Use of IoT & Artificial Intelligence in Mining Industry for Smart Energy Management

How IoT (Internet of Things) and Artificial Intelligence (AI) are used in the mining industry for smart energy management, with detailed system components, workflows, and benefits

✅ 1. Why Smart Energy Management Matters in Mining

Mining is an energy-intensive industry, with operations consuming energy across:

• Drilling & blasting
• Haulage (diesel-powered and electric fleets)
• Crushing, grinding, and ore beneficiation
• Pumping (dewatering, slurry transport)
• HVAC systems in underground mines
• Lighting, ventilation, compressors, and processing plants

Energy costs can account for 25–40% of operating expenses. Hence, optimizing energy use with IoT sensors and AI algorithms is critical for reducing costs and carbon footprint while ensuring uninterrupted operations.

🛰️ 2. IoT Applications in Smart Energy Monitoring

A. Smart Energy Metering

• IoT-connected energy meters (electricity, diesel, gas) installed at:
  • Substations, MCC panels, gensets, compressors
  • Remote mining equipment
  • Ore processing plants
• Monitors:
  • kWh, kVA, Power Factor
  • Voltage and current imbalance
  • Load patterns

B. Diesel Fuel Monitoring

• IoT fuel level sensors on:
  • Haul trucks, loaders, excavators, and generators
• Monitor:
  • Fuel fill, consumption, and refueling cycles
  • Leak detection and theft prevention

C. Thermal and Vibration Sensors

• Track energy loss from motors, drives, belts, and heat exchangers
• Installed in crushers, conveyors, mills

D. Environmental Sensors

• Monitor temperature, humidity, pressure to optimize HVAC and ventilation in underground operations

🧠 3. AI Applications for Energy Optimization

A. Predictive Load Management

• AI models forecast peak load times based on:
  • Shift schedules
  • Equipment operating cycles
  • Historical consumption
• Enables load leveling and demand response strategies (e.g., turning off non-critical loads during peak tariffs)

B. Energy Usage Pattern Recognition

• AI clusters and classifies energy profiles for:
  • Inefficient vs optimal machine cycles
  • Operator behavior affecting energy use
  • Abnormal spikes indicating leaks or faults

C. Predictive Maintenance for Energy-Draining Equipment

• Anomaly detection on:
  • Overheating motors
  • Low-efficiency compressors
  • Leaky pumps
• Reduces unplanned energy-intensive breakdowns

D. Smart Scheduling of High-Load Equipment

• AI algorithms optimize operating schedules:
  • Crusher, ball mill, ventilation fans
  • Charging stations for EV mining trucks
• Based on tariff windows, solar/wind availability, and productivity targets

E. Integration with Renewable Energy Sources

• AI manages microgrids by:
  • Balancing diesel gensets with solar PV, wind, and batteries
  • Prioritizing clean energy use while maintaining power quality
