This underground mining ventilation fan is designed for forced-air ventilation in mine headings, tunnels, and other underground work areas. The correct choice depends on airflow, pressure loss, duct layout, electrical supply, installation space, and the ventilation plan for the site.
This underground mining ventilation fan is designed for forced-air ventilation in mine headings, tunnels, and other underground work areas. The correct choice depends on airflow, pressure loss, duct layout, electrical supply, installation space, and the ventilation plan for the site.
A ventilation fan should be evaluated as part of the ducted circuit, not as an isolated motor. Confirm the required air volume at the working face, system resistance, duct extension method, leakage, duty cycle, and environmental conditions. Zongda Mining can use these inputs to prepare a configuration for the project.
Airflow and pressure should be checked together with duct length, bends, leakage, and face distance so the fan operates where the circuit needs it.
Confirm fan diameter, duct interface, motor rating, voltage, frequency, starting method, and control requirements for the local installation.
For advancing headings, the duct and fan arrangement may change as the face moves. Discuss extension, relocation, support, and access requirements early.
Request the operating limits, inspection points, cleaning method, spare-parts list, wiring information, and commissioning documents with the supply.
| System | K-series supplied configuration |
| Product family | K/DK main and auxiliary fans; JK/DJK local fans for non-coal mine ventilation |
| Local fan types | JK-1 single-stage, JK-2 double-stage, and DJK contra-rotating configurations |
| Air performance | Airflow and total pressure combinations selected for the duct network; supply distance 80–600 m, over 1,200 m in series |
| Blade and airflow | Adjustable blade installation angle; reversible airflow direction for ventilation requirements |
| Drive and installation | Direct motor/impeller connection; two-pole motor at 2,860–2,930 r/min; floor, wall, or roof installation options |
| Noise and maintenance | JK No. 4 noise ≤86 dB(A) in open space; compact structure, low local resistance, and convenient maintenance |
| Use conditions | For non-coal mines and tunnel/underground engineering; confirm airflow, pressure, duct, and local electrical requirements before ordering |
Installation, electrical connection, grounding, inspection, and operation must follow the manufacturer manual, mine ventilation plan, and applicable local rules. Confirm explosion-protection requirements where relevant. Isolate power before maintenance and keep the fan and duct system clear of obstructions.
For a project quotation, send the application, site country, working dimensions, operating conditions, required capacity or duty, power supply, applicable mine rules, delivery target, and documentation requirements. Zongda Mining can then confirm the configuration, technical documents, export packing, shipping plan, commissioning scope, and spare-parts recommendation.
Add a verified project case before publication. Use project type, customer requirement, selected configuration, support provided, and a short result description. Do not publish customer names, mine locations, production figures, or performance improvements without approval.
What is an underground mining ventilation fan used for?
It supplies or extracts air through a ducted ventilation circuit serving underground headings, tunnels, and work areas.
What is the difference between airflow and pressure?
Airflow is the volume of air delivered. Pressure is the force available to overcome duct and circuit resistance. Both values are needed for selection.
Can the fan be used in a long heading?
Possibly, but the duct length, diameter, bends, leakage, and required face airflow must be checked against the fan curve and installation plan.
What should be included in a quotation request?
Provide the target airflow, pressure or duct resistance, duct layout, power supply, installation space, operating environment, destination, and required documents.
