Daxing mine with three specific conditions, the Daxing Mine geological conditions, storage conditions and other factors, identified through economic comparison of the mine shaft using pioneering approach. Single-level layout, layout of the two rock roadway, which winds back to a main roadway, and the other one is transportation roadway. Seam roadway were used to the wind, to bring the district into coal and popular person. Because the average coal seam inclination is relatively small, determined through the analysis and comparison of the tilt longwall mining method. This method roadway layout simple, high efficiency, coal out fast, more reasonable. Mine ventilation identified alongside the central ventilation, ventilation shaft ventilation extract used to meet the requirements of the ventilation shaft. Skip the main shaft used to upgrade and meet the demands of coal upgrading. Finalization of the drainage, electricity and other parts of the design elements. This design comply with the relevant laws and regulations, and meet the national security requirements of the standard production Key word: Vertical shaft； Single leve；incline long wall mining coal；central compound -like ventilation II
