Separating coal and gangue using three-dimensional

2017-12-10  Gangue minerals accounts for between 15% and 20% of raw coal in China (Qian et al., 2007). Indeed, as coal production has increased, so has gangue generation; by the end of 2009, the total amount of gangue produced added up to 5.0 × 10 9 t, encompassing 40% of the total Chinese solid waste (Miao and Qian, 2009).

煤矸双能X射线图像多维度分析识别方法研究

The results show that the identification rate of mixed gangue of rich coal is 98.89%, that of mixed gangue of charred coal is 100%, and that of mixed gangue of gas coal is 99.44%. Combined multiple features of multiple images for multi-dimensional analysis, the method finds that R-value image features and high-energy image features have the best discrimination degree to coal and gangue.
