Abstract：In order to ensure a continuity and construction speed of the secondary phase mine roadway engineering construction in Zhaoxian Mine ,based on the analysis and consideration on the mine actual conditions ,a winch not temporarily changed plan was provided. That is when the mine air returning shaft reached at the bottom of the mine shaft ,the previous hoisting system were not be changed and the kibble hoisting would be continuously applied. The auxiliary transportation system in the under‐ground mine was changed from the railway mine car to the trackless rubber -tyred vehicle. The paper had an analysis and comparison on the mine roadway engineering workload and construction period , hoisting efficiency , safety and economic aspects. The results showed that a winch not temporarily changed could reduce 200 m of the mine roadway workload ,reduce the mine construction period for 115 days and save the cost of RMB 6.56 millions. The safety would be reliable in the same ,thus the plan of the winch not temporary changed was determined and applied and the expected effect was ob‐tained.
