Separation Of Gangue From Coal Based On Histogram Thresholding
نویسندگان
چکیده
Coal gangue is residual abandoned coal, produced after the pre-processing steps of mining. It is an amalgam of several unwanted substances. It is important to separate coal gangue from lump coal before fed to thermal power plants. In this paper, investigation on the fundamental characteristics of coal images and gangue images with digital image processing technology is proposed. The system determines the image feature of coal and gangue, particularly their gray scale values by using traditional threshold segmentation. By analyzing the characteristics of the image, the system identifies the gangue. The outcome indicated that the comparison of coal images and gangue images could successfully achieve the real-time automatic separation of gangue.
