Abstract
Description
Technical Field
[0001] This utility model relates to the field of mine support technology, specifically a non-metallic underground mine support construction and reinforcement structure. Background Technology
[0002] In non-metallic underground mining operations, tunnel support is a crucial link in ensuring safe mine production, and its technological development has always been closely related to the characteristics of the ore and rock and the mining requirements. Currently, the ore and rock encountered in non-metallic underground mining often have significant characteristics such as low hardness, well-developed joints and fissures, and softening upon contact with water. This places stringent requirements on the adaptability, integrity, and reliability of the support structure. However, existing support technologies have revealed many structural defects in practical applications, especially in the overall design of the support system, where there are significant deficiencies.
[0003] According to patent document CN218894664U, a mine roadway support structure is disclosed, relating to the field of roadway support technology. This utility model discloses a mine roadway support structure, including a base. The top of the base is equipped with a support mechanism for supporting and protecting the mine roadway, and the bottom of the base is fixedly equipped with casters. This utility model uses a knob to drive a threaded rod to rotate. The threaded rod engages with a threaded sleeve, causing the threaded sleeve, a movable plate, and a limiting rod to move vertically, allowing the anchor bolt to be inserted into the roadway surface, thus fixing the support device. The movable plate contacts the roadway surface. Further rotation of the knob and threaded rod raises the support mechanism, facilitating support and protection for roadways at different heights. The top surface of a first support plate contacts the top surface of the roadway, and the second and first support plates provide double-layer protection, improving safety.
[0004] Existing support structures are generally only arranged at single points on the inner wall of the roadway, such as simply using U-shaped steel supports, fixing the support unit independently to the roadway rock wall. There is a lack of effective mechanical connection mechanism between adjacent support structures. This "island-like" support method results in the entire support system exhibiting discrete characteristics. When a single support is subjected to a large axial load caused by the deformation of the ore and rock, it is very easy to cause local damage due to the lack of coordinated force support from adjacent structures. More seriously, this local damage will produce a chain reaction. Other supports connected to the damaged support will be gradually stretched and deformed due to the lack of rigid connection, which will lead to the continuous failure of the support system. To address this, we propose a non-metallic underground mine support construction reinforcement structure. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a non-metallic underground mine support construction and reinforcement structure with the advantage of good support effect. It solves the problem that existing support structures generally only involve single-point arrangement on the inner wall of the roadway, such as simply using U-shaped steel supports, and fixing the support unit independently to the roadway rock wall. There is no effective mechanical connection mechanism between adjacent support structures. This "island-like" support method leads to the entire support system exhibiting discrete characteristics. When a single support is subjected to a large axial load caused by the deformation of the ore and rock, it is very easy to cause local damage due to the lack of cooperative force support from adjacent structures. More seriously, this local damage will produce a chain reaction. Other supports connected to the damaged support will be gradually stretched and deformed due to the lack of rigid connection, thus causing the continuous failure of the support system.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a non-metallic underground mine support construction and reinforcement structure, comprising a side support plate, a top support plate provided on the top of the side support plate, a first anchor rod inserted into the inner cavity of the side support plate, a second anchor rod inserted into the inner cavity of the top support plate, a housing fixedly connected to one side of the side support plate, a lead screw movably connected to one side of the top of the housing, a threaded sleeve threadedly connected to the surface of the lead screw, an adjusting frame fixedly connected to one side of the threaded sleeve, and a fixed connection to one side of the adjusting frame.
