The invention discloses a push-pull type air door for mining. The invention comprises a driving motor, a second pulley, a gear plate and teeth. When the air door is used normally, the operation of the driving motor drives the sliding door to slide on the inner wall of a U-shaped box. Since the gear plate rotates in opposite directions to the driven gear, two groups of sliding doors can be moved away from or towards each other, thus saving space occupied by opening the doors, and the structure is simple and safe to use. The invention comprises a first pulley, a second belt strip, a threaded shaft and a limiting shaft. When a power outage occurs, the threaded shaft can be rotated by shaking the handle to move the threaded shaft up and down. The movement of the threaded shaft drives the door body to move up and down, thus preventing the air door from being unable to be opened when a power outage occurs, and improving the use effect of the push-pull type air door for mining.
