao Coal Mine is 465 m3/h, and the maximum water inflow is 558 m3/h. In view of the water disaster problems faced by the mine in the future, the feasible prevention and control measures have been put forward comprehensively.
