Structure and method for reinforcing walls filled in gob-side retained tunnel by arranging three-dimensional reinforcing ribs in walls

Abstract

The invention relates to a structure and a method for reinforcing walls filled in a gob-side retained tunnel by arranging three-dimensional reinforcing ribs in the walls. The structure comprises walls filled in a gob-side retained tunnel and the latticed three-dimensional reinforcing ribs which are arranged in the walls. Because the latticed three-dimensional reinforcing ribs are arranged in the walls, the slip of the walls is restricted, the walls beside the gob-side retained tunnel are reinforced, the integral walls formed by filling and combining are firmer, the deforming and sliding resisting ability of the walls is greatly improved, the inward sliding of the walls beside the gob-side retained tunnel is effectively prevented, the cross section of tunnel behind the gob-side retained tunnel is effectively maintained and the safety of the gob-side retained tunnel is ensured. The structure is simple and is easy to construct, and the method is convenient, safe and reliable, thus the structure and the method are widely practical.

Description

technical field [0001] The invention relates to a structure and a method for reinforcing the filling wall of gob-side entry retaining with built-in three-dimensional reinforcing ribs, and is especially suitable for strengthening the filling wall of mining underground mining roadways in mines. Background technique [0002] The technology of gob-side entry retention has been used in the world mining field for quite a long time. Its essence is to use the method of supporting wooden pillars, masonry gangue belts or filling concrete in the mining roadway behind the mined working face along the gob. The area is reserved as the recovery roadway of the next working face. [0003] With the continuous development of science and technology and mining mechanization, it is more and more common to use masonry to fill the wall of the gob-side entry retaining. At the same time, it bears the lateral pressure during the roof rotation process of the masonry beam structure formed after the old...

AI Technical Summary

Problems solved by technology

Although the above method can reduce the deformation and slippage of the filling wall, it is still difficult to effectively control the displacement of the wall. Therefore, how to ensure the integrity of the filling wall and improve its bearing capacity is a major safety production problem that needs to be solved urgently.
