Recognition of Coal and Gangue Based on X-Ray

Abstract

In this paper,a recognition method of coal and gangue based on x-ray is studied. With the different density , the coal and gangue on a belt can be detected by x-ray. After penetrated by x-ray, with the acquisition of ray signal and image analysis, the gangue can be accurately distinguished from the coal. As a result, the quality of coal is improved. Proved by experiment, this method is more efficient and accurate than other methods.
