Abstract: A tunnel is an important structure of the highway.It will cover a great amount of coal resources when going above mining areas.It is in urgent need to harmonize between exploring the covered coal and construction of the tunnels.Accordingly,beginning with the study of the tunnel lining structure,the surrounding rock grade and the design parameter,the ability to resist the mining influence of tunnels themselves is analyzed.Besides,a technical system of resisting the mining influence in highway tunnels is provided based on the analysis of the tunnel initial support,the secondary lining,the inverted arch and water-proof layer materials.A series of measures are taken to ensure the operation safety of tunnels and exploring the covered coals.

Key words: Coal mining, Tunnel lining structure, Resistance to deformation system
