为掌握和控制瓦斯涌出的危险性，结合煤层瓦斯流动理论，分析隧道掘进时瓦斯涌出的规律，提出瓦斯突出隧道瓦斯涌出强度的计算方法及控制措施，并指出瓦斯抽放是控制瓦斯突出隧道瓦斯涌出强度的重要措施。研究结果表明： 采取合理有效的瓦斯涌出强度控制措施后，掘进工作面瓦斯涌出强度可以控制在0.5 m3/min以内，可以极大地提高瓦斯突出隧道的施工安全性。

During the construction of gas outburst tunnel, the dynamics of gas outburst are often difficult to master and control; but it is the top priority of the safe construction of gas outburst tunnel. In this paper, the gas flow theory of coal seam is studied; the gas outburst rules of the tunnel are analyzed; the calculation methods and control methods for gas outburst intensity are proposed; meanwhile, it is pointed out that the gas drainage is the most important key to gas outburst intensity control. The study results show that the gas outburst intensity of tunneling face is effectively controlled within 0.5 m3/min and the construction safety of the gas outburst tunnel can be significantly improved by carrying out rational gas outburst control methods.
