Hydraulic Mine Door For Deep Mining

The hydraulic automatic air door for deep mining is an intelligent ventilation control device designed for underground roadways with high wind pressure and large cross-sections.Adopting hydraulic power drive and pressure-free balance structure, this door can adapt to extreme environments with roadway negative pressure of 0-3000Pa, and is suitable for scenarios requiring frequent opening and closing of air doors such as driving roadways and high gas outburst areas.

The hydraulic automatic air door for deep mining is equipped with a three-mode control system of manual/auto/remote. In case of pressure loss, it can be opened through an emergency manual device to meet emergency escape needs. In addition, the door surface is treated with anti-corrosion spraying, allowing it to be used stably for a long time in environments ranging from -30°C to 40°C.
