Negative pressure air duct, also known as negative pressure suction device, is a device that uses airflow to generate negative pressure and extracts a

Mining fan is a special type of fan used in coal mines, which has a special structure and function and is suitable for various application scenarios s

As a high-energy ventilation equipment, negative pressure air ducts play an important role in energy conservation and emission reduction.

There is indeed a specific relationship between the size and power of the air duct, which mainly stems from the working principle and actual needs of

In some construction processes nowadays, for the sake of ventilation and breathability, it is necessary to use certain ventilation equipment, and the

Due to the polluted air below the mine, low oxygen content, and high dust content, the mine air duct needs to have good ventilation efficiency, and th

When replacing the coal mine ventilation duct fabric, it is not allowed to stop the local ventilation fan at will. If it is necessary to stop the mach

Ventilation: The mining air duct can transport fresh air from the wellhead to the working area underground, while discharging the exhaust gas undergro

The working principle of mining air ducts is mainly based on the pressure difference of gases and the basic principles of fluid mechanics. In the mine

Mining anchor cable is an engineering structure widely used in mining sites such as coal mines and gold mines, mainly used to support tunnels, roadway

Anchor agent: This is a material used to fix solid road surfaces for reinforcement, and it can achieve its fixing effect in various ways.

Anchor agent is a commonly used adhesive in construction engineering, mainly used for the interaction between steel bars and concrete. Its main compon
