摘要
内昆铁路青山隧道施工中遇到了多工作面施工、瓦斯涌出和揭煤等不同的施工难题,对施工通风提出了新的要求。青山隧道的施工通风将射流通风技术应用于施工通风中形成了射流通风新模式,有效地解决了隧道5个工作面同时施工、无轨运输等条件下的快速掘进问题,较传统的巷道式通风显示出了很大优势。
Due to the special construction difficulties of Qingshan tunnel, such as construction at multiple working faces, gas emission and coal-exposing construction, there are high requirements for the construction ventilation of the tunnel. During the construction of Qingshan tunnel, jet ventilation technology is applied and new jet ventilation mode is formed, which effectively meet the requirements of simultaneous construction at five different working faces and trackless transportation system adopted in the tunnel construction. Jet ventilation technology has great advantages over traditional gallery ventilation technology.
