Description

Technical Field

[0001] The present invention relates to the technical field of mine support, in particular to a non-metal underground mine support construction reinforcement structure and a construction method thereof. Background Art

[0002] In non-metallic underground mining operations, tunnel support, as a key component in ensuring safe mine production, has always been closely linked to the characteristics of the ore and rock and mining requirements. Currently, the ore and rock encountered in underground non-metallic mining often have significant characteristics such as low hardness, well-developed joints and fissures, and softening upon contact with water. This places stringent demands on the adaptability, integrity, and reliability of the support structure. However, existing support technologies have exposed numerous structural flaws in practical applications, particularly in the overall design of the support system.

[0003] According to the patent document: CN218894664U, a mine tunnel support structure is disclosed, which relates to the field of tunnel support technology. The utility model discloses a mine tunnel support structure, including a base, the top of the base is provided with a support mechanism for supporting and protecting the mine tunnel, and the bottom of the base is fixedly installed with a universal wheel. The utility model drives the threaded rod to rotate by a knob, and the threaded rod is engaged with the threaded sleeve to vertically move the threaded sleeve, the movable plate and the limit rod, so that the anchor rod is inserted into the tunnel ground to fix the support device, so that the support device is fixed, the movable plate is in contact with the ground of the tunnel, and the knob and the threaded rod are continued to be rotated to make the support mechanism rise, so as to facilitate the support and protection of tunnels at different heights, and the top surface of the first support top plate is in contact with the top surface of the tunnel, and the second support top plate and the first support top plate are used to provide double-layer protection, thereby improving safety.

[0004] Existing support structures are generally only arranged at a single point on the inner wall of the tunnel. For example, U-shaped steel brackets are simply used to independently fix the support units to the tunnel rock wall. There is a lack of effective mechanical connection mechanism between adjacent support structures. This "island-style" support method causes the entire support system to present a discrete feature. When a single bracket is subjected to a large axial load caused by the deformation of the mine rock, local damage is very likely to occur due to the lack of coordinated force support from adjacent structures. What is more serious is that this local damage will produce a chain reaction. Other brackets connected to the damaged bracket will be gradually pulled and deformed due to the lack of rigid connection, which will lead to continuous failure of the support system. To this end, we propose a non-metallic underground mine support construction reinforcement structure and its construction method. Summary of the Invention
