The invention discloses a coal mine safety management risk method, which belongs to the technical field of risk evaluation. The method comprises steps: data collection is carried out; data statisticsis carried out; data processing is carried out, the data are subjected to reliability and validity analysis, and final variables are obtained; according to the relationship between the final variables, a hypothetical variable is put forward; a structural equation model is built for the final variables and the hypothetical variable which is put forward; overall fitting and internal structure fitting on the model are carried out, and according to two standard fitting degree of the model, model evolution is carried out; fitting modification test is carried out on the model, a model fitting goodness index after modification is acquired, and model fitting goodness indexes before and after modification are compared; and a final conclusion is obtained. According to the technical scheme disclosedin the invention, various
