Aiming at the problem of low prediction accuracy of traditional methods, this paper proposes a research on hydrogeological disaster risk prediction of Dachang Gold Deposit in Qinghai Province. After selecting the five predictors -- geological structure characteristics, meteorological characteristics, groundwater system, rock development degree and stratigraphic characteristics, the prediction index system for hydrogeological disaster risks was established by the predictors; then the analytic hierarchy process was used to determine the weight of the predictor, and the fuzzy information comprehensive predictive function was used to perform fuzzy calculation and normalization on the predictors. Finally, the fuzzy method was used to solve the function and then obtain the result of hydrogeological disaster risk prediction, thereby realizing the hydrogeological disaster risk prediction of Dachang Gold Deposit. Relevant experiments have proved that this method has high prediction accuracy.
