【摘要】：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。
[Abstract]:In order to grasp and control the danger of gas emission, combined with the theory of gas flow in coal seam, the law of gas emission during tunneling is analyzed, and the calculation method and control measures of the intensity of gas emission in gas outburst tunnel are put forward. It is pointed out that gas drainage is an important measure to control the intensity of gas emission in gas outburst tunnel. The research results show that the intensity of gas emission can be controlled within 0. 5 m~3/min after adopting reasonable and effective measures to control the intensity of gas emission, and the construction safety of gas outburst tunnel can be greatly improved.
