Anti-seismic support method for mine shaft

An anti-seismic support method for a mine shaft, comprising:

• providing a circular support groove in a liquefaction-prone layer of the mine shaft;
• providing a plurality of horizontal support holes along a radial direction in a groove wall of the circular support groove, fixing an outer support spring steel cylinder against the groove wall, and providing a horizontal transverse anchor rod group to fix the outer support spring steel cylinder;
• drilling vertical support holes at a groove bottom of the circular support groove, anchoring a vertical anchor rod group into the vertical support holes, and injecting an expansion anchoring slurry into the vertical anchor rod group to expand an expansion open end;
• making a lower positioning support ring abut against and be supported on an upper end of the vertical anchor rod group, and making the lower positioning support ring abut against an inner wall of the outer support spring steel cylinder;
• connecting and fixing an anti-seismic connecting rod group between the lower positioning support ring and an upper positioning support ring;
• welding an inner support spring steel cylinder to an end of the horizontal transverse anchor rod group fixedly, and making an outer wall of the inner support spring steel cylinder abut against the upper positioning support ring and the lower positioning support ring;
• and
• providing an upper support cover seat at a top of the outer support spring steel cylinder and the inner support spring steel cylinder, and providing an anchoring layer on a wall of the mine shaft located below the inner support spring steel cylinder.
