Abstract: This paper explored the roadway layout and support in close-distance lower coal seam mining. Combined with the
specific engineering practice, based on the analysis of the layout of the roadway in the lower coal seam mining, it carried out the
analysis and summary of the roadway segmental support design, and analyzed its practical application effect, hoping to provide
reference for the development of similar projects in other mines.

Key words: close-distance coal seam group; lower coal seam mining; roadway layout; roadway support
