MINE TUNNEL REINFORCEMENT GEOGRID
The mining geogrid produced by MTTVS® has raised mining innovation to a new level. This is an advanced high-strength polymer biaxial geogrid series, which is the best substitute for traditional steel/metal mesh, and is suitable for soft Underground mining of rock and hard rock. There are geogrids produced from two raw materials: polyester and polypropylene, each of which has unique characteristics and uses. One is ideal for the roof of mine tunnels, while the other is tailor-made for mine ribs/walls. MTTVS® mining geogrid has excellent performance and safety advantages and can be customized. It can be produced according to specific roll length, width and mesh aperture/opening size to achieve the best effect of its structure.
TYPES:
Mine geogrid roof
● The elongation is low, the actual data is 4.1%.
● It weighs about 0.9-1.3 kg per square meter, which is only 1/3 of the weight of the metal protective net. The size can be freely cut to facilitate on-site management.
● Good flexibility, reduces labor intensity of workers, and can effectively improve work efficiency
● Advanced flame retardant properties and antistatic coating (FRAS).
● Corrosion resistant, chemically and biologically inert.
● The breaking force of a single mesh belt of 8 steel wires>4000N
● It can provide ultra-high tensile strength up to 1000X1000 kN/m.
● The length, width and nominal aperture size of 25mm-100mm can be customized without affecting the structural integrity
● Used on the roof of mine tunnels.
Mine geogrid Rib
● Friction is not easy to generate static electricity. In the coal mine environment, the average surface resistance of the plastic mesh is 1×109Ω the following.
● Good flame retardant performance. In an open flame environment, it only melts but does not burn, even if it burns within 10 seconds from the fire, it will be extinguished.
● Easy to wash coal. The density of the plastic net is around 0.92. Less than the density of water, during the coal washing process, the broken mesh floats on the water surface and is easy to be washed away.
● It is convenient for construction and transportation.
● Corrosion resistance, anti-aging, chemically and biologically inert.
● Both vertical and horizontal directions have strong bearing capacity. The ribs and ribs formed by two-way stretching are perpendicular to each other. This structure enables the pressure applied to the mesh surface to be effectively transmitted to the surrounding ribs through the nodes, which improves the overall pressure-bearing capacity of the mesh surface. When an external force is applied to a certain rib (or rib), the external force is evenly distributed to other ribs (or ribs), which reduces the concentrated bearing capacity of a single root, so it is not easy to cause the ribs to break. The mesh creep is small and the mesh size is uniform, which can effectively prevent the falling of the broken coal and protect the safe operation of workers and mine carts.
● The length, width and nominal aperture size can be customized without affecting the structural integrity.
● It is used for the ribs of mine tunnels, and can also be used as a supporting material for various roadways such as bolting roadways, supporting roadways, and bolting and shotcreting roadways. When used for mine roof, it must be used together with two or more layers.
BENEFITS:
● Safety
● Light weight
● Antistatic
● Flame retardant
● Environmental friendly
● Repeated use
● Easy to install
● Life extension
● Corrosion resistance
● Save costs
