摘要
介绍了煤表面的微结构特点和煤表面的各种检测方法及其特点。经过比较,选用原子力显微镜(AFM)对煤体表面进行了三维检测,利用CSPM -2000 Imager软件对扫描得到的图像进行了颗粒度分析,并提出了一种计算煤表面突出颗粒与孔隙所占比例的方法。结论表明AFM在煤体微结构检测过程中具有独特的优势。
The features of coal's microstructure, the each method for detecting coal's microstructure and its characteristics are introduced. After comparing, the surface patterns of coal are scanned. With CSPM-2000 imager software by atomic force microscopy (AFM), the images are analyzed in graininess. A method for calculating the percentage of coal surface's extrusive granules and pore space is proposed. The results demonstrate the AFM has particular advantag es in the course of detection on coal's microstructure.
