3. Product Overview
The Metal Mine Local Ventilation Fan is an axial flow auxiliary ventilation fan designed for underground metal mines and non-coal mining operations.
It provides fresh air to underground working areas through flexible or rigid ventilation ducts, especially where the main mine ventilation system cannot deliver sufficient airflow directly to an advancing working face.
The fan is suitable for:
Gold mines
Copper mines
Iron ore mines
Nickel mines
Lead-zinc mines
Manganese mines
Non-ferrous metal mines
Underground construction projects
Typical applications include development headings, drifting, blind roadways, mining faces and other underground areas requiring localized forced ventilation.
4. How the Metal Mine Local Fan Works
A typical local ventilation system operates as follows:
Fresh Air

Metal Mine Local Ventilation Fan

Flexible Ventilation Duct

Underground Development Heading
↓
Mining Working Face

Contaminated Air Returns Through the Mine Ventilation Network
The fan supplies fresh air directly to the working face and helps dilute and remove dust, blasting fumes and other contaminants.
For underground metal mine development, the ventilation duct becomes an important part of the system because increasing duct length and resistance can reduce the airflow reaching the working face.
5. Main Applications
Underground Metal Mining
The fan can be used for:
Underground gold mining
Copper mine ventilation
Iron ore mine ventilation
Nickel mine ventilation
Lead-zinc mine ventilation
Non-ferrous metal mining
Hard-rock mining
Development Heading Ventilation
Particularly suitable for:
New roadway development
Drift excavation
Blind headings
Crosscuts
Raise development
Underground excavation
Mining Face Ventilation
The fan supplies fresh air to areas where drilling, blasting, loading and other mining activities are performed.
Main functions include:
Supplying fresh air
Diluting blasting fumes
Controlling dust
Improving airflow circulation
Supporting underground working conditions
6. FK Series — Single-Stage Local Ventilation Fan
The FK Series is recommended for conventional local ventilation duties where the required airflow and system resistance can be satisfied by a single-stage axial fan.
Recommended Applications
Short-to-medium ventilation distances
Normal development headings
Conventional metal mine ventilation
Underground construction
A current FK product range lists airflow of approximately 0.9–17.8 m³/s, total pressure of 475–3,776 Pa, with different models and motor configurations available. Actual selection should be based on the project operating point rather than these ranges alone.
7. FKD Series — High-Pressure Counter-Rotating Fan
The FKD Series uses two counter-rotating impellers and is intended for applications requiring higher pressure or longer duct ventilation.
Recommended Applications
Deep underground mines
Long development headings
Long ventilation ducts
High-resistance systems
Large underground excavation projects
Current FKD product information shows configurations covering approximately 1.42–31.33 m³/s and 270–9,950 Pa, depending on model and motor configuration.
8. FK vs FKD
Feature FK FKD
Fan type Single-stage axial Counter-rotating axial
Application Conventional local ventilation High-pressure local ventilation
Ventilation distance Short/medium Medium/long
System resistance Normal Higher
Structure Single impeller Two counter-rotating impellers
Typical application Development headings Deep/long headings
Maintenance Simple More complex
Selection Normal local ventilation High-pressure requirements
Important: The model should be selected according to the actual operating point, duct system and mine ventilation resistance rather than simply choosing the largest motor.
