Mine-specific Protective Net

Mine-Special Protective Gabion Mesh - Blast/Impact Resistant / Rockfall Prevention / Wear-Resistant - Open-Pit Mine Slopes / Underground Tunnels / Material Yard Isolation Safety Net

II. Product Overview:

Mining environments (open-pit mines, underground tunnels, material yards) face multiple safety hazards such as blast rockfall, slope collapse, equipment collisions, personnel entering danger zones, and slag corrosion. This mine-specialized protective gabion mesh is designed to address these challenges. It is woven from high-strength, wear-resistant metal wire and can be customized based on mine type (open-pit / underground), protection scenario (slope / shaft entrance / equipment area), and hazard level (blast zone / regular operation area). It features "impact resistance, fall prevention, slag corrosion resistance, and adaptability to complex terrain," complying with the "Safety Regulations for Metal and Nonmetal Mines" to build a comprehensive "personnel - equipment - area" safety barrier for mines.

III. Core Advantages:

Tailored to the harsh mining conditions (dust, slag, corrosive water), high operational intensity (blasting, heavy equipment), complex terrain (steep slopes, tunnels), and stringent safety standards, it highlights key differences from ordinary protective nets:

1. Impact and Rockfall Resistance, Fortifying High-Risk Zones

• High-Strength Material and Toughness Design:
  • Uses Q460 low-alloy high-strength steel wire (preferred for open-pit mines, 30% better impact resistance than ordinary steel) or 65Mn spring steel wire (for underground use, high toughness against frequent collisions), with wire diameters of 4.0-6.0mm (5.0-6.0mm for blast zones, 4.0-5.0mm for regular areas). Tensile strength ≥800MPa, elongation at break ≥15%, capable of withstanding 50kg rockfall impact (speed ≤30km/h), blast shockwaves (≤0.2MPa), and minor scrapes from heavy equipment (e.g., loaders) without tearing or significant deformation, effectively blocking rockfall and slag.
• Targeted Protection Design:
  • Mesh Size Adaptation: 8cm×15cm for open-pit slopes (blocks large rocks while allowing water drainage); 5cm×5cm for underground tunnel entrances (prevents small slag fall without obstructing ventilation); 6cm×6cm for equipment area isolation (prevents unauthorized entry and withstands equipment impact).
  • Weaving Process: Uses "double-twist reinforced gabion" technique, with node engagement strength ≥90% of mesh strength. Distributes impact force through overall elasticity (50% better tear resistance than welded mesh), avoiding localized failure.

2. Wear and Corrosion Resistance, Adapts to Harsh Mine Conditions

• Resistance to Abrasion and Slag Erosion:
  • Surface treated with "hot-dip galvanizing + plastic coating" dual protection (zinc layer ≥120μm, coating thickness ≥1.0mm), withstands salt spray test ≥800 hours, resistant to acidic mine water (pH≤5), dust abrasion, and slag accumulation corrosion (service life 2x longer than ordinary galvanized mesh).
  • Wire undergoes "hardening treatment" (surface hardness ≥HV500), reducing wear from frequent contact with mine carts, loaders, etc., ideal for material yards and transport pathways.
• Full Environmental Tolerance:
  Adapts to underground high humidity (≥90%) and open-pit extreme temperatures (-30°C to 60°C) without brittleness or coating peeling, ensuring long-term stability (service life 8-12 years in open-pit, 10-15 years underground).

3. Scenario-Based Customization, Comprehensive Mine Area Coverage

• Scenario-Specific Design:
  • Open-Pit Slope Protection: Mesh width 2-4m, laid along slopes (≤70° incline), buried 50cm underground (prevents sliding), top fixed with anchor bolts (spaced 2-3m) for integrated "mesh - anchor - slope" reinforcement, reducing collapse risk.
  • Underground Tunnel / Shaft Entrance Protection: 5cm×5cm mesh, height 1.8-2.5m, blocks post-blast debris, prevents falls of personnel or tools; edges fitted with "anti-scrape rubber strips" to avoid friction damage with tunnel walls.
  • Equipment and Material Yard Isolation: 6cm×6cm or 8cm×8cm mesh demarcates zones for excavators, crushers, etc., keeping non-operators away; isolates slag piles from work areas, preventing slag slides from burying equipment.
• Flexible Installation and Reusability:
  Includes "mine-specific fixtures" (high-strength anchor bolts, explosion-proof clamps) for secure attachment to rock, concrete, soil, etc. Installation is 3x faster than rigid barriers (e.g., concrete walls), and mesh can be reused after relocation (residual value ≥40%), reducing mine costs.

IV. Technical Parameters:

V. Applicable Scenarios: Full Mine Operation Coverage

• Core Protection Areas:
  • Open-Pit Mining Areas: Slopes, benches, blast警戒 zones; prevents rockfall and collapse, protects personnel and equipment.
  • Underground Tunnels: Shaft entrances, tunnel intersections, behind excavation faces; blocks debris, prevents falls.
  • Processing Plants / Material Yards: Around slag and raw material piles; isolates hazardous areas, prevents slag slides or vehicle误入.
  • Mine Roads: Along transport routes; protects against slope rockfall, ensures safe vehicle passage.

VI. Service Support: Compliant Mine Safety Solution

• Customized Solutions: Professional team (including mine safety engineers) conducts on-site surveys (following mine safety regulations). Based on geological reports (slope gradient, rock type) and hazard levels, provides tailored "mesh size + wire diameter + fixation method" plans within 7 days (e.g., "6.0mm wire + 8cm mesh +密集 anchors for blast zones").
• Compliance Assistance: Provides full test reports (impact resistance, corrosion resistance), complies with "Safety Regulations for Metal and Nonmetal Mines" (AQ 2007-2010), aids in passing mine safety bureau inspections.
• Supply Chain & After-Sales:
  • In-house factory production capacity ≥1000㎡/day; standard custom orders delivered in 10-15 days; dedicated mine logistics (including short-haul transport in mining areas); bulk orders (≥1000㎡) receive exclusive discounts.
  • Provides "Mine Installation Manual" (includes blast zone safety guidelines); supports installation by "mine-designated teams" or on-site guidance by our technicians (requires mine safety training).
  • 5-year warranty (free replacement for non-blast damage); lifetime "wear assessment" service (regular alerts for partial replacements to prevent failure).
