The paper describes the presence of fibres in respirable coal dust in high rank coal mines in Lower Silesia. The amount of fibres in dust particles is about 1.5% (by count). Testing by the incineration test, the lack of atomic number contrast in electron back-scattering imaging in SEM and X-ray microanalysis allow the fibres to be identified as coal. The authors suggest the possible role of coal fibres in the increased fibrogenic activity of the dusts in coal mines in Lower Silesia.

UI MeSH Term Description Entries
D008855 Microscopy, Electron, Scanning Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
