Abstract：
In order to solve some key challenges in the construction of railway gas tunnels, especially tunnels with
gas bursts, a comparative study on the problems related to the existing specification, design, construction and man?
agement is conducted based on the construction practice of a gas burst section of the Tianping tunnel on the Chongq?
ing-Guizhou railway and experience with similar coal mining projects. Suggestions such as optimization of grading
for gas tunnels, establishing observational evaluation systems and organization and management modes are proposed.
