Description

Technical Field

[0001] This utility model relates to the field of mine roadway support technology, and in particular to an adjustable anchor bolt bracket for supporting large-section roadway intersections. Background Technology

[0002] Adjustable anchor bolt supports for large-section roadway intersections are mainly used for support operations at large-section roadway intersections to improve the stability of the area and ensure the safe operation of mining.

[0003] During mining operations, large-section roadway intersections face numerous support challenges due to their unique spatial structure and stress characteristics. Existing support methods and supports have the following shortcomings: 1. Poor adaptability: Traditional anchor bolt supports are mostly fixed structures, and their size and angle are difficult to adjust flexibly according to the actual shape, span, and surrounding rock conditions of large-section roadway intersections. The parameters of roadway intersections vary greatly in different mining areas or at different locations in the same mining area. Fixed-structure supports cannot meet diverse support needs, resulting in poor support effects. 2. Insufficient support strength: The ground stress at the intersection of large-section roadways is complex and concentrated. The strength design of traditional supports often cannot fully consider this complex stress situation. Under high stress, they are prone to deformation and damage, and cannot provide durable and reliable support for the roadway intersection, increasing the risk of roadway collapse. 3. Inconvenient installation: Some support structures are complex with numerous parts. In the limited space and complex environment underground, installation and disassembly are difficult, consuming a lot of manpower and time, affecting construction efficiency, and the installation quality is difficult to guarantee, thus affecting the support effect. 4. Uneven stress distribution: Traditional supports cannot fit well with the surrounding rock of the roadway during the support process, resulting in stress concentration in local areas, while other areas are not adequately supported. This accelerates the deformation and damage of the surrounding rock of the roadway and reduces the overall stability of the support structure. Utility Model Content
