Wire mesh is commonly used for rock support in mining, tunneling, and slope stabilization. It plays a critical role in ensuring ground stability and protecting against rockfalls. Below are its primary uses:
1. Rockfall Protection
- Prevention of Loose Rock Falling: Wire mesh is applied to hold loose rocks or small fragments in place, preventing them from falling and causing hazards in mining or tunneling operations.
- Surface Stabilization: It ensures surface stability in slopes or rock faces where loose or fractured rock may pose a threat.
2. Reinforcement in Ground Support Systems
- Combination with Shotcrete: Wire mesh is often used in conjunction with shotcrete to enhance surface bonding and increase the structural strength of the applied shotcrete layer.
- Support with Rock Bolts: The mesh is secured using rock bolts to form a comprehensive support system that provides added strength and stability to the rock surface.
3. Slope Stabilization
- Erosion Control: On slopes, wire mesh helps prevent soil and rock erosion by stabilizing the surface and controlling runoff.
- Vegetation Support: In some cases, it can support vegetation growth, further stabilizing the slope over time.
4. Tunneling and Mining Applications
- Protecting Workers and Equipment: In tunnels or underground mines, wire mesh creates a protective barrier to safeguard workers and machinery from falling debris.
- Used as Part of a Primary Support System: Especially during the early stages of excavation, it provides immediate stabilization until permanent support is installed.
5. Customization for Specific Needs
- Wire mesh can be made from galvanized or stainless steel for enhanced corrosion resistance, especially in environments with high moisture or chemical exposure.
- Mesh size, wire thickness, and strength are customizable to suit specific project requirements.
Wire mesh is a versatile and essential component in modern rock support systems, improving safety and ensuring the longevity of mining and construction projects.
