Steel-plastic composite false roof net for coal mine underground refers to a mesh product made of carbon spring steel wire wrapped with polyvinyl chloride resin and surface-treated. Its high strength and stable performance enable it to ensure its anchoring strength in various environments.
The steel-plastic composite false roof net used in coal mines is suitable for layered mining of thick coal seams and extra-thick coal seams in coal mines. It can also be used as a roof protection for the broken roof of a single coal seam to prevent goaf gangue and roadway support. It can also be used for supporting and anchoring projects such as tunnels, highway slope protection, seismic reinforcement of buildings, foundation and component anchoring, etc. The good corrosion resistance of plastic and the high strength formed by coating the steel wire can ensure its support strength in various environments, and it is easy to operate and use. It is an ideal product to replace the diamond-shaped metal false roof net
Steel-plastic composite false roof mesh, rhombus metal mesh, latitude and longitude mesh, resin anchors and anchoring agents, and emulsified oil for hydraulic supports (columns) used in underground coal mines.
Our group has been engaged in coal mine support products for several years and has won high praise from customers. Our company strives for survival by quality and development by innovation. We have patented products and use steel-plastic composite false roof nets underground in coal mines, which greatly improves safety. Coefficient or above (higher than the rhombus metal mesh, it is the best mesh for coal mine support.
Product performance characteristics
The elongation of low-elongation products is small. The measured data is , which effectively avoids the occurrence of problems in actual use. The phenomenon of net bags.
, The appearance of corrosion-resistant products is made of corrosion-resistant modified plastic. It will not rust or fail due to corrosion after long-term use, ensuring long-term protection.
, Light-weight products weigh per square meter Approximately 50 pounds, only about the size of a metal protective net of the same specification. The size can be cut freely, which is convenient for unit procurement management and warehousing, as well as job site management. The product has good flexibility, reduces the labor intensity of workers, and can effectively improve the operation Efficiency.
, The breaking force of a single mesh belt of high-strength steel wire reaches or exceeds the strength of the same type of metal mesh.
, Advanced safety and double resistance (antistatic performance, flame retardant performance) technical indicators , Improve the safety of underground use.
, The price is lower than the same type of metal mesh, which can effectively reduce the cost of mine support.
, Other modified outer covering plastic layers have affinity with concrete Stronger, it can improve the support strength of shotcrete tunnels, has strong shear resistance, effectively overcomes the limitations of all-plastic mesh in actual use, and has a wide range of applications.
Product use
This product is mainly used for It can also be used as a false roof and protective roof for layered mining of thick coal seams in underground coal mines. It can also be used as support materials for various tunnels such as anchor tunnels, support tunnels, and anchor blasting tunnels. It can also be used for other mine tunnel projects and slope protection. Anchoring and reinforcing materials for engineering, underground civil engineering and traffic road projects, it is the best alternative to plastic textile mesh and steel wire mesh.
