	Srovnání předpokládaných a měřených poklesů v hornické krajině Doležalová, Hana There was a repeated GPS surveying done on stabilized points of an observation station that was built in a mining area near Karviná. The GPS surveying was used to document the displays of mine subsidence on the surface above exploited coalfaces. A comparison of the modelled supposed subsidence and the subsidence measured by GPS was done and it has shown on some discrepancies. Presumably the main cause may be seen in the difficult geological and geo-mechanical situation that is not generally included in the modelling of the supposed mine subsidence. Detailed record
	Změny horninového masívu v blízkosti okraje poklesové kotliny Doležalová, Hana Repeated geodetic and geophysical surveying near the margin of a creating subsidence depression has shown on a fluctuation of heights of levelled points and on significant rock massif changes. The possible cause of these changes may be found not only in progressive stress-deformational changes due to undermining but also in the changing regime of the groundwater. Confrontation of the levelled height changes with the height of the groundwater level shows that the regime of the groundwater may be a substantial cause of surface height changes. Also the resistivity anomalies found by geophysical measurements can be caused by change of hydro-geological regime. Detailed record
