摘要
兰渝铁路梅岭关隧道DK607+800～DK610+050、DK613+350～DK614+950段按高瓦斯设计,但瓦斯爆炸的机理较为复杂,爆破时产生的冲击波、气体产物、炽热的固体颗粒都可能参与瓦斯的发火反应。文章针对梅岭关隧道瓦斯地层的特点和危害,主要论述了在隧道爆破施工中瓦斯隧道的安全问题及其处理措施。
Sections of DK607＋800～DK610＋050 and DK613＋350～DK614＋950 of Meilingguan tunnel on Lanzhou-Chongqing railway were designed according to the tunnel with rich gases.While the mechanism of gas explosion is very complex,shock wave,gaseous products and hot solid particles may be involved in the ignition reaction of gas.In view of the characteristics and harm of gas stratum in Meilingguan tunnel,the paper discusses the safety countermeasures for the blasting operation in the construction of the tunnel.
