Abstract：Mine shaft is the key to the mine development system.This paper analyzes the problems of poor stability of the surrounding rock of the shaft wall,high water content of ore and rock,easy compaction of materials,and easy formation of wellbore collapse and plugging during blasting.The optimization scheme of arranging double inspection shaft roadway and preventing chute blockage is proposed,and the construction plan of"additional inspection lane+middle section reverse excavation"is adopted.After the implementation,the double inspection roadway spirals up and is arranged in sections around the wellbore of the pass,which is convenient for the inspection during the operation of the pass and the effective treatment measures after the plugging of the well,which can effectively block the groundwater channel and reduce the water damage during the operation of the pass,and the inspection roadway can be used as a ventilation roadway.
