摘要
以射流通风为主体的通风方式在瓦斯隧道施工中已取得成功,广渝高速公路华莹山隧道和内昆铁路青山隧道的工程实践证明,在平行双孔瓦斯隧道施工中采用射流通风技术能有效地控制风流方向和解决多工作面施工中的通风问题。文章结合工程实例具体阐述了射流技术在瓦斯隧道施工中的应用,并对相关问题进行了探讨。
The construction of Huayingshan tunnel on Huangyu Highway and Qingshan tunnel on Neikun Railway proved that it was very successful to use jet ventilation in gas - contained tunnel. So it is possible to solve the problems of jet direction controlling and multi -face ventilation during the construction of paralleled twin -tube tunnel with this technology.
