Czech - Polish Conference on the Coal Basins Geology /7./
Kožušníková, Alena
The 7th Czech - Polish conference on the coal basins geology represents a traditional meeting of specialists, mainly from CR and Poland. Within the frame of the conference there are presented papers concerned with wide problems - coal basins characterization, sedimentary progression and structural geology of the coal basins, stratigraphy, petrography of rocks and coal, physical and chemical properties of coal and rocks, palynology, creation of digital models of the coal basins.

Fluorescenční mikroskopie a analýza obrazu mikroporušení hornin
Ščučka, Jiří ; Kožušníková, Alena ; Obara, B.
The paper presents analytical methods used at the Institute of Geonics ASCR for quantitative analyses of micro-fracturing arising in rocks under various loading conditions in laboratory. Primarily optical fluorescence microscopy and image analysis of sections saturated by fluorescence dye are used to these purposes. The full-automatic image analysis method for determination of intensity and distribution of micro-cracks in rock specimens is presented in the paper as well as the formerly used manually procedure.

Measurement of coke porosity by image analysis methods
Ščučka, Jiří ; Kožušníková, Alena
An effective method for visualization and quantitative analysis of coke porosity is presented in the paper. The method is based on image processing and analysis combined with fluorescence microscopy of impregnated coloured preparations and enables the determination of percentage portion of pores in the coke, mean pore-size, mean cell-wall thickness and their distribution.
