Characterization of Rock Temperature Changeability in the Halemba Coal Mine Deposit (the Upper Silesian Coal Basin)

摘要

The main geological element influencing the temperature changeability within the Halemba Mine area is Klodnica fault, which divides this area into two parts with different rock temperatures. The area lies to the north of the fault (the upthrow) and is characterized by a higher temperature than in the area located to the south (the downthrow). The same trend is shown in the case of geothermal gradient and geothermal heat flow. The reason for the higher rock temperatures in the upthrow of the Klodnica fault might be the occurrence of many smaller accompanying faults which could cause the better transport of radiogenic heat from the deeper parts of the rock mass towards the surface and in consequence make the rock temperature higher in the area of Halemba I. The rock temperature rises in the north-east direction. The distribution of temperature in the area of the Halemba Mine is an element of a regional trend, not only the local changeability.
