Article
Full-text available
The assessment of the possibility of using incinerated municipal waste, which is classified as non-hazardous, is a priority of the European zero waste strategy. The aim of this work was to identify the properties of slag and ash to develop a simple, targeted way of using post-process waste. The material was analyzed by microscopic methods in terms...

The analysis of phenomena related to gas transport in hard coal is important with regard to the energetic use of coal bed methane (CBM), the reduction of greenhouse gas emissions to the atmosphere (CO2) and the prevention of natural hazards such as methane hazards and gas and rock outbursts. This article presents issues concerning the feasibility a...
Article
Full-text available
Coals from the south-western part of the Upper Silesian Coal Basin have a strong outburst susceptibility. The objective of this study was to identify the influence of coalification degree on methane sorption and micro scale strength properties of 24 coals from Jastrzębie Zdrój. Coal samples showed a reflectance Ro between 0.98 and 1.25%. Sorption m...
Article
Full-text available
the paper presents the results of a study of methane adsorption on coal samples with various degrees of metamorphism, coming from the Polish and Czech parts of the upper Silesian Coal Basin (uSCB). the range of coalification of the samples was from bituminous with vitrinite reflectance Ro equal to about 0.5% to para-anthracite coals with Ro equal t...
Article
Full-text available
Selection of the optimal properties of coal as a natural sorbent, both as a sample collected from a seam or of the coal seam itself, requires various parameters to be determined and may not be based on the knowledge of metamorphism degree only. In order to improve the predictions of sorption capacity and the kinetics, analyses of correlation and mu...
Article
Full-text available
Near-fault coal displays some specific structural and textural features. As the distance to the fault diminishes, one can observe ever stronger, gradual degradation of coal, demonstrated by the emergence of structural distortions exogenic in their origin, visible under a microscope. The process of gradual degradation of coal—manifested by the appea...
Article
The evaluation of threats connected with the presence of methane in coal seams is based on our knowledge of the total content of this gas in coal. The most important parameter determining the potential of coal seams to accumulate methane is the sorption capacity of coal a. It is heavily influenced by the degree of coalification of the coal substanc...
Article
Five medium metamorphosed coals from the south-western part of the Upper Silesian Coal Basin were subjected to sorp-tion and petrographic studies to det. the variability of poros-ity, degree of coalification, content of main maceral groups and sorption capacity with increasing seam depth. Obtained decrease of the sorption capacity of coal and incre...
Article
Full-text available
Basic knowledge of the characteristics of cop-per-bearing rock such as dolomite is essential to locate those areas of the deposit which have different structural and textural properties. Those regions can be important in terms of the assessment of the possibilities of gas accumulating in them as well as in terms of gasogeodynamic hazard. To better...
Article
Full-text available
As regards the exploitation of hard coal seams, the near-fault zones and faults themselves are considered to be particularly dangerous areas, which is due to a high probability of the occurrence of gasogeodynamic phenomena. Tectonic dislocations running across a seam have a destructive impact on coal. Degradation of the coal structure, particularly...
Article
Full-text available
The article presents the results of microscopic analyses of shear bands of carbonate rocks subjected to triaxial compression. Strength tests were performed in axisymmetric loading conditions, at various confining pressures and strain rates. The layout and nature of phenomena occurring in shear bands at various strain rate loading conditions were an...
Article
This paper presents the results of comprehensive petrographic-stereological study performed on the coal samples from five hard coal deposits in Upper Silesia. These samples derive from specific spaces in the deposits, where tectonic processes led to fault occurrence. The detailed analysis of the petrographic composition of samples was aimed at the...
Article
Full-text available
The petrographic features of hard coal coming from the Upper Silesian Coal Basin (USCB) coal seams are very different. Additionally some differences among them are associated with the influence of external tectonic factors on these formations. The coal with specific, “altered” structure appears very often near tectonic disturbances. This “altered”...
Article
Full-text available
Lower Carboniferous rocks of Western Pomerania are interesting in terms of petrographic composition containing fragments of volcanic rock (called volcaniclasts). This unique volcanic material is abundant in Lower Carboniferous sandstones. However, the volcanic clasts are present in all types of Lower Carboniferous sedimentary rocks of this zone. Th...
