黄瓜山隧道瓦斯防治措施探讨

On exploration for gas prevention measures in Huangguashan tunnel

以永江高速一标黄瓜山低瓦斯隧道工程为例,对隧道穿越煤层段瓦斯的预防、监测和防治方案进行了探讨,并经实践证明,此方案对瓦斯隧道的施工是可行的,在瓦斯控制方面取得了良好的效果。

Taking the Huangguashan low gas tunnel project along 1 st Section of Yong-Jiang Expressway as the example, the paper explores the gas prevention, the supervision and the treatment for the tunnel crossing the coal layer section, and proves by the practice that the scheme is feasible for the construction of the gas tunnel, so it can achieve better effect for the gas control.
