Research of Security Assessment System of Coal Mine Based on AHP-FCE

Security assessment is an important content of security management system of ocal mine.Combined with base theories of analytic hierarchy process(AHP) and fuzzy comprehensive evaluation(FCE),the paper proposed a new security assessment system of coal mine based on AHP-FCE.The system establishes model of hierarchy structure aiming at security assessment factors of coal mine,adopts analytical hierarchy process to build comparison matrixes and takes eigenvectors of coupled comparison matrixes as weights of security assessment.It also adopts method of fuzzy comprehensive evaluation to do comprehensive evaluation to each evaluation factor,so as to make sure influence sequencing of evaluation factors.Results of actual examples showed that the security assessment system of coal mine based on AHP-FCE has simple operation and good generality,as well its calculation results are accurate and stable.
