Abstract This paper presents the results of studies on gas sorption performed by means of the gravimetric method. The tests were performed on two coal samples of different metamorphism degrees, came from two regions of Upper Silesian Coal Basin, Poland. The changes in sorption capacity of coals were measured in the pressure range from 0.1 MPa to 17 MPa and in temperatures ranging from 291K to 333K. Coal of a lower coalification degree was a better methane sorbent. Changes in sorption capacity of tested coals were linearly dependent on the temperature. The increase in temperature of 10K reduces the Langmuir sorption of about 0.7-0.8 [cm3/g]. Such increase of temperature causes a nonlinear increase of the Langmuir pressure (b-1). These results showed that the rise of rock temperature, caused by geothermal gradient, can induce a significant increase of equilibrium pressure of methane in coal seam. An increase of coal seam temperature may cause an increase of gas and coal outburst risk in a coal mine.

Abstract Kokowska-Pawłowska, M. and Nowak, J. 2013. Phosphorus minerals in tonstein; coal seam 405 at Sośnica- Makoszowy coal mine, Upper Silesia, southern Poland. Acta Geologica Polonica, 63 (2), 271-281. Warszawa. The paper presents results of research on tonstein, which constitutes an interburden in coal seam 405 at the Sośnica- Makoszowy coal mine, Makoszowy field (mining level 600 m), Upper Silesia, southern Poland. The mineral and chemical compositions of the tonstein differ from the typical compositions described earlier for tonsteins from Upper Silesia Coal Basin area. Additionally, minerals present in the tonsteins include kaolinite, quartz, kaolinitised biotite and feldspars. The presence of the phosphatic minerals apatite and goyazite has been recognized. The presence of gorceixite and crandallite is also possible. The contents of CaO (5.66 wt%) and P2O5 (6.2 wt%) are remarkably high. Analysis of selected trace elements demonstrated high contents of Sr (4937 ppm) and Ba (4300 ppm), related to the phosphatic minerals. On the basis of mineral composition the tonstein has been identified as a crystalline tonstein, transitional to a multiplied one.
