The steel plastic composite protective net used in coal mine is a kind of steel plastic composite false roof belt which is made of polyethylene (PE) and steel wire as the main raw materials, after flame retardant and antistatic technology treatment, plasticized extrusion and steel wire reinforced materials are combined into a steel plastic composite false roof belt, which is bonded and welded into an integral grid structure according to a certain welding distance.

Product features: 1, friction is not easy to produce static electricity. In the coal mine environment, the average surface resistance of plastic coated steel wire is less than 1 × 109 Ω.

2. It has good flame retardancy.

3. Good corrosion resistance and rust resistance. The appearance of the product is corrosion-resistant modified plastic, which will not rust and lose efficacy due to corrosion for a long time to ensure the long-term protection effect.

4. It is convenient for construction. Because the steel wire is covered with a layer of soft plastic layer, it is not easy to scratch workers in the process of construction and transportation. At the same time, the steel wire is easy to shear, and there is no need to remove the mesh when mining, which reduces the labor intensity of workers and greatly improves the work efficiency.

5. Strong bearing capacity. The mesh belt has small elongation and uniform force, which can effectively avoid mesh pocket and has high strength. The plastic coating has stronger affinity with concrete, which can improve the support strength of shotcrete roadway.

Scope of application: the product is suitable for supporting and supporting in thick coal seam and extra thick coal seam to prevent gangue channeling in goaf and roadway support; it can also be used for slope protection of tunnels and expressways, seismic reinforcement of buildings, anchoring of foundation and components, etc. The steel plastic composite side net used in coal mine is another innovative product after glass bolt.
