摘　　要：在铁路隧道穿越含煤地层时,正确预测煤与瓦斯危险性是隧道建设的安全保障之一。本文分析研究了瓦斯测试法的原理、方法,通过对贵(阳)广(州)铁路贺州段的7个隧道的瓦斯测试,结合地质、煤层、煤质成果,判明煤与瓦斯危险性程度,提出预防煤与瓦斯突出的可行性建议,为隧道建设的超前预测提供较可靠的地质依据。Prediction of the coal and gas risk is one part of tunnel security, when the railway tunnel through the coal-bearing strata. The principles and methods of gas measurement was analysis and applied to seven of the gas tunnel testing in Guiyang-Guangzhou tunnel, this work combined with geological, coal, coal quality to identify the danger of coal and gas outburst, provided a more reliable geological basis for the tunnel construction, the prevention of coal and gas outburst was proposed.

关 键 词：隧道 煤与瓦斯突出 超前预测
