我国矿产资源丰富,地下蕴藏着大量的煤炭。隧道穿过煤层,瓦斯溢出,达到一定浓度极易发生瓦斯爆炸,危及人民财产安全。高瓦斯隧道施工与普通隧道最大的区别在于要充分考虑瓦斯的危害,保证整个施工过程中的施工安全。文章基于高瓦斯隧道施工实践,从高瓦斯隧道的瓦斯测点布置、瓦斯检测方法、各工序施工技术等方面做了全面阐述,并指出了解决办法。
Our country is rich in mineral resources, underground holds a large amount of coal. Tunnel through the coal seam, gas overflow, reaching a certain concentration of gas explosion prone to endanger the safety of people’s property. The biggest difference between high-gas tunnel construction and ordinary tunnel lies in fully considering the hazards of gas and ensuring construction safety throughout the construction process. Based on the practice of high gas tunnel construction, this paper comprehensively elaborates the layout of gas measuring points in high gas tunnels, gas detection methods and construction techniques of each process, and points out the solutions.
