Introduction to mine support
Mine support is one of the fundamental practices to ensure safety and efficiency in underground mining operations. It involves implementing various support and reinforcement systems that maintain the stability of tunnels, galleries, and other underground excavations, preventing collapses, rock falls, and accidents that could endanger both workers and mining infrastructure.
Importance of support in underground mining
In underground mining, geological conditions are often unpredictable. Soils and rocks can have fractures, unstable zones, or even experience movements due to material extraction. Without an adequate support system, tunnels would be exposed to detachments and landslides, significantly increasing operational risks.
Mine support serves a dual purpose:
- Safety: Protects the lives and health of workers by creating a controlled environment and minimizing the risk of serious accidents.
- Productivity: Allows continuous operations by avoiding stoppages caused by collapses and reducing costs derived from repairs and emergencies.
Main mine support systems
There are several support systems used in underground mining, each adapted to the terrain characteristics and specific project needs. The most commonly used include:
- Split Set Bolts
Split Set bolts are high-strength steel rods inserted into drilled holes in the rock. By expanding, they exert pressure and generate friction, stabilizing the rock mass immediately. Their quick installation and ability to adapt to different rock types make them a preferred solution for tunnel support.
- Welded Mesh
Meshes are placed over the tunnel surface to prevent the fall of small to medium rock fragments. Combined with bolts, they offer comprehensive reinforcement and greater safety for workers moving through the galleries.
- Metal Formwork
Steel structures installed on tunnel walls and ceilings to provide additional structural support. They are ideal for soft ground areas or when temporary reinforcement is needed during excavation.
- Shotcrete
Shotcrete, or sprayed concrete, is applied directly to the excavation surface, creating a rigid layer that helps consolidate the rock and distribute loads.
Benefits of mine support in underground safety
Implementing an adequate mine support system significantly reduces accident risks while complying with safety regulations and international standards. Key benefits include:
- Prevention of collapses and rock falls
- Protection of workers and equipment
- Longer lifespan of excavations
- Reduced costs from emergencies and repairs
- Compliance with current mining regulations
