description The utility model relates to the technical field of coal mine underground explosion suppression, and discloses a needling type high-pressure airflow driving mechanism which comprises an induction device and a needling device which are fixedly connected, and the end, away from the induction device, of the needling device is connected with a gas injection device in a sliding mode. The gas injection device comprises a high-pressure cavity and a sealing spherical membrane fixed to the end, close to the needling device, of the high-pressure cavity in a sealed mode, and a *-shaped crack is formed in the middle of the sealing spherical membrane. According to the scheme, the sensing device is used for sensing explosive shock waves in air, converting the explosive shock waves into mechanical energy and driving the needling mechanism to move towards the direction close to the gas injection device in a mode of being connected with the needling device until the needling mechanism makes contact with and punctures the cent
