Abstract: The previous analysis methods for hidden disaster-causing factors in coal mines are not conducive to an overall understanding of the risks in the mine. This paper takes the Zhunnan Mining Area of Changji Prefecture as the research object and uses the AHP to establish a risk assessment index system based on three factors: geological structural factors, natural geological factors, and exploration（mining） engineering factors. Based on the three factors, select 12 influencing factors such as fault, gas, roof, burning area, underground water body, goaf, and bad borehole closure to construct a risk assessment index system, construct a corresponding judgment matrix, and calculate index weights at each level. Based on the fuzzy comprehensive evaluation method, considering the degree of impact of hidden disaster-causing factors in mining areas on coal mine safety, the comment set is divided into five levels: higher risk, high risk, medium risk, low risk, and lower risk, and the fuzzy comprehensive evaluation method is determined. The evaluation matrix is evaluated by taking the Kuangou Coal Mine in Zhunnan Mining Area as an example. The research results show that in the evaluation index system, natural geological factors and exploration（mining） engineering factors have higher weights in the first-level indicators, and underground water body, gas, abandoned old kilns（shafts） have higher weights in the second-level indicators. The risk value of Kuangou Coal Mine in Zhunnan Mining Area is between 45 and 50 points, and the comprehensive risk level is medium risk. The evaluation results show that the method is applicable and reliable in the evaluation of hidden disaster-causing factors in coal mines in the Zhunnan Mining Area of Changji Prefecture.
