Embodiment Construction

[0035] In order to better understand the present invention, the technical solution of the present invention will be described in detail below with specific examples, but the present invention is not limited thereto.

[0036] The technical scheme of the support method of the gob-side entry retaining block and tenon structure wall is as follows:

[0037] ① The ground of concrete block 1 and block 2 is prefabricated through molds, the internal structure and size are the same, and the interior is welded with steel bars 6

[0038] ② Transport block 1 and block 2 to the underground construction site by special vehicles.

[0039] ③ Every time the working face is advanced by 3 to 6 meters, the bottom plate near the side of the goaf outside the end support 3 is cleared to a hard bottom, and the cement sand ash is tiled to form the foundation of the wall 5, and blocks are placed staggered along the longitudinal direction of the roadway 1. The end is filled with blocks 2 and 2, and ...

Abstract

The invention relates to a method for supporting a gob-side entry retaining building block coak structure wall, and provides a laneway's side supporting method which is convenient in construction. By the method, a trave hollow wall constructed by concrete building blocks and coaks replaces a heavy concrete wall to support a gob-side entry retaining laneway's side, consumption of materials is reduced, labor intensity is decreased, the constructed wall can advance following a working face, after being constructed, the wall can be connected with a roof immediately so as to effectively support the roof, and the supporting strength for a tunnel is increased.

Description

technical field [0001] The invention relates to the technical field of mine excavation, in particular to a method of using concrete blocks to buckle and mortise and tenon well lattices to build a hollow wall body to carry out side support of gob-side retaining lanes. Background technique [0002] Gobside retaining is an important technical measure to alleviate the continuous tension of mining, increase the recovery of coal resources, reduce the rate of excavation, and improve the productivity of mine labor. The key to determining the success of gob-side entry retention is the support of the side of the goaf. At present, the way of supporting the side of the gob-side entry is generally to build a closed concrete wall or a solid block wall. This support method consumes a lot of materials, consumes a lot of man-hours, and uses complicated equipment, which seriously affects the normal production of the working face. Contents of the invention [0003] In order to overcome the ...
