Optimization And Analysis On Evaluation Of GaoJiaLiang Coal Mine Ventilation System

Mine ventilation is the key factor to ensure the safe production of the mine.In order to ensure the safety of the mine production,it is necessary to keep the mine ventilation system in the Optimal state.In this paper.Evaluation of mine ventilation system,it is advantageous to find out the bad factors in the ventilation system,and take appropriate measures in time,to ensure that the ventilation system can meet the requirements of mine safety production,prevent the occurrence of the safety accident of the ventilation system.This article from the following 4 aspects to establish the evaluation system of GaoJiaLiang coal mine ventilation system index,which are the ventilation system environment,the ventilation power and facilities,the rationality of the ventilation mode,the rationality of the ventilation network,clarify the significance of each evaluation index and calculation method.The principle of membership function and the construction method and type of membership function are introduced,and the membership function of each evaluation index is given,and use the improved analytic hierarchy process to calculate the mine ventilation system criterion layer and the weight of the factor layer,finally,the comprehensive treatment method is given.This article from the reality of GaoJiaLiang coal mine,the resistance of GaoJiaLiang coal mine ventilation system and determination of ventilator performance,the fuzzy comprehensive evaluation method is used to evaluate the index system established,the overall situation and existing problems of the mine ventilation system are obtained.According to the problems existing in the system,the optimization scheme is put forward,and the optimization scheme is simulated and predicted by using the integrated management system of mine ventilation.
