Research On Health Evaluation Of Ventilation System In Shuangma Mine

Healthy mine ventilation system is the basis of ensuring safe production.In order to make the mine ventilation system more suitable for the development of mine production,we must scientifically,reasonably and comprehensively evaluate the mine ventilation system,and then find and solve the problems of mine ventilation system.In order to make the health status evaluation of mine ventilation system fully reflect the comprehensive situation of the evaluated object,taking Shuangma mine ventilation system as an example,this paper analyzes the main influencing factors of the health status of mine ventilation system by combining field investigation and theoretical analysis,and the comprehensive evaluation index system was constructed,as well as determines the comprehensive weight of the main influencing factors based on analytic hierarchy process,sequence relation method and expert investigation method,On this basis,the health evaluation standard of mine ventilation system is established,and its application results are analyzed.The main research results are as follows:(1)From the perspective of ventilation power,ventilation network and ventilation facilities,the main influencing factors of the health status of Shuangma mine ventilation system are analyzed,and the evaluation index system of the health status of mine ventilation system is established;(2)Contrast analysis of the analytic hierarchy process(ahp),order relation analysis method and expert investigation weighting method in determining the Shuangma mine ventilation system health status,main factors affecting the weight of the difference of the results on the basis of the mine ventilation system was put forward the main factors that influence the health comprehensive weighting method,and through the case analysis to verify the feasibility of integrated weighting method;(3)The index system of health status of Shuangma mine ventilation system and the membership degree function of each index are constructed,the grade division standard of each index of health status of mine ventilation system is established,and the rapid analysis method of using a few but very important indexes to evaluate the health status of mine ventilation system is put forward;(4)Based on the rapid evaluation method,analytic hierarchy process(AHP),order relation method and expert survey weight method,the health status of the mine ventilation system in Shuangma Mine is comprehensively evaluated,and the main problems and countermeasures of the mine ventilation system in Shuangma Mine are put forward.
