Lateral development of coalification in the Czech part of the Upper Silesian Coal Basin and its connection with gas deposits

Popis výsledku v původním jazyce

The degree of coalification is an essential parameter influencing the quality of coal reserves. Modelling of the development of this parameter in the Czech part of the Upper Silesian Coal Basin (Carboniferous, Mississippian to Pennsylvanian ? Lower Namurian to Westphalian A) revealed the distribution of coalification within the basin in all its stratal units. The grade of coalification was found in principle to be similar but its intensity in general decreases upwards into the hanging wall. Because of different areal extents of individual stratal units the degree of coalification is demonstrated on the oldest and areally most extensive unit ? the Petřkovice Member. The studies and their results presented in this paper are based on more than 29,000 analyses of the moisture- and ash-free volatile matter (Vdaf) in coal samples from surface and underground boreholes drilled in the years 1946 ? 2000. Three zones of enhanced coalification were distinguished: the Ostrava-Příbor Zone, the Rožn
