Method and device for identifying coal and gangue under complex working conditions in fully mechanized caving process and medium

The invention provides a method and a device for identifying coal and gangue under complex working conditions in a fully mechanized caving process and a medium, the method for identifying coal and gangue under complex working conditions in the fully mechanized caving process comprises the following steps: arranging a conductive surface on a conveying belt, so that all fallen minerals pass through the conductive surface when being conveyed; an image recognition device is arranged above the conductive surface, and minerals passing through the conductive surface are recognized through the image recognition device; current recognition devices are arranged on the two sides of the conductive face, and current generated when the minerals pass through the conductive face is obtained through the current recognition devices and compared with set current; according to the comparison result of the current and the set current and the identification result of the image identification device, the proportions of coal and gan
