Problems solved by technology

However, the low support strength of wooden stacks and dense pillars cannot meet the needs of most projects. The formwork support of the goaf side of the wall is supported by wooden point columns. This kind of support has low initial support, low compression resistance, and no longitudinal support performance.
However, gangue bags and stone masonry walls cannot be connected to the roof, resulting in excessive sinking of the roof, poor support effect, and failure to apply support force to the roof in time, and failure to provide pre-support in time will easily cause the roof to fall, which will seriously affect production and safety

Embodiment Construction

[0033] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.

[0034] Such as Figure 1-6 As shown, the present invention provides a supporting partition wall 2, which is arranged in an empty entryway 1 of the working face. The lane floor 12 at the bottom of the lane 1 and the lane sides 13 located on both sides of the empty lane 1 on the working face, the lane sides 13 on each side are connected with the lane roof 11 and the lane bottom 12 respectively, and the above-mentioned empty lane 1 on the working face is formed by the lane roof 11 , the lane floor 12 and the lane side 13 that is connected between the lane roof 11 and the lane bottom 12 are formed, and two rows of support between the lane roof 11 and the lane bottom 12 are arranged side by side in the empty lane 1 of the above-mentioned working face. The support columns 21 are poured between two rows of parallel support columns 21 and...

Abstract

The invention discloses a supporting separation wall, which is arranged in the working face ditch retaining. The working face ditch retaining comprises a d The roadsides on both sides of the roadway retaining in the face, the roadsides on each side are respectively connected with the roadway roof and the roadway floor, the working face empty roadway is formed by the roadway roof, the roadway floor and the support connected between the roadway roof and the roadway floor , In the empty alley of the working face, two rows of supporting columns are arranged side by side between the roof and the bottom of the alley, and the concrete layer supported between the top and bottom of the alley is poured between the two rows of supporting columns. The invention also discloses a construction method for supporting the separation wall. The support partition wall can provide pre-support force in time, has good longitudinal support performance and good support effect, and ensures the safety of production and construction. The pouring method is simple, convenient to use, fast in construction speed, high in labor efficiency and good in supporting effect.

Description

technical field [0001] The invention relates to the technical field of mining support walls, in particular to a support separation wall and a construction method thereof. Background technique [0002] In the traditional mining working face, the roadway is kept empty along the working face, and wooden stacks, dense pillars, gangue bags, and stone walls are used as the supporting roof. However, the low support strength of wooden stacks and dense pillars cannot meet the needs of most projects. The formwork support of the goaf side of the wall is supported by wooden point columns. This kind of support has low initial support, low compression resistance, and no longitudinal support performance. . However, gangue bags and stone masonry walls cannot be connected to the roof, resulting in excessive sinking of the roof, poor support effect, and failure to apply support force to the roof in time. Failure to provide timely pre-support may easily cause the roof to sag, which will serio...
