The trend toward large diesel-powered LHDs (Load-Haul-Dump) and haul trucks has driven up ventilation requirements. Regulations often require 0.06 m³/s per kW of diesel power. A single 300 kW loader demands 18 m³/s of fresh air just for itself.

Humans require at least 19.5% oxygen by volume. Combustion engines (loaders, trucks) consume oxygen and produce CO2. The ventilation system maintains a steady influx of O2. The ventilation system maintains a steady influx of O2

Traditional fans run at 100% speed regardless of where miners are. uses RFID tags on miners and equipment, plus air quality sensors, to automatically ramp up fan speed only in active zones. This can cut energy consumption by 40-60%. sucking air through the mine.

The main fan is located on the return shaft, sucking air through the mine.
