Air door control system used for mine and application method thereof

The invention provides an air door control system used for a mine and an application method thereof. The system comprises an air door, one side of the air door is hinged to an air door frame, a vent hole is formed in the air door, a door-window through which the vent hole can be closed and opened is slidably arranged on the air door in the vertical direction, a door-opening balancing weight is suspended at the upwind side of the air door through a lifting rope, the pressure to which the door-opening balancing weight is subjected is smaller than wind push force to which the air door is subjected when the vent hole is closed and larger than wind push force to which the air door is subjected when the vent hole is open, the other end of the lifting rope bypasses a fist pulley and is fixed to the air door, and a door-window driving mechanism is further arranged at the upwind side of the air door. The air door control system aims to solve the problems that it is greatly difficult to open existing air doors in case air cylinders or power pipelines of the air doors have problems, disastrous consequences may be caused if a mine accident occurs or quick evacuation is required, and heavy potential safety hazards exist. The invention belongs to the technical field of mine ventilation.
