Hebei BAO’s Solid Woven PVG belts are specifically designed for demanding underground coal mining applications where safety and performance are equally critical. The carcass is formed from a dense, integral woven fabric saturated in PVC paste, which is then covered with a resilient Nitrile Rubber (NBR) and PVC blend layer. This dual-layer construction provides superior resistance to abrasion and tearing, higher gripping friction, and improved operational stability on inclines up to 20 degrees, all while maintaining strict anti-static and flame retardant standards.
Key Features
- High Surface Abrasion Resistance
- Superior Grip on Inclines
- Permanent Anti-Static Protection
- Certified Flame Retardancy
- High Impact and Tear Strength
- No Risk of Ply Delamination
Applications & Industries
Underground Coal Mining
Provides certified safety and reliability for high-volume, long-distance haulage.
Steep Incline Transport
Handles materials efficiently on slopes up to 20 degrees due to high friction cover.
Potentially Explosive Areas
Eliminates static build-up, preventing ignition in gas and dust-heavy zones.
Bulk Material Tunnels
A robust, low-maintenance solution for enclosed and high-risk subterranean projects.
As a specialized custom solution provider, Hebei Boao views these figures as performance benchmarks. We provide precision engineering, meaning the following parameters are fully negotiable and will be fine-tuned to your exact project needs: Belt Width, Cover Thickness (2.5mm to 4.5mm), Ply Count, Rubber Grade, and the required Safety Factor (Safety factor 10). Our final product is certified to meet your unique specifications, ensuring optimized performance and longevity.

FAQs
1. What is the key difference between PVG and PVC solid woven belts?
PVG belts feature an added rubber-based top and bottom cover, which significantly enhances abrasion resistance and grip compared to the PVC plastic covers.
2. What is the recommended maximum transporting angle?
The recommended transporting angle for our PVG belts is less than 20 degrees, which is higher than standard PVC belts.
3. How is the 10:1 safety factor calculated?
The safety factor of 10 means the tensile strength of the belt is ten times the maximum working tension (tensile strength * 1/10).
4. How do you ensure static electricity will not build up?
The belt is manufactured to maintain a low surface resistivity, with an average value less than 3.0 x 10^8 Ohms, preventing static accumulation.
5. Can the PVG belt handle high shock loading?
Yes, the integral solid woven carcass construction is specifically designed to handle high impact and shock loading without suffering ply separation.
6. What is the typical cover thickness for PVG belts?
Each cover (top and bottom) is typically between 1.5mm and 4.5mm thick, customized based on your abrasive environment.
