-made of strong biaxial polyester. Using double skin coated craft to stick the PVC fabric with high temperature.
-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.
1, With its strong impact resistance, it is indefectible. Accordingly ensure the perfect ventilation of the digging works, avoid of firedamp accumulation. It plays an important role in ventilation and safety in coal mines.
2, The length of each 5m mining duct after folding is only 0.25m, it is convenient for extending and effectively combine with footage driving cycle.
3, Each single duct is connected by spigot joint, it is very convenient for on-site installation and construction.
4,To make sure the safety of the site, we have made different thickness, diameter and length mining ducts according to the rigidity of the rock and coal seam.
5,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
Our tunnel and mining duct is suitable for high power strong ventilation fan which has been used in digging and coal mines with high gas content. In order to improve the ventilation facilities and ensure the safety of production. It is one of the most effective measurements to reduce manufacturing cost and enhance work efficiency.
