Product description

Underground Mining Explosion-Proof Auxiliary Ventilation Fan
Flameproof Local Ventilation Fan for Underground Coal Mines, Metal Mines and Tunnel Applications
Product Overview
The Underground Mining Explosion-Proof Auxiliary Ventilation Fan is a specialized axial flow ventilation fan designed for underground mining operations, tunnel excavation and other confined underground environments requiring reliable local airflow supply.
The fan provides fresh air to working faces, excavation headings, blind tunnels, underground chambers and other areas where the main mine ventilation system cannot provide sufficient airflow.
EMS supplies customized flameproof mining auxiliary ventilation fans for underground coal mines, metal mines, non-metal mines, tunneling projects and industrial underground applications.
These fans are typically connected with flexible ventilation ducts to deliver fresh air over medium and long distances, helping improve underground air circulation and working conditions.

Product Name
Underground Mining Explosion-Proof Auxiliary Ventilation Fan
Alternative names:
Underground Mine Auxiliary Fan
Flameproof Auxiliary Ventilation Fan
Explosion-Proof Mining Ventilation Fan
Mine Local Ventilation Fan
Underground Tunnel Ventilation Fan
FBD Series Mining Fan
Counter-Rotating Axial Mining Fan

Main Applications
Underground Coal Mine Ventilation
The fan is widely used for:
Coal mine excavation faces
Development roadways
Blind headings
Gas-risk areas
Underground chambers
Mining tunnels
For underground coal mines, explosion-proof construction is essential where combustible gases such as methane may exist.

Metal Mine Ventilation
Suitable for underground ventilation applications in:
Gold mines
Copper mines
Iron mines
Nickel mines
Lead-zinc mines
Other hard-rock mines

Tunnel Construction Ventilation
Applicable for:
Railway tunnels
Highway tunnels
Underground construction
Hydropower tunnels
Underground engineering projects

Product Features
1. Explosion-Proof / Flameproof Design
The fan is designed for underground hazardous environments requiring enhanced safety performance.
Features include:
Explosion-proof motor
Flameproof electrical components
Anti-static structure
Reliable grounding
Spark-resistant design options
Industrial safety configuration
Certification requirements vary by country and project, including possible IECEx, ATEX, MSHA or local mining certification requirements.

2. High Pressure Air Supply
Underground ventilation systems often have high resistance caused by:
Long ventilation ducts
Multiple bends
Narrow underground passages
Duct leakage
Long-distance air delivery
The fan can be configured for high-pressure operation according to actual ventilation requirements.

3. Counter-Rotating Axial Fan Design
For demanding underground ventilation applications, counter-rotating axial fans can provide higher pressure capability.
Typical structure:
First Impeller + Second Impeller + Two Independent Motors
The two impellers rotate in opposite directions to increase airflow energy and improve pressure performance.
Counter-rotating FBD-type fans are commonly used for underground auxiliary ventilation where higher pressure and longer duct distances are required.

4. Long-Distance Ventilation Capability
The fan can supply air through flexible ducts over long distances.
Suitable for:
Deep underground headings
Long tunnel excavation
Large underground chambers
Remote working faces

5. Low Noise Operation
Underground workers may operate close to ventilation equipment.
Optional noise reduction features:
Silencer section
Optimized impeller design
Vibration isolation
Low-noise motor selection
