  • Patent number: 12036581
    Abstract: Tandem methods and devices for separating coal and gangue based on visible light and an X-ray are provided. The method comprises: determining, based on a visible light image, an image feature set and a target region of coal gangue; recognizing the coal gangue and removing large gangue in the coal gangue; performing imaging on the coal gangue after the large gangue is removed; extracting a target image and determining a gray scale value of the target image; obtaining samples of coal and gangue of different granularity levels by performing sampling; establishing a database and obtaining a separation threshold of coal and gangue of each granularity level of the current mining area; forming a mapping set and storing the database in a storage space; and obtaining a gray scale value of subsequent coal gangue, importing the gray scale value of the subsequent coal gangue into the mapping set to subsequently separate coal and gangue.
