Studium chemickych a fyzikalnich vlastnosti sloji ceske casti hornoslezske panve a priprava atlasu jejich mikropetrografickych typu a chemicko-technologickych vlastnosti

In the grant project, GAČR No. 105/01/0325, termed in English "Chemical and Physical Properties of Seams of the Czech Part of the Upper Silesian Basin from the Point of View of the Long-Term Outlook for the Base of Raw Materials in the Czech Republic", it was decided to execute two new tasks: to produce the Petrographic Atlas of Coal Macerals and the Atlas of the Chemical-Technological Properties of Coals (both dealing with the Upper Silesian Coal Basin). For executing the first task, nearly 8000 photographs of the coal polished sections (mainly from the Upper Silesian Coal Basin) from a unique archive were digitised. Now we are completing the set of images transformed to a database containing the description of the photographs. Thus the access to the photographs and their next processing will be easy. Simultaneously, the publishing of a representative book comprising a selection of photographs and accompanying text is under discussion. Some of the photographs will be fed as study material to the Internet via web pages. The Atlas of the Chemical-Technological Properties of Coals of the Czech Part of the Upper Silesian Basin, which is just being prepared, is designed to map the spatial distribution of selected chemical-technological parameters, in particular the litho-stratigraphic units of the Productive Carboniferous in the Czech part of the Upper Silesian Basin. For this purpose, the content of volatile matter (Vdaf), swelling index (SI), contraction (a), dilatation (b), combustion heat (Qsdaf), ash (Ad), vitriniL reflectance (R0) and the contents of vitrinite, liptinite and inertinite in coal matter were considered. The Atlas will show the spatial distribution of the parameters in a set of 80 maps accompanied by a brief text describing the development or particular parameters shown in the maps of the Atlas.
