It is impossible to realize automatic control or remote control of the damper window between the +267m yard and the channel connection lane of the working face in the North second mining area of Yannan Coal Mine. There are some problems such as inconvenient pedestrian traffic, untimely ventilation network for disaster control, small width of air regulation and high intensity of air regulation, which greatly affect the reliability of the ventilation system and threaten the safe and efficient production of the underground. In view of this problem, the relevant theories and applications of the damper window control system are studied, and the traditional plug-in window is changed into the louver window which adjusts the air area by rotating motion. In addition, the flow of personnel or vehicles passing through the damper and the control system of the damper window are designed by using micro-control technology combined with the actual situation. Through practical use, under the operation of this system, the use function of the damper and window meet the requirements of underground safety production, remote control is reliable, stable operation, and can realize the adjustment of large width of the air volume, which greatly reduces the input of human resources and improves the intelligent level of Yannan Coal mine.
