The door structure of an Mine Automatic Doors is the foundation for its basic functions, mainly consisting of a door frame and door leaves. The door frame is typically made of high-strength steel, such as I-beams and channel steel, welded into a robust frame structure.
These steel sections possess excellent compressive and bending resistance, capable of withstanding the weight of the door itself and the complex pressure environment within the tunnel, ensuring no deformation or damage during long-term use, thus providing reliable support for the stable operation of the air door.
Application of Mine Doors
Man doors & airlocks: Allow personnel passage while maintaining ventilation integrity.
Surface mines: Secure entrances against unauthorized access and elements.
Stoppings
These are walls that are used to turn the airflow in a certain direction. These structures can be both permanent and temporary. They are manufactured using fire retardant and resistant materials since the risk of fires is high in the case of underground mines.
Man doors & air locks
The former, as is evident from the name is mounted in stoppings for providing passage to miners. Air locks comprise a couple of doors for regulation air pressure while workers pass through man doors.
Brattices
These partitions installed between columns of mines are made of wood or cloth, to control and direct the entry of breathable air and exiting of toxic gases.
Overcasts
These are utilized for guiding air across intake and return passages if the air is needed to cross but without coming into contact with either intake or return air. Overcasts are usually made of prefabricated steel and concrete blocks.
Booster fans
These are responsible for adjusting airflow, which they can increase and direct to a particular section. A few countries have restrictions as these might lead to undesirable recirculation of air. Booster fans have to be incorporated in such a way that they don’t interfere with the airflow, which is why regulators are used to keep airflow to desired levels.
