Embodiment 1

[0049]This embodiment provides an access-type cemented and filled sealing wall, which includes a sealing wall body and a reinforcing component, which is arranged inside the sealing wall body, including reinforcing ribs arranged in a staggered manner and the reinforcing ribs Compatible stiffeners. The reinforcing rib and the reinforcing plate play a basic role of reinforcement inside the sealing wall. In this embodiment, the reinforcing rib includes a reinforcing anchor rod 2 and a vertical rib 5, wherein the reinforcing anchor rod 2 runs through the sealing wall body and its The two ends extend to the outside of the wall body; the vertical bars 5 are arranged inside the block wall body and intersect with the anchor rods. Reinforcing the anchor rod 2 and the vertical rib 5 improves the bending resistance of the sealing wall; the reinforcement part inside the sealing wall is very stable. Specifically, the reinforcing anchor rod 2 and the vertical bar 5 can be selected from No. ...

Embodiment 2

[0054] This example provides Figure 1-3 The construction method of the road-type cemented-fill sealing wall shown includes,

[0055] Pretreatment, clean up the ground of the stope to the solid bottom;

[0056] For reinforcement, use a drilling rig to set reinforcement anchor holes on both sides of the surrounding rock 7. The depth of the reinforcement anchor holes is 800mm, and the height of the stope ground is 500mm. The first hole is constructed. The distance from the third hole is 1m, and the quantity is 3 on both sides (total 6). It is required that the anchor holes on both sides can be connected into a line at a horizontal height; Use a drilling rig to construct formwork anchor holes at 275mm on both sides of the front and back of the rod eye. The hole depth of the formwork anchor holes is 500mm, and the height from the bottom plate is 500mm. Construction of the first hole, the first hole and the second hole, the second and the second hole The height of the three holes...

Embodiment 3

[0062] This embodiment provides a method for constructing an approach-type cemented filling sealing wall for a stope with fractures, including:

[0063] Pretreatment, cleaning the ground of the stope, clearing to the solid bottom, pre-spraying to prevent the slurry from running out during filling, and laying steel mesh at the position corresponding to the bottom of the vertical formwork wall, with a mesh degree of 400×400.

[0064] For reinforcement, use a drilling rig to set reinforcement anchor holes on both sides of the surrounding rock 7. The depth of the reinforcement anchor holes is 800mm, and the height of the stope ground is 500mm. The first hole is constructed. The distance from the third hole is 1m, and the quantity is 3 on both sides (total 6). It is required that the anchor holes on both sides can be connected into a line at a horizontal height; Use a drilling rig to construct formwork anchor holes at 275mm on both sides of the front and back of the rod eye.

Abstract

The invention discloses an inlet type cementing filling blocking wall and a construction method thereof. The blocking wall structure comprises a wall body, and further comprises a reinforcing assemblyand a capping part, wherein the reinforcing assembly is arranged in the blocking wall body, and comprises reinforcing ribs arranged in a staggered manner and a reinforcing plate attached to the reinforcing ribs; and the capping part is arranged at the top of the blocking wall body. According to the blocking wall, a formwork construction method of combining the reinforcing ribs with the reinforcing plate is adopted. The problem that the structure and the parameter setting of a mine filling blocking wall adopting a filling mining method are unreasonable is solved, and through practice verification, under the condition that the filling is more economical and reasonable compared with the prior art, the filling blocking wall can bear the acting force from the filling material on strength, andcan also meet the requirements of resisting the blasting vibration of the mining area and filtering water of the filling material slurry in structure.

Description

technical field [0001] The invention relates to the technical field of underground mining, in particular to an approach-type cemented filling sealing wall and a construction method thereof. Background technique [0002] Compared with other mining methods, the cemented filling mining method performs better in preventing surface subsidence and controlling ground pressure activities, and has a higher ore recovery rate, which not only reduces the accumulation of mine waste on the surface, but also releases a large amount of ground space, while reducing the environmental impact of the mining industry, so it is widely adopted around the world. The construction of the filling retaining wall is a necessary procedure for stope filling. The stability of the retaining wall is related to the progress of the follow-up process and the safe production of the mine. Due to the unreasonable setting of the retaining wall structure in some mines, hollow bricks or wooden boards are used to pil...
