摘　　要：针对自然风压对通风系统的复杂影响,以会宝岭铁矿为研究对象,利用Ventsim软件,采取将各条进回风井分离并计算每条进回风井的分支风压的方法进行解算,部分联络巷分支的敏感度受自然风压的影响较大,找出分支风量对自然风压的敏感度大的区域,在季节变化时应进行重点监测,采取相应措施避免事故的发生。同时分析不同季节自然风压对通风系统的影响效果,分析表明自然风压单独作业时,冬季进风量不能满足矿井的正常需风量,当和风机共同作用时,夏季阻碍矿井通风,冬季、春季和秋季帮助矿井通风。In view of the complex influence of natural wind pressure on the ventilation system, taking Huibaoling iron mine as the research object, using Ventsim software, take the method of the branch pressure into the back shaft separation and calculate each return shaft the calculation part, the natural wind pressure has a greater influence on sensitivity of the crossheadings branch, then find out the area where the branch air is sensitive to natural wind pressure, the seasonal changes should focus on monitoring, take appropriate measures to avoid accidents. At the same time, analyse the different seasonal influence on natural wind ventilation system, analysis shows that the natural wind alone, winter air can not meet the normal needs of the air volume, and fan interaction when summer, hinder mine ventilation, winter, spring and autumn help mine ventilation.
