Description

Technical Field

[0001] This utility model relates to the field of fault support structure technology, and in particular to a fault support structure for the mining of rock gold mines. Background Technology

[0002] In the mining of gold mines, complex geological conditions such as fault fracture zones are key challenges affecting construction safety and efficiency. Fault areas have well-developed rock fissures and poor self-stability, making them prone to geological disasters such as roof falls and spalling under blasting disturbances or in-situ stress, seriously threatening worker safety and causing downtime losses. While traditional support methods (such as anchor-mesh shotcrete support and steel frame support) can provide basic support, they have the following prominent technical problems: Existing support structures mostly use integral welding or rigid connections. When local metal mesh is damaged due to rock compression, corrosion, or puncture by sharp objects, the entire structure must be dismantled and large components replaced. For example, in a mine operating on the F5 fault zone, a single repair due to localized metal mesh tearing took 8 hours, resulting in 30% material waste and significantly increasing non-production downtime and material costs. Rock deformation in fault areas is discontinuous and sudden, making traditional rigid supports unable to adapt to the dynamic displacement of the surrounding rock. Actual test data from a mine showed that after blasting vibrations, the connection nodes of traditional support structures are prone to loosening with gaps of 10-15mm, resulting in a 40% decrease in the load-bearing capacity of the support system, making it unable to effectively resist the collapse winds caused by secondary stress release. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a fault support structure for gold mining, which more accurately solves the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a fault support structure for gold mining, including a metal mesh. A first fixing frame is provided on the surface of the metal mesh, and a second fixing frame is provided on the back of the metal mesh. The metal mesh is positioned between and detachably connected to the first and second fixing frames. The two first fixing frames are detachably connected to each other for replacing individual metal meshes when they are damaged. A first docking component and a second docking component are respectively installed on both sides of the first fixing frame. The first and second docking components are arranged in a circumferential array around the center of the first fixing frame. A docking hole is provided on the other first fixing frame relative to the positions of the first and second docking components for positioning after the first and second docking components are inserted.

[0006] Preferably, both the first and second docking components include a movable connecting plate, and a pin is installed at the bottom of the connecting plate. The pin is inserted into the docking hole at the corresponding position to limit the movement of the two support structures.

[0007] Preferably, a mounting plate is installed on the top of the first fixed frame, and a connecting spring is installed on the bottom of the mounting plate. The bottom of the connecting spring is connected to the connecting plate to push the connecting plate to the top of the first fixed frame and make contact with the first fixed frame.

[0008] Preferably, a guide rod is installed on the top of the connecting plate, the guide rod is connected through the mounting plate, and a pull plate is installed on the top of the guide rod for pulling the guide rod.

[0009] Preferably, threaded holes are provided at the metal mesh, the first fixing frame, and the second fixing frame. A bolt is provided at the top of the first fixing frame, and the bolt is threadedly connected to the metal mesh, the first fixing frame, and the second fixing frame through the threaded holes.

[0010] Preferably, the top of the fixing frame is provided with an internal groove at the threaded hole, and the internal groove is used for the bolt to be inserted into the threaded hole.

[0011] Compared with the prior art, this utility model provides a fault support structure for gold mining, which has the following advantages:

[0012] This gold mine utilizes a fault support structure. Through a modular assembly design, the support structure is connected to the metal mesh via detachable bolts in two fixed frames, and through a mating joint and hole-connecting structure between the fixed frames. When a section of the metal mesh is damaged, only the bolts of the corresponding module need to be removed for individual replacement, avoiding complete scrapping and significantly reducing material consumption and maintenance costs.

[0013] This gold mine utilizes a fault support structure, employing a dual safety protection system through a combination of spring-loaded preload inserts and embedded limiting structures with connecting holes, along with a mechanical locking mechanism for guide rods and pull plates. Under conditions of fluctuating rock pressure, the spring preload absorbs dynamic displacement, preventing loosening of the connection; the guide rod system ensures connection reliability under extreme conditions through mechanical interlocking.

[0018] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model. Example

[0019] like Figures 1-3 As shown in the figure, an embodiment of this utility model proposes a fault support structure for gold mining, including a metal mesh 1. A fixing frame 2 is provided on the surface of the metal mesh 1, and a fixing frame 3 is provided on the back of the metal mesh 1. The metal mesh 1 is clamped between the fixing frame 2 and the fixing frame 3, and is detachably connected by bolts 8 passing through threaded holes 7 on the fixing frame 2, the metal mesh 1, and the fixing frame 3. A connecting piece 4 and a connecting piece 5 are respectively installed on both sides of each fixing frame 2, arranged in a circumferential array around the center of the fixing frame 2. A connecting hole 6 is provided on another fixing frame 2 at a position corresponding to the connecting pieces 4 and 5. When two support structures need to be connected, the connecting pieces 4 and 5 are inserted into the corresponding connecting holes 6 to achieve positioning and connection. Through the above implementation, a modular design of the support structure is achieved. When the metal mesh 1 is damaged, it can be replaced individually without replacing the entire support structure, reducing maintenance costs. Meanwhile, the cooperation of connecting parts 4, 5, and 6 enables rapid connection and positioning between support structures, thus improving construction efficiency.

[0020] In this invention, both the first connecting member 4 and the second connecting member 5 include a movable connecting plate 51, and a pin 52 is installed at the bottom of the connecting plate 51. When the two support structures need to be connected, the pin 52 is inserted into the corresponding connecting hole 6. Through the tight fit between the pin 52 and the connecting hole 6, the two support structures are limited. Through the above-described embodiment, the fit between the pin 52 and the connecting hole 6 ensures the connection stability between the support structures, prevents the support structures from moving or separating relative to each other when under stress, and improves the safety and reliability of the support structures.

[0021] In this invention, a mounting plate 53 is installed on the top of the fixed frame 2, and a connecting spring 54 is installed on the bottom of the mounting plate 53. The bottom of the connecting spring 54 is connected to the connecting plate 51. Through the elastic force of the connecting spring 54, the connecting plate 51 is pushed to the top of the fixed frame 2 and contacts the fixed frame 2. In this way, when connecting two support structures, the insert 52 can be more easily inserted into the mating hole 6 and maintain a stable connection. Through the above embodiment, the connecting spring 54 provides a preload force to the connecting plate 51, so that the insert 52 can maintain a stable connection when inserted into the mating hole 6, thereby improving the connection strength and stability between the support structures.

[0022] In this invention, a guide rod 55 is installed on the top of the connecting plate 51, and the guide rod 55 is connected through the mounting plate 53. A pull plate 56 is installed on the top of the guide rod 55. When it is necessary to disassemble or adjust the support structure, the guide rod 55 and the connecting plate 51 can be moved upward by pulling the pull plate 56, thereby releasing the connection between the insert 52 and the docking hole 6. Through the above embodiment, the guide rod 55 and the pull plate 56 provide a convenient way to pull the connecting plate 51, so that the connection can be quickly and easily released when it is necessary to disassemble or adjust the support structure, thus improving construction efficiency and flexibility.

[0023] In this invention, threaded holes 7 are provided at the metal mesh 1, the first fixing frame 2, and the second fixing frame 3. During assembly of the support structure, bolts 8 are passed through the threaded holes 7 on the first fixing frame 2, the metal mesh 1, and the second fixing frame 3, and the bolts 8 are rotated to connect with the threaded holes 7, thereby achieving a detachable connection between the metal mesh 1, the first fixing frame 2, and the second fixing frame 3. Through the above implementation, the cooperation between the bolts 8 and the threaded holes 7 enables a detachable connection between the metal mesh 1, the first fixing frame 2, and the second fixing frame 3, allowing the metal mesh 1 to be replaced individually when damaged, thus reducing maintenance costs.

[0024] In this invention, the top of the fixing frame 2 has an internal groove 9 located at the threaded hole 7. When the bolt 8 is inserted into the threaded hole 7, the head of the bolt 8 can be placed inside the internal groove 9, preventing the bolt head from protruding from the surface of the fixing frame 2 and affecting the overall aesthetics and safety of the support structure. Through the above-described embodiment, the design of the internal groove 9 allows the bolt 8 to be placed inside the fixing frame 2 after installation, maintaining the overall aesthetics and safety of the support structure, while also facilitating subsequent inspection and maintenance.
