Introduction
Geogrid is knitted by polymer yarns with high strength, high modulus and low creep and coated with advanced technology. It is specially used as the substitute of metallic mesh for longwall face recovery and you do not need to weave the mesh frequently on site before the longwall stops.
Polyester mesh is going to be lift at the position 15-25 meters away from the stopping line with winches and fixed pulley at one time. Mesh laying, lifting and advance is circulated with the share pass. Mesh application affords the technical innovation meaning to improve the longwall face recovery efficiency and security.
polyester mesh is 3-6 m wide and 50-200 m long with tensile strength ranging from 100kn/m-800kn/m. Mesh with strength 800-1000kn/m for special projects can also be supplied. We will manufacture mesh based on the parameters of longwall faces.
Characteristics:
1.Large square, flexible and light, strong tensile strength
2.Simple and convenient construction
3.Fire-resistant and anti-static
4.Avoid frequent mesh transportation and weaving
5.High safty and low labour
6.Flexible production with different strength and specifications
