Mine safety is a comprehensive system covering critical areas:
Slope Stability Monitoring
Key risks: Displacement, deformation, and landslides in high/steep slopes (common in open-pit mines).
Equipment Safety & Maintenance
Regular checks for blasting equipment, transport machinery, and electrical systems. Example: DTH drills without dust collectors violate regulations.
Hydrology & Weather Monitoring
Blocked drainage channels or heavy rain may trigger dam failures or landslides.
Tailings Pond Management
Core indicators: Seepage line monitoring, dry beach length control, and dam displacement.
Worker Safety & Training
Use VR simulations and smart training systems to improve emergency response skills.
Dam Collapse
Caused by structural instability or heavy rain, leading to casualties and environmental damage.
Seepage & Piping
Abnormal seepage line levels may cause internal erosion.
Landslides & Subsidence
Over-stacked tailings or unstable geology increase local landslide risks.
Environmental Pollution
Leakage can contaminate soil and water with heavy metals.
This standard focuses on safety monitoring for high/steep slopes in non-coal open-pit mines:
Scope
Applies to non-coal mines; natural slopes may follow guidelines.
Monitoring Levels
Four risk levels (I to IV) based on slope height, angle, geology, and landslide risks. Reassess every 3 years.
Monitoring Requirements
Deformation (displacement, cracks), stress (blasting vibrations), and hydrometeorology (rainfall, groundwater).
Warning System
Three-tier alerts (e.g., yellow/orange/red) with predefined thresholds.
System Compliance
Monitoring systems must run error-free for 3 months before approval. Supports manual data entry and alerts.
Design Principles
Temporary monitoring during early phases; permanent systems for final slopes.
Technologies
BeiDou Satellite Monitoring: 24/7 mm-level displacement tracking.
AI Video Analytics: Detects fires, missing helmets, or equipment leaks.
Drone Inspections: Reaches inaccessible areas.
Data Management
Auto-generates reports, multi-device access, and links to emergency platforms.
| Equipment | Function |
|---|---|
| GNSS Monitoring Station | Tracks horizontal/vertical displacement (mm-level). |
| Stress Sensors | Detects rock stress changes for landslide alerts. |
| AI Video Systems | Identifies hazards (e.g., safety violations). |
| Hydrometeorological Stations | Monitors rainfall, groundwater, wind speed. |
| Inspection Robots | Replaces manual checks in hazardous zones. |
Precision & Reliability
GNSS stations: ≤6mm horizontal / ≤3mm vertical accuracy.
Environmental Adaptability
IP67-rated, withstand -20°C to 60°C. Solar-powered for remote areas.
Data Integration
Unified platforms for sensor data, drones, and manual logs. AI reduces false alarms.
Low Maintenance
Mobile GNSS stations for dynamic mining sites; remote troubleshooting.
Regulatory Compliance
Meets AQ/T 2063-2018 and GB 16423 standards. Requires 3-month error-free testing.
Reduced Accidents
Shanxi Coking Coal cut costs by ¥326/ton (2024) with zero landslides.
Efficiency Gains
Drones inspect remote zones 10x faster than humans.
Cost Savings
AI slashed false alarms from 3,035 to 261/day, cutting labor costs by 90%.
Compliance & Sustainability
Real-time tailings data prevents pollution; auto-reports to regulators.
Gansu Open-Pit Mine
Deployed 73 GNSS stations for 150m slopes. Achieved 100% online rate and national data sharing.
Shanxi Coking Coal
AI robots and "one-click control" reduced underground staff by 30%.
Guizhou Drone Patrols
Drones reach accident sites in 5 minutes, boosting emergency response by 80%.
Scope
Non-coal mines only; natural slopes as reference.
Risk Levels
Four tiers based on height (<100m = low; ≥200m = high) and safety factors (F<1.05 = high risk).
Technical Standards
Deformation (mm precision), stress, and hydrometeorology (per SL 21/SL 183).
Alerts & Compliance
Three-tier warnings with automatic alarms. Systems must pass 3-month trials.
Data stored for 10+ years.
