Feature

- high tensile, shockproof, water proof, uninflammable, anti-static, hot and cold resistant, acid and alkali-resistant, and structure-stability. It is not water swellable fabric.

-It is characterized by its fire resistant, oleic acid proof.

- We have made different thickness, diameter and length mining ducts according to the rigidity of the rock and coal seam.

- Less cost of will be needed for   the initial investment of mining duct. It can be used several times. With its high performance cost ratio, the total cost will be lower.

Application
