Safety Evaluation And Application Of Coal Mine Power Supply System

Coal mine power supply safety is the guarantee of mine safety production.There are many kinds of power supply system equipment,and the operation process is complicated.The human,environmental and management are intertwined,and the power supply may be unsafe or even cause accidents.Safety evaluation is to prevent accidents.However,the commonly used power supply safety evaluation methods mostly use qualitative evaluation methods.Therefore,it is necessary to study more scientific and reasonable evaluation methods.In the article,the domestic and international safety evaluation theory,the development status of coal mine safety evaluation technology and the characteristics of evaluation methods are summarized.Based on the analysis of the characteristics of coal mine power supply system,the factors aff,ecting the safety of coal mine power supply are summarized.Establish a coal mine safety evaluation index system by using analytic hierarchy process.Then the analytic hierarchy process and fuzzy comprehensive evaluation are combined to construct a fuzzy comprehensive evaluation model based on analytic hierarchy process.Through accident statistics and on-site investigation,the assignment of weights is more scientific and reasonable,and better reflects the importance of various factors to,the safety status of coal mine power supply systems.The safety evaluation model of the coal mine power supply system studied was applied to the power supply evaluation of Dongdong Coal Mine.Combined with the characteristics of the power supply system of the mine,the safety evaluation was carried out and the comprehensive safety evaluation results were obtained.The evaluation results verify the correctness and scientificity of the given coal mine power supply system safety evaluation model,which can be applied in the safety evaluation of the power supply system of coal mine enterprises.
