Geological setting of bituminous coals and anthracite coals in the Rybnik Coal District, Poland
- Silesian Technical Univ., Gliwice (Poland). Institute of Applied Geology
For Poland, the Rybnik Coal District is the most important prospective source for all the technological types of bituminous coals and also for anthracite coals. Thus, the area may be a proving ground for mining coal with ecological restrictions in areas degraded by many years of industrial activity. Geological conditions in this part of the Upper Silesian Coal Basin are characterized by strong differentiation of tectonics from Namurian A to Westphalian B formations. Moreover, the quality of coal varies, and the intensity of the occurrence of natural hazards, mainly gas hazards, is different. This paper presents an attempt at regional division of the Rybnik Coal District according to the degree of carbonification, petrographic composition, and chemical-technological properties of coals; inconsequence, some possibilities for their rational utilization and for the prognostication of ecological effects have also been indicated. The degree of carbonification expressed by the content of volatiles is V{sup daf} = 3.5 to 49.4%; expressed by the mean reflectance, it is Rm{sub oil} = 0.62 to 4.89%. The carbonification indices exhibit various usability. The index V{sup daf} characterizes better low- and medium-rank bituminous coals, while the Rm{sub oil} index characterizes high-rank bituminous coals, particularly anthracites.
