However, it should be understood that these details on the actual object should not be used to limit the utility model. That is to say, in some embodiments of the utility model, these details on the actual object are unnecessary. In addition, for the purpose of simplifying the drawing, some conventional structures and components will be drawn in a simple schematic way in the drawing.

[0029] In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on that a person skilled in the art can realize, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the utility model.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 The purpose of mine roadway protection is to ensure the personal safety of miners during the working and passing process in the mine roadway. There are risks of geological disasters such as roof collapse, slope landslide and rock collapse in the mine roadway, and the roadway protection measures can reduce or avoid the harm of these disasters to the miners, based on this, the application provides a mine roadway supporting assembly, which comprises one or more support parts 1 for roadway supporting and a fastening part 2 arranged between the support parts 1, a spacing area 4 is arranged between the two support parts 1, and a reinforcing assembly 3 is installed at the spacing area 4 for supporting the inner wall of the roadway;

[0031] The support part 1 comprises a rod body 11, and one or more clamping grooves 12 are arranged on the outer side of the rod body 11 in a ring shape, and the clamping groove 12 is matched with the fastening part 2.

[0032] The fastening part 2 includes a screw rod 23, one end of which is tapered and fixed to the inner wall of the roadway, and the other end of which is fixed with a nut 22. The outer side of the screw rod 23 is further sleeved with a baffle 21, which is adapted to the clamping groove 12 of the rod body 11 of the support part 1, for fixing the support part 1.

[0033] The annular rod body 11 of the support part 1 can provide more uniform support force distribution, enhancing the support effect on the inner wall of the roadway. Secondly, the fastening part 2 adopts the structure of tapered screw rod 23 and nut 22, which is fixed by tightening the nut 22, so that it is closely combined with the inner wall of the roadway, improving the firmness and stability of the support. At the same time, the setting of the baffle 21 can ensure that the support part 1 is closely combined with the fastening part 2 during installation, preventing it from loosening or falling off.

[0034] In practical application, according to the specific situation and demand of the roadway, the interval area 4 between the support parts 1 and the position of the installation reinforcing assembly 3 can be flexibly adjusted to adapt to the shape and size of different roadways, realizing customized support and reinforcement effect. The design of this ore mining roadway support assembly optimizes the support structure of the roadway, provides a more effective and reliable roadway support scheme, which can reduce the risk of roadway collapse and collapse, thereby protecting the safety of miners and the normal operation of the mine.

[0035] Please refer to Figure 2 、 Figure 7 The reinforcing assembly 3 includes one or more reinforcing rods 32, which are cross-set at a preset angle between two reinforcing rods 32, and are fixed by a positioning pin 31 between the two reinforcing rods 32.

[0036] The two ends of the reinforcing rod 32 are respectively adapted to the rod body 11 of the two support parts 1, and form a "triangular" structure at the interval area 4, which fixes the two support parts 1.

[0037] The "triangular" structure makes the reinforcing rod 32 be able to provide more powerful resistance, enhancing the connection stability between the support parts 1. The reinforcing rod 32 cross-set at a preset angle can form a three-way support structure, effectively bearing the pressure of the inner wall of the roadway, preventing it from deforming or collapsing. Through the fixation of the positioning pin 31, the position and stability of the reinforcing rod 32 can be ensured, preventing it from loosening or shifting.

[0038] In practical application, according to the characteristics and demand of the roadway, appropriate number of reinforcing rods 32 can be selected to meet the requirements of roadway support. The "triangular" structure of the reinforcing assembly 3 can flexibly adapt to different roadway shapes and sizes, providing effective support and reinforcement effect.

[0039] By setting the reinforcing rods 32 at a preset angle and fixing them with the positioning pins 31, not only the stability between the support parts 1 is increased, but also the pressure from the inner wall of the roadway can be borne and transmitted to the support parts 1, further enhancing the strength of the entire support system.

[0040] The two ends of the reinforcing rods 32 are adapted to the annular rod body 11 of the support part 1, forming a triangular structure with high stability and resistance. Through the fixed resistance mode, it is ensured that the support part 1 can bear a larger force without deformation or damage. This design not only enhances the stability of the entire support structure, but also effectively disperses and slows down the stress of the inner wall of the roadway, reducing the risk of roadway collapse and collapse.

[0041] In addition, by selecting a preset angle and adjusting the number of reinforcing rods 32, the support and reinforcement effect can be optimized according to the specific roadway conditions and requirements. Such flexibility makes the support assembly suitable for various roadway specifications and shapes, meeting the mining needs under different geological conditions.

[0042] The support part 1 used above can be one of the common parts in the mechanical field, such as HRB400 threaded steel, I-beam (such as Figure 7 ) and the like;

[0043] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 , the middle part of the baffle 21 is provided with a positioning hole 25 adapted to the screw rod 23, which is used to force the baffle 21 to pass through the outside of the screw rod 23.

[0044] The bottom of the baffle 21 is provided with at least two symmetrically arranged clamping blocks 24, which are adapted to the clamping groove 12, for supporting the baffle 21.

[0045] The vertical distance of the spacing area 4 is adapted to the vertical distance and / or diagonal distance between the two clamping blocks 24.

[0046] The middle part of the baffle 21 is provided with a positioning hole 25 adapted to the screw rod 23, which is used to force the baffle 21 to pass through the outside of the screw rod 23, realizing the close combination of the baffle 21 and the screw rod 23. This design can enhance the stability and support of the baffle 21, ensuring its fixed position in the roadway.

[0047] Secondly, the bottom of the baffle 21 is provided with at least two symmetrically arranged clamping blocks 24, which are adapted to the clamping groove 12, for supporting the baffle 21. The design of the clamping block 24 enables it to be firmly inserted into the clamping groove 12, providing stable support force for the baffle 21. Through the close cooperation of the clamping block 24 and the clamping groove 12, the baffle 21 can effectively resist the pressure of the inner wall of the roadway and maintain its fixed position.

[0048] In addition, the vertical distance of the spacing region 4 is matched with the vertical and / or diagonal distance between the two clamping blocks 24. This matching ensures that the length of the spacing region 4 is consistent with the distance between the clamping blocks 24, so that the baffle 21 can closely fit the inner wall of the roadway and provide uniform support force distribution. By optimizing the size of the spacing region 4, appropriate support effect can be achieved, reducing the pressure on the roadway wall and reducing the risk of deformation or collapse.

[0049] At the bottom of the baffle 21, at least two clamping blocks 24 are symmetrically arranged. These clamping blocks 24 are matched with the clamping grooves 12 and are used to support the baffle 21. The design of the clamping blocks 24 allows them to be firmly inserted into the clamping grooves 12, providing uniform support force for the baffle 21. Through the close fit of the clamping blocks 24 and the clamping grooves 12, the support force is balanced and dispersed to the entire baffle 21, preventing the roadway wall from collapsing and providing stable support.

[0050] In addition, the vertical distance of the spacing region 4 is matched with the vertical and / or diagonal distance between the two clamping blocks 24. This matching ensures that the length of the spacing region 4 is consistent with the distance between the clamping blocks 24, so that the baffle 21 can closely fit the inner wall of the roadway and provide uniform support force distribution. By optimizing the size of the spacing region 4, appropriate support effect can be achieved, reducing the pressure on the roadway wall and reducing the risk of deformation or collapse.
