摘要
以兰海高速重庆至遵义段某高瓦斯公路隧道为工程背景,针对该高瓦斯公路隧道穿越薄煤层群的特殊工况,结合实际煤层群分布特征及煤层瓦斯参数,提出了一套完善的安全施工技术并进行了工程实践,确保该隧道安全施工穿越了煤系地层,该技术可为同类型瓦斯隧道施工提供一定的佐证。
Taking a high gas highway tunnel in the section of Lanhai Expressway from Chongqing to Zunyi as the engineering background, a set of perfect safety construction technology is proposed for the specific situation of high gas highway tunnel crossing thin coal seam group, combined with the actual coal seam group distribution characteristics and coal seam gas parameters. The feasibility of this technology was also verified during the tunnel construction process. This technology can provide some evidence for the similar gas tunnel excavation.
