摘要

摘要: 针对常见选煤方法存在成本高、自然资源消耗大、环境污染严重，X射线选煤法对于不同厚度的煤和矸石容易出现识别错误等问题，设计了一种基于X射线和光纤传感器的煤与矸石分选系统。该系统首先利用X射线扫描获取煤和矸石X射线图像，经处理后得到图像灰度值；然后采用光纤传感器检测煤和矸石的厚度；最后综合灰度值和厚度确定煤矸识别阈值，实现煤和矸石的分选。实验结果表明，该系统利用煤矸识别阈值能有效识别煤和矸石。

Abstract: In view of problems of high cost, high consumption of natural resources and serious environmental pollution existed in common coal preparation methods and X-ray coal preparation method was easy to occur identification errors for different thickness of coal and gangue, a separation system of coal and gangue based on X-ray and optical fiber sensor was designed. Firstly, X-ray images of coal and gangue are obtained by X-ray scanning, which are processed to get gray value of the images. Then thickness of coal and gangue are measured by optical fiber sensor. Finally, identification threshold value of coal and gangue is determined by integrating gray value and thickness, so as to realize separation of coal and gangue. The experimental result shows that the system can identify coal and gangue effectively through the identification threshold value of coal and gangue.
