Abstract: The study takes a vertical shaft in the water-bearing fragmented section as the engineering background,carries out drill core geological survey,and analyzes the stability of the shaft wall rock in -1 000--1 200 m  according to the stability diagram based on rock geological mechanical classification,in order to provide basis and reference for the plan making of shaft construction and in-service wall rock stability control.The concrete wall of the shaft wall rock in the water-bearing fragmented section is calculated,the new shaft wall rock support designs are proposed,and the deep vertical shaft support design notion of pressure-free concrete shaft is determined.The exposed height of excavation work face is increased to fully release the shaft wall rock pressure.Then,the shalt is supported by temporary support+concrete shaft wall structure and the effect is monitored in real-time.The results show that the support means can make it through the shaft water-bearing fragmented section.
