Introduction: The Unseen Guardian of Mine Safety
In global mining operations, chain link mesh serves as a vital ground control solution, reducing roof collapse incidents by over 60% (ISO 14628:2020 certified). This engineered barrier combines high-tensile strength with impact resistance to create mining’s first line of defense.
1. Technical Specifications Under International Standards
1.1 Material & Construction
-
Core Material: ASTM A641 low-carbon galvanized steel wire (Tensile strength ≥550 MPa)
-
Mesh Geometry: 80×80mm or 100×100mm openings (MSHA Part 48 compliant)
-
Edge Reinforcement: Helical wire locking per EN 10223-3 (40% tear resistance boost)
1.2 Performance Metrics
Parameter | Int'l Standard | FunctionTensile Strength |
---|---|---|
Tensile Strength | ≥50 kN/m (ISO 14628) | Resists strata pressure |
Elongation Rate | ≤12% (AS/NZS 1742) | Absorb kinetic energy |
Corrosion Resistance | Zinc coating ≥220g/m² | Long-term humidity protection |
2. Critical Functions in Ground Control
