Construction And Application On Comprehensive Evaluation Index System Of Intrinsic Safety For Mine

Intrinsic safety comprehensive evaluation for coal mine is to achieve intrinsic safety. Andthe complication of coal mine production system decides it will be a complicated project. Soit is critically important to conduct reasonable and effective intrinsic safety comprehensiveevaluation indexes system.This thesis takes the coal mine safety as the main purpose and has a higher level miningof coal intrinsic safety based on the recent Man-Machine-Environment research, whichobtains that safety culture and information make different in the coal mine safety productionand accident prevention. Therefore, compared with original system, add the safety culture andinformation two evaluation units and separately analyze the present existing defects, finallymake some corresponding measure.Based on the present coal mine safety evaluation index system, combined with the coalmine fact, establish intrinsic safety evaluation index system. In the index system, it consists of6first indexes,19second indexes and58third indexes. Based on the expert estimation, adoptthe AHP (Analytic Hierarchy Process) to compute the weights of intrinsic safety coal mineindexes, and by the given proportion quotiety determine the relative importance between twoelements to construct judgment matrixes，which converts many complicated and obscuredrelationship into quantitative analysis.Finally, establish coal fuzzy comprehensive evaluation model and apply it in SongZhuang coal mine And obtain the evaluation results Combined with the intrinsic safety degree,the mine belongs to degree Ⅳ, and according to the evaluation result, put forward some detailconstruction measures.
