Introduction to Ventilation on Demand (VOD)
Definition:
- VOD is a system designed to dynamically adjust airflow in underground mines based on real-time needs.
- Replaces traditional constant airflow systems with smarter, energy-efficient solutions.
Why It Matters:
- Energy costs of mine ventilation constitute 40–50% of total energy consumption.
- Enhances safety by ensuring optimal air quality tailored to mining zones.
Core Components:
- Sensors: Monitor air quality, temperature, humidity, and gases in real time.
- Variable Frequency Drives (VFDs): Adjust fan speeds to match ventilation demands.
- Centralized Control Systems: Automate and optimize airflow using advanced algorithms.
Implementation Levels:
- Basic: Manual adjustments based on sensor data.
- Intermediate: Partial automation using VFDs and control systems.
- Advanced: Fully automated systems with AI and IoT integration.
