These models of steel mesh each have their own characteristics and application scenarios. The following is a brief introduction to these steel meshes:
1. Diamond network
Structural features: The diamond shaped mesh is made of flat spiral mesh wires processed from hot-dip galvanized low-carbon steel wires, which are wound together one by one, and the mesh holes are in a diamond shape. This design gives the diamond mesh good breathability and a certain degree of elasticity, which can adapt to the movement of rocks or coal seams and reduce damage caused by pressure changes.
Application field: mainly used for artificial false roof, local roof protection of single coal seam fractured roof, working face closure, and roadway support during stratified mining of thick and extra thick coal seams in coal mines. The use of diamond mesh can effectively prevent roof collapse and coal seam collapse, and improve the safety of mines.
2. W-shaped steel strip
High strength characteristics: W-shaped steel strips are made of high-strength alloy plates by cold pressing, which have higher steel properties and strength. The flexural section modulus is 54 times higher than that of ordinary steel strips, and the hardening effect during cold pressing can increase the tensile strength by 28-46%.
Application effect: W-shaped steel strip is mainly used for roadway support in underground mine working faces, chambers, and other fields, especially suitable for handling unstable surrounding rocks. The application of W-shaped steel strip can significantly improve the overall effect of anchor rod support, especially in incomplete roof rock.
The above are the main models and characteristics of the steel mesh used in mines produced by our company. The design and application of each model are tailored to different needs in mine operations, such as providing additional support, enhancing work safety, or being suitable for specific geological conditions. These products play an indispensable role in ensuring mine safety production. When selecting a suitable steel mesh model, the specific conditions of the mine, such as geological characteristics and required support strength, should be comprehensively considered to ensure the optimal support effect.
