Abstract: In view of the issue on the temporary reconstruction of deep vertical shaft in the western mining area，and taking the diagonal arrangement of the main shaft，auxiliary shaft and ventilation shaft in Tashidian NO.1 coal mine，Sinkiang for example，the main factors influencing the temporary reconstruction were analyzed，and the temporary reconstruction of deep vertical shaft was optimized with comprehensive comparison of alternative methods.Results indicated that diameter of shaft，hoisting capacity，hoisting equipment and lifting time are the main factors influencing temporary reconstruction; Selecting main shaft and ventilation shaft for temporary reconstruction and permanent equipment for auxiliary shaft can meet the needs of the hoisting capability for roadway driving engineering; Temporary reconstruction of main shaft appropriately adopts a pair of 1.5 t mine car with double-deck single car as temporary cage;Temporary reconstruction of ventilation shaft can draw lessons from the successful experience of metal mine，and adopts the double-hook mix hoisting way equipped with a 3 m3 skip and a 1 t double-deck cage.The research has a guiding role in accelerating construction speed and reducing the constructing period for Tashidian NO.1 coal mine.At the same time，it provides the reference for temporary reconstruction of deep vertical shaft in Sinkiang and other western mining areas.
