Mining Roof Support Geogrid  Introduction

Geogrid reforcing embankment of road/car park/railway/airport  belong to geosynthetics materials that fulfil a reinforcing function in a ground structure. They are formed by a flat polymer structure, namely by a system of mutually perpendicular longitudinal and cross drawn elements which can be bonded continually by weaving, welding, gluing or binding in the points of intersection thus usually creating apertures with sizes between 1 and 10 cm.

This allows penetration of particles of soil/rock or other geotechnical materials through mesh apertures and formation of particle interlocking. It is good for this reinforcing particle interlocking effect when the grains are able to push through the mesh with at least a half of their volume into the substrate layer.

  Mining Roof Support Geogrid are used both for reinforcement of non-cohesive, cohesive soils and formation made of coarse-grained materials.
Mining Roof Support Geogrid   are classified as uniaxial and biaxial grids
Uniaxial grid - strength in the machine direction of reinforcement is predominant
Biaxial grid - strengths in the cross and machine directions of the geogrid are equal

 

Mining Roof Support Geogrid  Application:

 

1.Base courses for road, railway, and airport construction

2.Construction of access roads and transportation links

3.Retaining structures and very steep banks

4.Slope stabilization

5.Noise-protection embankments

6.Contaminated land reclamation

7.Piled embankments

8.Landfill construction

9.Bridging of hollows and sink holes
