In response to the complex mechanisms and multiple influecing factors of mine goaf water, in this study, the method of multi-source information fusion was proposed to evaluate the risk of goaf water damage in mine. The evaluation index system of mine goaf water damage was constructed according to the characteristics of mine goaf water damage in mine, and the main control factors were treated with grid and normalization. The analytic hierarchy process (AHP) was adopted to calculate the weight coefficients of main factors affecting the risk of mine goaf water damage. An evaluation model of mine goaf water based on the multi-source information fusion was established. The model was applied to the comprehensive evaluation of mine goaf water damage in Wuhushan Mine of Wuhai Energy Co., Ltd. The research results show that the method is reasonable and feasible.
