A digital model of the South Moravian Lignite Coalfield in the Bzenec area, and its visualization
 Kajzar, Vlastimil ; Staněk, F.
A digital model of the South Moravian Lignite Coalfield in the Bzenec area, and its visualization. In this contribution, the methodological procedures for modeling and assessing of the lignite deposit in the Bzenec area of the Czech part of the Vienna Basin (the South Moravian Lignite Coalfield) are presented. There is a territory where Dubňany seam (Pannonian F) occurs. All necessary primary data together with data about uniformly reassessed balanced seam thicknesses in about 230 boreholes were collected into a deposit database. This database was further studied in order to create the deposit model. The seam in the studied area is split into three coal benches (altogether 5 horizons). The basic deposit model is a so-called geological model, which describes the structural character of the deposit and defines the spatial positions of the coal seams. On the basis of the geological model so-called balanced models, i.e. variant models according to the coal quality, are created.

Observation of phases of surface changes above exploited deposits of sedimentary type
 Kajzar, Vlastimil ; Doležalová, Hana ; Staš, Lubomír ; Souček, Kamil ; Šimkovičová, Jarmila
Due to exploitation of coal and other raw materials of sedimentary type there happen many surface changes connected mostly with subsidence, shifts and deformations of the area of interest. Such processes happen mainly in the overlaying strata of exploited coalface. Size and directions of these movements and deformations depend generally on many factors, primarily on geo-mechanical properties of overlaying strata and general technique of exploitation of the deposit. One of the ways of surface observation of time spatial changes is the usage of modern methods for precise determination of changing position of geo-features. Among these methods we rank GPS surveying and usage of methods for gaining data from aerial photogrammetry. Subsequent processing, analysis and modelling of output data by means of modern GIS software offer an efficient source of information for subsequent work and decisions.
