穿越非煤系地层的隧道中的瓦斯的不可预见性很大，非煤系构造连通型瓦斯隧道是穿越非煤系地层的典型代表，现阶段对这类隧道还没有系统的超前地质预报技术，给施工安全造成了很大的威胁。为了准确预报非煤系构造连通型瓦斯隧道中的瓦斯运移途径，避免安全事故的发生，通过对现有超前地质预报技术包括地质法和物探法在非煤系构造连通型瓦斯隧道中适用性的分析，构建非煤系构造连通型瓦斯隧道的综合超前地质预报体系，并通过在肖家梁铁路隧道施工中成功应用，说明提出的超前地质预报技术是可行的。

The gas in the tunnel through non-coal strata can hardly be predicted. Fracture connectivity type tunnel in non-coal strata is a typical representative of such tunnels. At the present stage, there is no systematic geological prediction technology for such a tunnel, which brings a big threat to construction Safety. In order to accurately forecast the gas movement in fracture connectivity type tunnel and prevent security incidents, this paper, through the analysis of the applicability of advance geological prediction including geological method and geophysical method, puts forward a comprehensive geological prediction system with reference to the successful application in Xiao Jiang Liang fracture connectivity type tunnel in non-coal strata, which has proved the feasibility of the advance geological prediction.
