Products Description
Mining false roof mesh, also known as mining grid, is a type of plastic protective mesh used underground in coal mines.
It is mainly made of polypropylene as the main raw material, and after being treated with flame retardant and anti-static technology, it is formed by a bi-directional stretching method to form a "double anti" plastic mesh with an overall structure.

Products advantage
- Friction is less likely to generate static electricity. In the underground environment of coal mines, the average surface resistance of plastic mesh is 1 × Below 109 Ω.
- Good flame retardant performance. It can achieve the flame retardant performance specified in the coal industry standards MT141-2005 and MT113-1995, respectively.
- Strong corrosion resistance and aging resistance.
- Easy for underground transportation, carrying, and construction.
- Strong load-bearing capacity, and uniform mesh size, which can effectively prevent the falling of crushed coal blocks.

Products application
This product is mainly used as a false roof and support for thick coal seam stratified mining in coal mines.
It can also be used as a support material for various tunnels such as anchor bolt tunnels, support tunnels, anchor spray tunnels, etc.
It can also be used as an anchoring and strengthening material for other mining tunnel engineering, slope protection engineering, underground civil engineering, and traffic road engineering.
It is the best substitute product for plastic textile mesh and steel wire mesh.
