 Our PVC tunnel and mining duct is made of strong biaxial polyester. Using double skin coated craft to stick the PVC fabric with high temperature. It is characterized by 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.
-
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.
-
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.
-
Each single duct is connected by spigot joint, it is very convenient for on-site installation and construction.
-
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.
-
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.
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.
Notes: The most popular underground ventilation products of Dafeng is: Suspension type ventilation duct which has been widely used for positive pressure ventilation for the coal mines and tunnel worldwide.
Detailed description：
Dafeng has specialized in manufacturing ducts for worldwide mining and tunnel industry since 1998. We are the leading supplier of Australia、South Africa mining companies, as well as the leading company aiming at the development and design of plastic coating products for worldwide underground ventilation duct market.
 Customers from mining and tunnel industry are asking for durability, intensity and quality. The high intensity production lines and patented mining ducts of Dafeng have been tested and verified by customers from worldwide for many years. With our updated product design and experience on mining and tunnel industry, Dafeng’s flexible ventilation products are characterized by high tear strength and tensile strength, good barotolerance. It can reduce pressure loss and leakage. The features of fire-resistant, antistatic,UV resistance,resistance of cold and convenience of our products are tested and verified by authority groups. It allows remote distance operation from the ventilation fans to the ventilated areas.
