Mine grille is a kind of plastic protective net for underground coal mine. Polypropylene is used as the main raw material. After being treated by flame retardant and antistatic technology, the whole structure of "double resistance" plastic net is formed by biaxial stretching method. The product is easy to construct, low cost, safe and beautiful.
Mine geogrid in coal mine work is also called biaxial tension plastic net false roof, referred to as false roof net. Mine geogrid is specially designed and manufactured for false roof support and roadway support in www.penwuganzaojii.cnwww.gangchensu.cnwww.chenban.net.cnwww.taocichenban.cnunderground www.zhutiezhamen.net.cnwww.buxiugangwanguan.cnmining face. It is manufactured by heating, extrusion, forming, punching, stretching, finalizing and coiling with several kinds of polymer and other modifiers. Compared with metal textile mesh and plastic woven mesh, mine geogrid has the characteristics of light weight, high strength, isotropy, antistatic, non-corrosive and flame retardant. It is a new type of mesh material for underground support engineering and civil engineering in coal mine.
Mine geogrid is mainly used for false roof support engineering in underground mining face of coal mine. Mine geogrid can also be used as earth-rock anchorage and reinforcement material in other mine roadway engineering, slope protection engineering, underground civil engineering and traffic road engineering. Mine geogrid is one of the best substitutes for plastic textile network.
