A designed net diameter of a new mine air returning shaft in Zhaozhuang Mine was 8.6m ,a depth of the mine shaft was 428.35m and a construction period required was 330 days.A comparison collection was conducted on the three feasible construction alternatives of the mine shaft ,an optimized alternative was determined and was pre-grouting at the surface ground and reaming of raise boring.The month shaft completed rate of the construction alternative would be over 150m and the cost could be reduced by about 1/3 lower than conventional construction method.The construction alternative could have a safety construction ,simple operation ,easy equipment movement ,low labor intensity and high efficiency.When the construction alternative applied to the construction of the mine shaft ,a safe-ty ,excellent quality and rapid construction were realized ,an actual construction period was 10 days earlier than the schedule construction period and a good effect was obtained.
