Abstract： Huodong mining area belongs to the national coal planning mining area. The coal seam data of 33 mining areas, 3 exploration rights, 34 mining rights and 10 closed mines in the mining area were integrated and sorted out, and the coal seam continuity was compared and analyzed. The research results showed that the No.3 coal seam of Shanxi Formation was the main coal seam, and the condition was better than that of No.2 coal seam. The No.10 coal seam of Taiyuan Formation was the main coal seam, and the conditions were better than No.9 and No.11 coal seams. The research results provided an important basis for the development and utilization of coal mines and the overall planning of the mining area in Huodong mining area.
