摘　　要：良好的通风系统是保证高瓦斯隧道施工顺利进展的关键。该文以某高瓦斯为例,针对高瓦斯现状及施工难点,从通风设计原则和标准着手,对通风方案进行综合制定,并对不同施工阶段的风量进行计算。基于此,对不同阶段隧道通风系统的主风机进行选型,并对隧道交叉口及主要通风汇流处射流风机进行布设。该文旨在为类似工程施工工艺制定提供参考。A good ventilation system is the key to ensure the smooth progress of high gas tunnel construction.In this paper,taking a high gas as an example,aiming at the current situation of high gas and construction difficulties,starting from the ventilation design principles and standards,the ventilation scheme is comprehensively formulated,and the air volume in different construction stages is calculated.Based on this,the main fans of the tunnel ventilation system at different stages are selected,and the jet fans at the tunnel intersection and the main ventilation confluence are arranged.This paper aims to provide reference for the formulation of construction technology of similar projects.
