According to the rules of deformation of the surrounding rock of tunnels, this paper analyzes the factors influencing the maintanence of tunnels in floor rocks, i.e. the extraction of the upper coal seam, the mechanical properties of surrounding rocks, the vertical distance between the tunnel and the upper coal seam, as well as the horizontal distance between a tunnel and the edge of coal pillar in upper seam. The reasonable layout of tunnel below longwall face is described.
