图山寺高瓦斯隧道安全设防综合技术研究

摘要

Targeting on the characteristics of Tushan Temple gas tunnel and the gas haz- ards,the article introduced the gas prevention and control measures taken in Tushan Temple high-gas tunnel construction, proposed the gas safety fortification technology of tunnel struc- ture, and pointed out that the key for gas prevention and control in the high-gas tunnel con- struction is to use the reasonable ventilation method,and the main measure of gas blocking & emission is to set the gas isolation layer and exhaust pipe in tunnel structure, providing the reference for other similar high-gas tunnel engineering constructions.%文章针对图山寺瓦斯隧道的特点及瓦斯的危害，介绍了图山寺高瓦斯隧道施工中采取的瓦斯防治措施，提出了隧道结构的瓦斯安全设防技术，并指出在高瓦斯隧道施工中瓦斯防治的关键是利用合理的通风方式，瓦斯堵排的主要措施是隧道结构设置瓦斯隔离层和排气管，为其他类似高瓦斯隧道工程施工提供了借鉴。
