Abstract: In order to study the main influencing factors of water inrush from the working face of Jiaozuo mining area and how to take corresponding prevention measures,select geological structure λ1,coal seam thickness λ2,coal seam dip angle λ3,working surface width λ4, mining depth λ5, aquifer head pressure λ6, septumThe average intensity of water layer λ7 and the average thickness of water-repellent layer λ8 were used as research variables to establish a factor analysis model for water inrush from the working face of Jiaozuo mining area. The results show that the eight variables of water inrush from the floor of Jiaozuo mining area can be summarized as mining occurrence factor, mining design factor and technical variable factor. It is concluded that the model weighted comprehensive score ≥0.95 is very dangerous and needs to be taken. The discriminant standard of the corresponding technical measures; the factor analysis model was successfully applied and verified in the 11011 working face of Zhaogu No. 2 Mine. The research results of the thesis provide a certain reference significance for whether the floor of the mining face under the mining area and similar geological conditions needs grouting reinforcement or other prevention measures.
