Product description
1. Product Overview
The Underground Mine Local Ventilation Fan is an axial flow auxiliary ventilation fan designed to provide fresh air to underground mining headings, roadways, working faces and other localized areas that cannot be adequately ventilated by the main mine ventilation system.
The fan is normally installed close to the underground working area and connected to a flexible or rigid ventilation duct. It delivers fresh air over the required ventilation distance and supports continuous airflow at the mining face.
Typical applications include:
Underground metal mines
Gold mines
Copper mines
Iron ore mines
Nickel mines
Underground coal mines
Non-coal mines
Mine development headings
Blind roadways
Underground tunnels
Mining construction projects
In industry product descriptions, mine auxiliary fan and local ventilation fan are commonly used for fans serving specific underground headings through ducting, rather than the mine-wide primary ventilation network.

4. Product Applications
Underground Mine Development
The fan is designed for localized ventilation during underground development.
Typical applications:
Development headings
Blind headings
Crosscuts
Drifts
Raises
Declines
Excavation faces
Mine Heading Ventilation
A local fan can deliver fresh air through a duct directly to the heading.
Typical airflow arrangement:
Fresh Air
↓
Local Ventilation Fan
↓
Ventilation Duct
↓
Development Heading
↓
Working Face
↓
Return Air
This configuration is particularly useful when the working face advances away from the main ventilation airway.
5. Metal Mine Applications
The fan can be configured for underground:
Gold Mines
Copper Mines
Iron Ore Mines
Nickel Mines
Lead-Zinc Mines
Manganese Mines
Other Non-Ferrous Mines
For metal and non-coal mines, FK/FKD-type auxiliary axial fans are commonly positioned for local duct ventilation, with the required fan selected according to airflow, pressure and duct resistance.
6. Coal Mine Applications
For coal mining projects, the product can be configured according to the required explosion-protection and mine safety requirements.
Possible positioning:
Explosion-Proof Underground Mine Local Ventilation Fan
Flameproof Mine Auxiliary Ventilator
Coal Mine Auxiliary Ventilation Fan
Explosion-Proof Axial Flow Mine Fan
For hazardous coal-mine environments, explosion-proof motors, electrical equipment and other safety-related configurations must be specified according to the applicable mine classification and destination-market requirements. Existing industry products explicitly position flameproof auxiliary fans for methane-hazard environments.
7. Main Product Structure
A typical underground local ventilation fan consists of:
1.Fan casing
2.Axial impeller
3.Motor
4.Guide vane
5.Air collector
6.Protective guard
7.Duct connection
8.Supporting frame
9.Electrical control system
Optional components may include:
Silencer
Flexible ventilation duct
VFD
Control cabinet
Monitoring system
Explosion-proof motor
Vibration monitoring
8. High-Efficiency Axial Flow Design
The axial-flow configuration is suitable for moving large quantities of air through ventilation ducts while maintaining a compact installation footprint.
Key characteristics:
High airflow capacity
Stable pressure performance
Compact structure
Direct-drive configuration
Convenient duct connection
Easy relocation underground
9. High-Pressure Configuration
For long-distance underground ventilation, fan selection must account for the pressure required to overcome the resistance of the complete duct system.
The basic relationship is:
Longer Duct → Higher Resistance → Higher Required Fan Pressure
The selection should therefore not be based only on motor power or fan diameter.
Required information includes:
Airflow
Static/total pressure
Duct diameter
Duct length
Number of bends
Duct leakage
Operating temperature
Installation altitude
Industry selection guides similarly recommend determining the fan from the complete ventilation duty rather than selecting only from the model or motor size.
10. Single-Stage Axial Fan
Standard Local Ventilation
The single-stage configuration is suitable for conventional local ventilation where the required operating pressure can be achieved by one impeller stage.
Typical applications:
Short-distance duct ventilation
Medium-distance duct ventilation
Standard development headings
Underground construction
11. Counter-Rotating Axial Fan
High-Pressure Local Ventilation
For demanding ventilation systems, a counter-rotating configuration can be used.
The two impellers rotate in opposite directions, allowing the fan to develop higher pressure for applications with greater system resistance.
Typical applications:
Long ventilation ducts
Deep underground headings
High-resistance systems
Large excavation projects
Current FKD-type product information, for example, lists configurations reaching approximately 9,950 Pa total pressure, demonstrating the type of higher-pressure duty available from counter-rotating auxiliary fans. Actual selection must be based on the required operating point.
12. Explosion-Proof Configuration
For hazardous underground environments, an appropriate explosion-protected configuration can be supplied where required.
Possible configuration:
Explosion-Proof Motor
Anti-Sparking Components
Grounding System
Explosion-Proof Electrical Control
The precise certification should always be specified according to the destination country and project requirements rather than simply claiming “explosion-proof” without identifying the applicable standard.
