Introduction: The key to success in underground mining
Choosing the right mining support system is one of the most important decisions in any underground mining operation. Selecting the appropriate solution not only ensures underground safety and worker protection, but also optimizes costs, extends the lifespan of excavations, and maintains high levels of productivity.
Key factors for choosing a mining support system
When selecting the ideal support system, it is essential to analyze several technical and operational factors. Among the most important are:
1. Geomechanical conditions of the ground
Each mining deposit presents particular geological and geomechanical characteristics. The type of rock, presence of fractures, humidity, and stability of the rock mass directly influence the choice of the support system. A complete geotechnical study is the first step to making an informed decision.
2. Depth and dimensions of the excavation
The dimensions of tunnels, galleries, or underground chambers determine the magnitude of the loads the support system must withstand. Deeper or larger excavations require more robust solutions and combined reinforcement systems.
3. Operational and environmental conditions
Factors such as the presence of groundwater, temperature variations, seismic activity, or exposure to corrosive substances can affect the durability and performance of the support system. It is essential to choose corrosion-resistant materials adapted to demanding environments.
4. Advance rate and expected productivity
In operations where advance speed is a priority, such as large-scale mining, it is advisable to opt for support systems with quick installation and immediate support, like Split Set bolts. This reduces downtime and maintains project continuity.
5. Safety regulations and standards
Compliance with national and international mining safety regulations is mandatory. Ensure that the selected support systems have the certifications and technical documentation required by the competent authority, as well as the supplier’s follow-up if any incidents are detected.
Most commonly used support system types
1. Split Set bolts:
Provide immediate support and are ideal for fractured ground or areas requiring fast installation. Their versatility and ease of monitoring make them the preferred option in modern underground mining.
2. Welded wire mesh:
Perfect for reinforcing tunnel surfaces and preventing the fall of small or medium fragments. Used in combination with bolts to provide comprehensive support.
3. Metal formwork:
Suitable for soft ground zones or large excavations where additional structural reinforcement is needed.
4. Shotcrete (sprayed concrete):
Provides a rigid layer that consolidates the excavation surface and improves load distribution.
