In order to effectively early warning of the susceptibility of the pressure appearance of the quarry, through the field investigation, 8 kinds of influencing factors, such as buried depth, compressive strength and roof management, are selected as the evaluation indexes, the weight of each evaluation index is given by using the coefficient of variation method, and the early warning model of the pressure display of the mining site is established based on the This model is applied to the oil depot and 5-1 working face of Cheng Chao Iron mine, and the susceptibility of oil depot and 5-1 face in the process of tidal iron mine is predicted by analyzing the size of the close value. The results show that the oil depot has the risk of low susceptibility, 5-1 working face has the danger of being prone to hair, and the early warning results of the model are consistent with the actual situation. It can be seen that this method is effective and feasible, and can provide useful guidance for the early warning of the pressure appearance of mine mining site.
