description The embodiment of the invention provides an airflow adjusting assembly and a control method and device thereof. The airflow adjusting assembly comprises a first air door, a second air door and a first adjusting valve; the first air door is arranged in a main delivery channel, the second air door is arranged in a coal wall, grooves matched with the width of a belt are formed in the first air door and/or the second air door, after the first air door in an opened state and the second air door in an opened state abut against each other, the belt penetrates through the grooves, the first air door blocks an airflow channel formed from the top of the belt to the top of the main delivery channel, and the second air door blocks an airflow channel formed from the top of the coal wall to the bottom of the belt; the first adjusting valve controls opening and closing of the first air door and the second air door. After a fire occurs in a belt roadway, the first air door and the second air door can be controlled to be open
