摘　　要：随着我国西南地区公路建设事业的高速发展,许多瓦斯隧道将要或正在建设,为保证瓦斯隧道施工安全,故提前对隧道掌子面前方瓦斯参数及瓦斯等级的判定就尤为重要.论文紧密结合渝湘复线高速公路鹿角高瓦斯隧道的建设,通过对隧道二叠系下统梁山组(P1l)煤层瓦斯参数测定及绝对瓦斯涌出量的测定,系统总结瓦斯隧道瓦斯工区等级的判定及突出危险性的预判,对瓦斯隧道施工提供了准确的依据,具有指导价值.With the rapid development of highway construction in southwest China,many gas tunnels will be constructed or are under construction,in order to ensure the safety of gas tunnel construction,it is particularly important to determine the gas parameters and gas level in front of the tunnel face in advance.This paper closely combines with the construction of the Lujiao High-Gas Tunnel of the Yuxiang Double Pipeline Expressway,systematically summarizes the determination of the grade of gas tunnel gas work area and the prediction of projection risk by measuring the coalbed gas parameters and absolute gas emission rate of the lower permian liangshan formation(P1l)of the tunnel,and provides accurate basis for the construction of the gas tunnel and has guiding value.
