| description | The invention provides a continuous mining face dust control device which is applied to a continuous mining machine and comprises a negative pressure injection spraying device and a spraying nozzle, the spraying nozzle is arranged on the side, facing a cutting roller, of a machine body and is provided with a spraying direction right facing a dust production position of the cutting roller, and the spraying nozzle is used for spraying to form a mist curtain for preventing dust from diffusing. A negative pressure area with an air inlet can be formed in the negative pressure injection spraying device so as to absorb dust-containing airflow near the cutting roller through negative pressure; the dust control device is located on the side, away from the cutting roller, of the machine body, one end of the dust control device communicates with an air supply air cylinder at the top end of the continuous mining face roadway, the other end of the dust control device faces the continuous mining machine and forms an axial |
