Embodiment Construction
[0032] The invention will be further described in detail below in conjunction with the examples, but the embodiments of the invention are not limited thereto.
[0033] The double buffering protection method for the shaft wall of the mine shaft provided by the present invention specifically includes: determining the range where the ore collides with the shaft wall for the first time; carrying out side expansion excavation on the collision position of the shaft wall to form a step; Anchor rods are pre-embedded on the slope, and the ends of the anchor rods are threaded; hard polyurethane foam boards and manganese steel plates with grids are respectively arranged on the platform surface of the steps and the slope surface, as a flexible buffer layer and wear-resistant layer, ensuring that each There are anchor rods in the grid; the rigid polyurethane foam board and the manganese steel plate with grid are fixed with nuts, and a certain prestress is applied.
