Resolving the potential groundwater yield zonation of sandstone aquifers is an important task for prevention of flood hazards from coal roof in coal mines. Based on the accessible geological exploration data, we presents a method of predicting the potential groundwater yield zone in sandstone aquifers based on entropy weight method (EWM) and the technique for order performance by similarity to ideal solution (TOPSIS). The relationships between the factors and groundwater yield in sandstone aquifers were discussed and determined by EWM. And finally, a potential groundwater yield contour map was constructed by PGYI values using TOPSIS method. And the field data were used to test the accuracy of the prediction model.
