摘　　要：随着我国基础交通的建设和发展,穿越煤系地层的隧道越来越多,隧道施工瓦斯灾害事故也在不断的增加。因此,人们越来越认识到防范和减轻瓦斯灾害的重要性,迫切需要寻求有效的隧道瓦斯灾害危险性评价方法与手段。根据洛湛铁路长乐隧道和袍子岭隧道现场施工的特点,确定了其施工通风方式,通过对污染源的分析和对风量、风压的计算,设计了较为合理的通风系统,保证高瓦斯隧道的施工安全,对类似瓦斯隧道施工通风具有借鉴作用。Because of more and more tunnels passing through coal-bearing strata,gas accidents are on the rise accompanying with the construction and development of basic communications in China.Therefore,it is so urgent to realize the significance of preventing and mitigating the gas disaster,and an effective risk assessment method for gas disaster should be established.The construction ventilation option for the access tunnels in Luo-zhan Railway is determined by the features of Changle and Baoziling Tunnel.Based on the analysis of pollution sources and the calculation of wind volume and pressure,a reasonable ventilation system is designed,which could provide references for the ventilation in the construction of same gas tunnels.
