What Are The Types Of Mining Air Ducts

There are various types of mining air ducts, which can be divided into the following categories based on their different characteristics and uses:
Classified by mechanical properties:
Rigid air duct: such as hard gate air duct, usually made of 2-3mm thick iron plate, has advantages such as durability, long service life, and diverse ventilation. However, it is high in cost, easy to corrode, heavy in weight, difficult to disassemble and transport, and difficult to use in curved tunnels. In recent years, fiberglass ducts have gradually been applied due to their lightweight, resistance to strong acid and alkali corrosion, and low friction resistance coefficient, but the cost is also relatively high.
Flexible air ducts: such as canvas air ducts, adhesive air ducts, synthetic leather air ducts, etc. Flexible air ducts have advantages such as light weight, easy disassembly and transportation, and fewer joints, but they have low strength, are prone to damage, and have a short service time. They are mainly used in forced ventilation situations.
Classification by coating material:
Rubber coated fabric positive pressure air duct
Plastic coated fabric positive pressure air duct
Rubber coated fabric positive pressure air duct
Classified by purpose:
Centrifugal mine air duct: It is a widely used type of mine air duct.
Axial flow mine air duct: suitable for the transportation of large amounts of gas, with high air volume but low pressure.
Other types of mine air ducts, such as portable mine fans, explosion-proof fans, industrial centrifugal fans, etc., can play an important role in dealing with different special needs in work environments.
In addition, mining air ducts also have the characteristics of flame retardancy and electrical resistance, so their flame retardancy is called mining flame retardant air ducts. In order to meet different usage environments and needs, the design and manufacturing of mining air ducts have been constantly innovating and improving to ensure their safe and efficient application in mining engineering.
