Permanent and Temporary Ventilation Solutions for Tunnels and Mines
Permanent Tunnel Ventilation
Permanent tunnel ventilation systems are designed to provide long-term, continuous airflow in infrastructures like railway tunnels, metro tunnels, and road tunnels. These systems form a core part of any modern tunnel ventilation system, ensuring safety, comfort, and energy efficiency for decades.

Permanent tunnel ventilation is essential for the long-term reliability of underground infrastructure, ensuring both safety and sustainability.
Features of Permanent Ventilation Systems
Continuous Operation: Permanent solutions run 24/7 to maintain stable air quality.
Emergency Smoke Extraction: In case of fire, these systems quickly remove smoke and guide safe evacuation.
Integration with VFDs: By using Variable Frequency Drives (VFDs), operators can regulate fan speeds based on demand, lowering energy consumption.
Mining Ventilation Control: In underground mining projects, permanent systems ensure compliance with safety standards while optimizing airflow.
Applications:
- Railway Tunnel Ventilation → Designed for high-speed trains, managing aerodynamics and emergency smoke control.
- Ventilation Solutions for Metro → Keep stations and running tunnels comfortable and energy-efficient.
- Road Tunnels → Maintain visibility, remove exhaust gases, and supply fresh air for vehicle traffic.
Purpose and Function
- Air Quality Control → Removes dust, mist, fumes, and toxic gases generated by blasting, drilling, or boring.
- Fresh Air Supply → Dilutes pollutants and creates a breathable atmosphere for workers.
- Temperature Control → Helps cool down the working environment heated by rock mass, machinery, and concrete curing.
- Booster Stations → Installed in long tunnels to increase airflow with in-line fans
Examples of Use
- Drill and Blast → Removes dust and toxic gases after blasting.
- Trenching → Used when prefabricated tunnel sections are placed in trenches.
- Tunnel Boring Machines (TBM) → Ventilation required for heat and gas management during boring.
Temporary Tunnel Ventilation
Unlike permanent systems, temporary tunnel ventilation is used during tunnel construction and mining operations. It plays a vital role in ensuring worker safety before a permanent solution is installed.
Temporary ventilation for tunnels during construction uses systems of large industrial axial fans connected to flexible air ducts to supply fresh air and remove dust, fumes, and toxic gases from the working environment. These systems are adaptable to growing construction needs and may include booster fans, filtering, or cooling devices.
Components and Types
- Axial Fans → Large industrial fans moving significant volumes of air
- Flexible Ducts → Transport fresh air from the entrance to the work face or extract polluted air
- Mobile Ventilation Units → Movable fans placed on platforms or cars for flexible airflow
- Booster Stations → Installed in long tunnels to increase airflow with in-line fans
Key Considerations
- Flexibility → Must adapt to tunnel growth and changing construction phases.
- Safety → Provides fresh air and removes hazardous gases to prevent accidents.
- Logistics → Large ducts may affect movement of construction equipment.
Temporary tunnel ventilation is therefore indispensable during the construction stage of tunnels and underground mining projects, creating a safe and workable environment for crews until the permanent system is established.
