Product Description

Introduction of Coal Mine Underground Mining Biaxial tension Plastic Mesh

Underground coal mine plastic protecting mesh for is a kind of "double resistance" plastic mesh, have national MA certification.

Our protecting mesh is convenient for construction, lower cost, safe and beautiful.

The main features are not easy to generate static electricity due to friction, good flame retardant performance, strong anti-corrosion ability, easy to construct and transport, it is convenient to wash coal, and strong bearing capacity in both vertical and horizontal directions.

Product features of Coal Mine Underground Mining Biaxial tension Plastic Mesh

The product is made of polypropylene as the main raw material. After flame retardant and anti static treatment, it adopts biaxial tensile method to form a square grid with overall structure.

1. Due to Friction, our plastic mesh is not easy to produce static electricity. In the coal mine environment, the average surface resistance of plastic mesh is less than 1 * 109 Ω.

2. The flame retardant is good. In the open fire environment, it only melts but does not burn,Even if it burns, it will extinguish within 10 seconds from the fire.

3. Easy to wash coal. The density of the plastic mesh is about 0.92, which is less than that of water. In the process of coal washing, the broken mesh floats on the water surface and is easy to be washed off.

4. Strong corrosion resistance and anti-aging.

5. Convenient for construction and transportation. The plastic mesh is relatively soft, so it is not suitable to scratch workers in construction, and it has the advantages of easy curling, binding, cutting and light weight, so it is convenient for underground transportation, carrying and construction;

6. Our Plastic mesh have strong bearing capacity in both vertical and horizontal directions.

After extrusion and stretching, the molecular structure of the plastic mesh is reoriented, and the tensile strength of the material is 2-3 times of that before stretching.

The reinforcement and rib formed by biaxial tension are mutual perpendicular, which makes the pressure applied on the mesh surface can be effectively transferred to the surrounding ribs through the nodes, thus greatly improving the overall bearing capacity of the mesh surface.
When the external force is applied to a certain reinforcement (or rib), the external force is also evenly distributed to other reinforcement (or rib), which reduces the concentrated bearing capacity of a single reinforcement, so it is not easy to cause the fracture of the ribs.

Because the plastic mesh is biaxially stretched rather than woven, the creep of the mesh is small, and the mesh size is uniform, which can effectively prevent the falling of coal fragments and protect the safety of underground workers and the operation of the tramcar.
Application:
Our plastic mesh could for protecting the side wall for underground coal mine, also could as the supporting material for anchor bolt tunnel, supporting roadway, bolt shotcreting roadway and other roadways.
When it is use for roof, it must be combined with two or more layers.
