Mine geogrid may be a quite plastic protective mesh utilized in the underground coalpit, which takes polypropylene because the main staple, after being treated with flame retardant and antistatic technology, and adopts the tactic of bidirectional tension to make the entire structure of “double anti-resistance” plastic mesh. This product is convenient for construction, low cost, safe and delightful. Mine geogrid within the coalpit work is additionally called the coalpit underground with two-way tensile plastic mesh false roof, mentioned as a false roof net. high quality biaxial geogrid is specially designed and made for false roof support and roadway protection and support of underground mining working face, which is formed by heating, extrusion, forming, punching, drawing, shaping, coiling and other processes with several sorts of polymer and other modifiers. Compared with metal textile mesh and plastic woven mesh, the uniaxial plastic geogrid price has the characteristics of sunshine weight, great strength, isotropy, anti-static, non-corrosion, and flame retarding. The mine geogrid is especially utilized in the false roof support engineering of underground mining face, the mine geogrid also can be used because the earth and stone anchoring and strengthening material for other mine roadway engineering, slope protection engineering, underground engineering, and traffic road engineering, the mine geogrid is one among the simplest substitute products of the plastic textile net.
