PP mesh for Coal Mine

Introduction:

Mining Grids are especially for underground mine and tunnel applications.

The grids have an integrally formed structure with high tensile strength on MD and TD directions.

Mining Grids are manufactured from special formula with flame-retardant polymer.  

Performance:

Demensions:

Application:

1. It can be applied in all kinds of roads, railways, airports to enhance the roadbed. 

2. It can be applied in a large car park and terminal freight yard, etc. to strengthen the foundations of a permanent load; 

3. It can be applied in rail, road slope’s protection; 

4. It can be applied to enhance the culvert; 

5. It can be applied as a secondary enhancement after the uniaxial geogrid soil enhancement, further enhancement to the

soil; prevent soil erosion; 

6. It can be applied in mining, tunnel reinforcement.
