Abstract
The use of the scanning electron microscope (sem) to characterize coal mine dust has been possible because of two circumstances. First, the imaging process of the sem allows multiple signals (secondary and back-scattered electrons, x-ray emission, etc.) to be viewed. Second, the use of a computer to analyze the signals and perform statistical tests on the results. The parameters described are size, shape, chemical composition, mass distributions, and particle thickness. Although the system is intended for particular systems, those of agglomerates are handled by special aspects of the computer programs.
