Abstract: With the development of intelligent technology and equipment in coal mine, it gets a lot of results in the intelligent ventilation system. However, there are many deficiencies in the catastrophic ventilation system. However, there are few studies on the management of ventilation system after disasters. As one of the means to prevent and control fresh air side disasters, the research on technology and equipment of ventilation system should be strengthened. Through the study of air counter technology in 3105 fully mechanized caving face of a coal mine, the wind control technology of main inlet roadway disaster and working face air inlet drift disaster is obtained. According to the wind control technology, the technical requirements of hardware such as air door, wind window, wind measurement, environmental acquisition sensor, voice broadcast and disaster avoidance command are analyzed, which provides technical and hardware equipment support for the ventilation system of similar mine working face.
