Abstract: This paper introduces Fuzzy Analytic Hierarchy Process (FAHP), in light of the metal underground stope security's risk analysis in each master control factor weighted distribution question. The FAHP overcame the traditional hierarchical method matrix structure subjectivity and consistency is not easy inspection defect. The paper introduced the FAHP basic principle and mathematical model's establishment, finally this method is applied to the metal underground stope's security risk analysis of various controlling factors in the quantitative calculation of the weight distribution.
