Abstract：The analytical hierarchy process(AHP)and fuzzy mathematics were used to form a new assessment method of stope structural parameters.Dynamic,static,fixed and non-fixed factors,both quantitative and qualitative in nature,related to working on the stope were considered.Economic,safety and technical factors were included.AHP was used to weight the factor vectors and fuzzy mathematics was used to find the adapted membership degree.Given the weighted vectors and the membership matrix a fuzzy judge model was used to optimize the stope's parameters.Nine schemes,fitting an orthogonal model,were tested in the Kangjiawan lcad-zinc mine.Finite element simulations were used to find the influence of the factors and five of the nine schemes were assessed by the fuzzy synthetic judge model.The degree of"goodness"of the schemes was 60.5%,65,8%,78.5%,65.9%and 73.1%for the second,third,fifth,sixth and eighth ones,respectively.Hence the fifth scheme is the most optimum.
