摘要
利用光在不同介质(空气和甲烷气体)中传播光程差,通过光学仪器系统,观测其干涉条纹,判定隧道内甲烷气体的浓度,制定了相应的瓦斯隧道施工技术措施,通过这些技术措施在新且午隧道施工中的应用,确保了隧道施工的安全,并且收到了良好的效果。
It utilizes the transmission optical path difference of the light in different medium（air and methane gas）,according to the optical instrument system,it measures its interferences fringe,judges concentration of the methane gas in tunnel,establishes corresponding methane gas tunnel construction technology measures,according to application of these technology measures in the Xinqiewu tunnel construction,ensures safety of tunnel construction,and gets good effect.
