Abstract

Aiming at the problems of small separation range and low separation rate in the intelligent separation of coal and gangue, a threshold separation method based on dual-energy X-ray technology is proposed. Low-energy original image, use ratio method to obtain R-value image, integrate R-value image and low-energy image information to fit the R-L curve of coal and gangue, count characteristic values and draw sample distribution maps, calculate the sorting threshold of coal and gangue, and realize coal and the sorting of gangue. The experimental results show that the threshold sorting algorithm is more effective in improving large-size materials than the traditional R-value recognition algorithm and R-L curve fitting algorithm, and the recognition rate of 150-300mm materials is as high as 96.99% and 92.32%.
