Mining geogrids 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.

Mining geogrid application scopes:

Longwall face recovery for roof support

On both ends of longwall face for roof support

Ultra-high drainage tunnel and old tunnel for roof support

Gangue blocking,buffering and protection of the declining longwall faces

Buffering and protection of the blast area

Slice mining longwall faces

Declining longwall faces for roof support

Mining geogrid characteristics:

Large square, flexible and light, strong tensile strength

Simple and convenient construction

Fire-resistant and antistatic

Avoid frequent mesh transportation and weaving

High safty and low labour

Flexible production with different strength and specifications
