Research on Maintenance and Management of Mining Machinery

Scientific maintenance and management are critical to ensure stable operation of mining machinery. This article summarizes common problems, causes, and optimized strategies to extend service life, reduce failures, and improve safety and efficiency.

1. Common Problems in Mining Machinery

• Short service life: obvious aging occurs within 6–8 years
• Outdated maintenance modes and low technical levels
• Incomplete management systems and unclear responsibilities
• Unstandardized operation and frequent man-made faults

2. Main Causes of Equipment Issues

• Technical factors: outdated technology, lack of personnel training
• Management factors: imperfect systems, poor supervision
• Environmental factors: harsh conditions accelerate wear and corrosion
• Human factors: unregulated operation, weak maintenance awareness

3. Optimization of Maintenance Work

3.1 Routine Maintenance

• Comprehensive inspection after each shift
• Record operating parameters for trend analysis
• Timely handling of hidden dangers to avoid faults

3.2 Preventive Maintenance

• Customized maintenance plan for each equipment
• Regular maintenance for long-term idle equipment
• Replace worn and rusted parts in advance

3.3 Structural Fault Repair

• Accurate diagnosis of root causes
• Local repair to restore function quickly
• Scrap equipment that cannot be repaired to avoid risks

4. Optimization of Management Measures

• Standardize operation to reduce failure rates
• Combine regular and irregular maintenance
• Strengthen daily inspection of key indicators
• Build information-based and intelligent management systems
• Implement TPM (Total Productive Maintenance) mode

5. Key Inspection Items

• Temperature monitoring: prevent overheating damage
• Noise monitoring: early warning of wear and faults
• Performance monitoring: load, speed, efficiency
• Lubrication system: oil quality, level, pipeline

6. Benefits of Optimized Management

• Extend equipment service life beyond 6–8 years
• Reduce failure rate and unplanned downtime
• Lower maintenance cost and production loss
• Improve operational safety and production efficiency

7. Conclusion

• Scientific maintenance ensures long-term stable operation
• Standardized management reduces risks and costs
• Intelligent systems improve efficiency and accuracy
• Supports safe, efficient, and sustainable mining
