With the coordinated development of social economy and technology today, various advanced construction techniques and well-established management measures have begun to be widely used in coal-tunnel construction. However, in the construction process of low-gas tunnels, it will also cause a certain degree of adverse impact on the construction quality and safety due to the lack of technical experience and management experience to a certain extent. Based on this, this paper takes the actual tunnel project of a coal mine as an example to analyze the main construction technology and safety management measures of low-gas tunnels, so as to provide guarantee for the quality and safety of such tunnel construction.
