Information

Geogrid used in mining is a kind of plastic fence used in coal mine, which is made of polypropylene as the main raw material and treated by flame retardant and anti-static technology. It is a "double anti" plastic net with overall structure formed by two-way stretching method. The product is convenient for construction, low cost, safe and beautiful.

Geogrid used in mining work is also known as the two-way tensile plastic net false roof, referred to as the false roof net. The mining geogrid is specially designed and manufactured for the false roof support and roadway support of the underground mining working face of the coal mine. It is made of several kinds of high polymer and other modifiers after heating, extrusion, forming, punching, stretching, shaping, coiling and other processes. Compared with metal textile net and plastic woven net, Geogrid used in mining has the characteristics of light weight, high strength, isotropy, antistatic, corrosion-free and flame-retardant. It is a new type of grid material for underground support engineering and civil engineering.

Geogrid used in mining is mainly used for the false roof support engineering of the underground mining working face of the coal mine. Geogrid used in mining can also be used as the earth rock anchoring and strengthening materials for other mine roadway engineering, slope protection engineering, underground civil engineering and traffic road engineering. Geogrid used in mining is one of the alternative products of the plastic textile network.

Geogrid used in mining technical advantages

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

Good flame retardancy. Geogrid used in mining can meet the requirements of coal industry standards MT141-2005 and mt113-1995 respectively.

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

Geogrid used in mining corrosion resistance is strong, anti-aging.

Geogrid used in mining convenient for construction and transportation. The plastic net is relatively soft, so it is not suitable for workers to be scratched in construction, and it is easy to curl and bind, the mining grid is cut and the proportion is light, so it is convenient for underground transportation, carrying and construction.

Geogrid used in mining has a strong bearing capacity in both vertical and horizontal directions. Because the plastic mesh is biaxially stretched rather than woven, the mesh creep is small, and the mesh size is uniform, which can effectively prevent the falling of coal fragments, protect the safety of underground workers and the safety of underground workers and the operation of mining cars.

Geogrid used in mining application area

Geogrid is mainly used for the support of underground mining, and can be used as the support materials of bolt roadway, support roadway, bolt and shotcrete roadway and other roadways. When it is used for false roof, it is used in combination with more than two layers.
