Geogrid for mining is a specialized geosynthetic material used in mining operations to reinforce and stabilize structures of the mining process. It is typically made from high-strength polymers (polyester or polypropylene) in grid structure with uniform apertures.
In mining applications, Geogrid is primarily used for two main purposes:
Reinforcement: Geogrid is employed to enhance the stability of mining structures and foundations, such as haul roads, access ramps, and tailings dams. When incorporated into these structures, the geogrid interlocks with the surrounding soil or aggregates, providing increased tensile strength and load-bearing capacity. This reinforcement prevents excessive deformation, rutting, and settlement, especially under the heavy loads and harsh conditions often encountered in mining environments.
Slope Stabilization: Geogrids are also used to stabilize slopes and prevent slope failures in mining operations. When installed on the surface of unstable slopes or as part of a reinforced soil slope system, the geogrid helps to retain the soil and rock in place, reducing the risk of landslides and rockfalls. This is crucial for ensuring the safety of mining personnel and equipment while optimizing the extraction process.
Geogrid for mining is engineered to withstand the harsh conditions found in mining environments, including exposure to aggressive chemicals, high pressures, and temperature variations. The material's resistance to corrosion and biological degradation ensures its long-term effectiveness and durability in these demanding settings.
Characteristics:
1) High-strength: The tensile strength is higher than that of the diamond mesh, and it can replace the diamond mesh.
2) Innovation: Weave the high-strength material by the plastic and the mesh joint is firm.
3) Low extension: Low unit extension, average stress, and avoid the appearance of the tuck net effectively.
4) Light: Weigh about 1kg/m2. Reduce the labor intensity, improve the working efficiency, and simple to install and use.
5) Safety: Static resistant, inflaming retarding, avoid the appearance of the electric sparkle effectively.
6) Erosion resistance: Its plastic surface ensures long service life and no invalidation caused by the erosion.
