The Study On Security Optimization Analysis Of Mine Ventilation System

Mine ventilation system is an important part of mine production system, is in charge of continuously supplying fresh air, discharging poisonous and harmful gases, ensuring the life of mine and homework person's safety, so the safety of ventilation system is of vital importance for the mine safety. Studied the relationship of the stability, reliability and security of mine ventilation system, based on analyzing the condition of system optimization, the feature of multi-objective optimization solution and its basic solving method, meanwhile, referred on the safety and basic requirements of mine ventilation system.Applying the related knowledge of system optimization, established the safety index and index ratio of mine ventilation system. Among establishing each index weight of safety index system, using constructing judgment matrix method and based on the expert evaluation experience weight, constructed the relative importance of each index. Through the analysis of ventilation system's safety, timely discovered the possible fault and the accident hidden dangers, which existed in the process of system operation, and provided scientific basis for mine ventilation system design and management, found a more comprehensive and reasonable index for the overall or unit performance evaluation of ventilation system, finally can effectively prevent and reduce the accidents of mine ventilation system.Ventilation system is a complex system. This thesis analyzed the effectiveness of air quantity and the rationality of the ventilation system, from mine ventilation resistance measurement and the actual situation of ventilation roadway. Mainly aimed at the security of mine ventilation system, studied the security of mine system from the actual conditions of mine ventilation system, ventilation network connection, ventilation, the facilities of controlling ventilation, etc..
