High-Strength UV Resistant Polyester Geotextile with Excellent Puncture Resistance for Mine Tailings Dam
Product Description
High-Strength Polyester Geotextile for Mine Tailings Dam
Our High-Strength Polyester Geotextile is a specialized geosynthetic material engineered specifically for reinforcement and filtration applications in mine tailings dams. Manufactured from 100% high-purity polyester fibers using advanced needle-punching or weaving technology, this product delivers uniform structure and consistent performance under demanding mining conditions.
Custom Specifications: Available in weights ranging from 100g/m² to 800g/m², with custom width and length dimensions tailored to your specific tailings dam requirements.
Key Performance Features
Reinforcement Capability
Tensile strength ≥80kN/m with 20-30% elongation at break
Effectively disperses tailings pressure on dam structures
Enhances overall dam stability and prevents deformation
Filtration & Drainage
Uniform pore structure (0.1-0.5mm) for optimal water flow
Retains soil particles and tailings solids while allowing seepage
Prevents drainage system clogging and reduces saturation risks
Chemical Resistance
Withstands long-term exposure to cyanide, sulfide, and heavy metal ions
Maintains performance integrity in harsh chemical environments
No degradation from mineral processing chemicals
Durability & Longevity
Service life exceeding 50 years in natural environments
UV-stabilized and anti-aging properties
Consistent performance throughout product lifecycle
Application Scenarios
This geotextile is specifically designed for mine tailings management applications including:
New tailings dam construction and reinforcement
Existing dam safety upgrades and renovations
Tailings disposal site filtration layers
Reinforcement of tailings pond auxiliary structures (drainage ditches, anti-seepage trenches, dam slope protection)
Filtration and reinforcement for coal gangue piles and waste rock yards
Large-scale metal mining operations (copper, gold, iron mines) requiring high safety standards
Installation & Usage Guidelines
Important Installation Requirements:
Ensure dam base surface is flat and free of sharp objects (stones, steel bars, glass)
Level uneven areas with sand or gravel before installation
Overlap adjacent geotextile edges by 15-20cm
Secure with specialized geotextile nails or seaming machines
Avoid dragging or rough handling during construction
Conduct comprehensive post-installation inspection for gaps, tears, or loose fixes
Perform regular monitoring of key areas (dam crest, slope foot)
Clean surface debris to maintain optimal drainage performance
