To accurately identify the location of the water inrush sources, correlation analysis and factor analysis were used to discuss the similarity of hydrochemical control mechanism of different aquifers and inrush water. On this basis, Fisher and BP neural network are used to judge the probability of inrush water. Finally, it is verified by hydrological observation holes. According to the water sources mixing model, the water inrush sources of 11601 working face were mainly No. 13 stratum Carboniferous limestone water with a s
