Background
Ventilation is a serious problem in mine production, and if ventilation cannot be effectively performed, life health and safety of underground constructors can be endangered, and further construction progress is affected, so that mine production efficiency is affected. However, the underground tunnel is more, the situation is complex, the targeted ventilation is not facilitated, the targeted ventilation of a certain area is improved, and the ventilation door is required to be arranged for ensuring the passing of personnel and vehicles.
In mine production construction, the air door is one of the most main ventilation devices, and is arranged on a wind shielding wall so as to keep the passage and transportation of the tunnel. In order to ensure the stability of the wind flow of the mine ventilation system and the normal running of the mine car and the safe passing of personnel in each transportation roadway, air doors are usually required to be arranged in the roadways. Most of the domestic air doors at present have shortcomings in structure and scheme, and the disadvantages reduce the applicability of the air doors
The currently commonly used air door is almost unpowered, the air door can be opened by manual work, and quite large force is needed to open the air door (the larger the pressure difference at two sides of the air door is, the larger the door opening force is), so that manual physical consumption is increased.
The lever type air door has the advantages of complex mechanical structure, difficult processing, large installation occupation and poor safety performance.
Because the section shape of the tunnel is mostly elliptical, the air door is also an integrated straight plate type, if the air door is designed according to the section shape, the air door cannot be completely opened and cannot be clung to the tunnel wall. Can only be designed as a rectangle or square.
The wind door is arranged on the wind shielding wall, so that some large mining equipment cannot conveniently pass through the wind shielding wall due to the size, and the utilization rate of the section area of the roadway is reduced.
