高瓦斯隧道施工中有毒有害气体的分析

Analysis of Toxic and Harmful Gases in the Construction of High Gas Tunnel

成自铁路白云山隧道在穿越含煤地层段等矿产复杂地质条件下,含煤地层段近煤矿产区有毒有害气体含量超标,论文对隧道施工中出现大量的瓦斯、硫化氢等有害气体进行重点阐述,对隧道穿含煤地层施工中瓦斯突涌中的瓦斯涌出量及其喷出的原因进行分析和分类,提出在隧道施工过程中的预防措施和施工质量的控制方法。

Taking Baiyunshan Tunnel of Chengzi Railway as an example,under the complex geological conditions of coal bearing strata and other minerals,the content of toxic and harmful gases near the coal mining areas in the coal bearing strata of the construction tunnel exceeds the standard.This paper expounds the large number of harmful gases such as gas and hydrogen sulfide appear in the tunnel construction,analyzes and classifies the amount of gas gushing and the reasons of gas gushing in the construction of tunnel through coal-bearing strata,and finally puts forward some preventive measures and construction quality control in the construction process.
