Introduction
In underground mining, mining support systems — such as Split Set bolts, welded wire mesh, metal formwork, and shotcrete — are the first line of protection to ensure underground safety and operational continuity. However, their effectiveness largely depends on regular preventive maintenance, which allows anticipating and correcting possible failures before they pose a risk to workers and infrastructure.
What is preventive maintenance in underground mining?
Preventive maintenance consists of a series of inspections, reviews, and planned actions to verify the condition and functionality of the mining support elements. Its goal is to identify wear, corrosion, deformations, or any structural damage that may compromise the integrity of the support system, and act before an incident occurs.
Benefits of preventive maintenance in mining support systems
1. Accident prevention and life protection
A support system in optimal condition reduces the risk of rockfalls, collapses, or detachment, protecting workers’ lives and ensuring a safe working environment.
2. Longer equipment and material lifespan
Periodic inspection and proper maintenance prevent premature deterioration of bolts, meshes, formwork, and shotcrete, maximizing their lifespan and the return on investment.
3. Reduction of operating costs and unexpected downtime
Detecting and fixing problems before they evolve into major failures avoids high emergency repair costs and reduces mining operation downtime.
4. Regulatory compliance and audits
Mining safety regulations in Peru and worldwide require maintenance plans and inspection records for support systems. A good preventive program helps comply with regulations and facilitates audit approvals.
5. Optimization of productivity and operational continuity
A safe and stable underground environment allows operations to continue without interruptions, improving productivity rates and overall mine efficiency.
Main actions in preventive maintenance of mining support
- Regular visual inspection of Split Set bolts, mesh, and formwork to identify signs of wear, corrosion, or deformation.
- Verification of bolt fixation and tension and connections.
- Cleaning and removal of loose material that may conceal damage in the support systems.
- Detailed recording of inspections and repairs carried out, creating a technical history.
- Continuous training of personnel in charge of inspections to ensure correct risk assessment and corrective actions.
