Zusammenfassung:	The utility model belongs to the technical field of mine engineering equipment, and particularly relates to a vibration screening device for coal mine engineering, which comprises a main body support,a main body base is installed on one side of the main body support, a rotating shaft is installed above the main body support, and a damping main body is installed above the damping support. A vibrating screen is installed above the main body support, a first screen cloth layer is installed on the inner side of the vibrating screen, a second screen cloth layer is installed on the inner side of the vibrating screen, when large coal granularity needs to be screened, the second screen cloth layer is moved to one side of the first screen cloth layer to be attached, and the size of the screened coal granularity is the aperture size of the first screen cloth layer. When the small coal particle size needs to be screened, the second screen cloth layer is moved to the clamping groove position of the first screen cloth lay
