To solve the problem of complex and variable moderately inclined thin ore body mining in a gold mine,based on the initial selection of mining methods,the method of analytic hierarchy process and fuzzy mathematics comprehensive evaluation was comprehensively applied,and 8 indicators such as safety,ventilation conditions,mechanization degree,mining cut ratio,mining production capacity,ore dilution rate,mining loss rate,and process complexity were qualitatively and quantitatively weighted to determine the optimal scheme.The finally optimized mining plan was verified by on-site industrial tests,and the technical and economic indicators of the mining field were greatly improved.The on-site test results further verified the engineering feasibility and effectiveness of the analytic hierarchy process and fuzzy mathematics comprehensive evaluation in mining method optimization.
