Mine Engineering Protective Gabion Mesh

Mining Engineering Special Protective Gabion Mesh - Mine Area Isolation / Slope Rockfall Protection / Tunnel Support - High-Strength Impact Resistance - Mine Safety Protection Net

II. Product Overview:

This mining engineering protective gabion mesh is specifically designed for high-risk scenarios such as mine area isolation, slope rockfall prevention, tunnel support, and tailings pond enclosures. Woven from high-toughness alloy steel wire, it features impact resistance, rockfall prevention, wear resistance, and corrosion resistance. It effectively reduces the risk of safety accidents in mining operations, complies with the "Safety Regulations for Metal and Nonmetal Mines" protection standards, and is suitable for various mining environments including open-pit mines, underground mines, and quarries.

III. Core Advantages:

Tailored for the extreme conditions of mining environments (vibrations, heavy impact, dust and rain erosion, complex terrain), highlighting fundamental differences from ordinary protective nets:

1. Blast and Impact Resistance, Withstands Strong External Forces in Mines

• Material and Strength: Uses 65Mn spring steel wire (high toughness) or Q355 high-strength low-alloy steel wire, wire diameter 4.0-8.0mm (customizable), tensile strength ≥800MPa, elongation at break ≥15%. Capable of withstanding shock waves (≤0.5MPa) and rockfall impacts (single rock weight ≤500kg). The mesh resists breaking upon impact, only deforming slightly (deformation ≤10%), avoiding immediate failure upon collision.
• Weaving Process: Employs a "triple-twist encrypted gabion" technique, with diamond-shaped mesh openings (common sizes: 8cm×12cm, 10cm×15cm). The mesh is tightly interwoven with uniform tension, dispersing impact forces (e.g., shock waves, slope rockfall impacts) through elasticity, improving impact resistance by over 40% compared to ordinary welded mesh.

2. Wear and Corrosion Resistance, Adapts to Harsh Mining Environments

• Surface Treatment: Provides dual protection with "hot-dip galvanizing + plastic coating" (core process). Zinc layer thickness ≥120μm (hot-dip galvanizing), plastic coating thickness ≥0.8mm (using outdoor-specific weather-resistant powder). Salt spray test resistance ≥1000 hours, wear resistance test (sand abrasion method) ≥500 cycles without exposure of base material. Resists corrosion from mine dust (including acidic substances), rainwater immersion, and damp conditions in underground tunnels. Service life up to 10-20 years (8-15 years in open-pit mines, 15-20 years in underground mines), reducing downtime costs from frequent replacements.
• Edge Reinforcement: Mesh edges feature a "steel rope border + flange fixation" design, with edge wire diameter thickened to 10mm. Welded joints with the mesh are fully welded to prevent edge fraying from rock abrasion or dragging, enhancing overall durability.

3. Multi-Scenario Adaptability, Covers Full Mining Process Protection

• Applicable Areas and Functions:
  • Open-Pit Mine Isolation: Installed within a 30-50 meter operational radius as a "buffer protection layer" to block flying debris (diameter ≤30cm), preventing injury to personnel or equipment, while clearly marking restricted zones in compliance with mine safety distance regulations.
  • Slope / Waste Dump Rockfall Protection: Deployed on mine slopes (gradient ≤60°) or waste dump edges. Mesh size customizable (small mesh for debris, large mesh for bigger rocks), fixed with anchor bolts (≥4 fixation points per square meter) to form a "flexible protection layer" that blocks rolling rocks, preventing landslides or rockfalls from damaging roads and equipment below.
  • Underground Mine Tunnel Support: Used for temporary support of tunnel roofs or sidewalls (replacing some steel supports). The mesh elasticity buffers surrounding rock pressure, prevents small rock fragments from falling, and allows ventilation. Weighs only 1/3 of traditional steel supports, reducing installation load.
  • Tailings Pond / Stockyard Enclosure: Encloses tailings accumulation areas or ore storage yards to prevent leakage or loss. The mesh has high permeability (80% water permeability), avoids water accumulation, and reduces collapse risks from rainwater erosion.
• Specification Flexibility: Mesh width 1.5-5m, length customizable (standard 20m/roll). Can bend to fit mine terrain (slopes, corners, curves) with ≥90% conformity, suitable for uneven areas.

4. Compliance and Safety, Meets Mine Acceptance Standards

• Complies with the "Safety Regulations for Metal and Nonmetal Mines" (GB16423-2020) requirements for protective mesh strength and corrosion resistance. Provides third-party test reports (including tensile strength, impact resistance, corrosion resistance), ensuring passage of mine safety inspections and avoiding shutdowns due to non-compliant protection.

IV. Technical Parameters:
