For designing precisely the reinforcement of mine gate and reinforcing underground structures in general, knowing stress and deformation states in the rock massive in the immediate vicinity of these mine works as precisely as possible is absolutely decisive. In order to verify the rock mass stress state and its changes induced by longwall mining, the monitoring of rock mass stress changing in connection with the mine out of the coal seam No. 501, longwall face No. II/501/C in the Mine Staszic-Wujek, Poland, was suggested. The aim of the contractual research was the realisation and interpretation of the rock stress state monitoring using the CCBO (Compact Conical ended Borehole Overcoring method) and CCBM (Compact Conical ended Borehole Monitoring method) probes in the forefield of mentioned longwall face within geotechnical station. To verify stress monitoring, the survey of the state of the longwall gate was carried out using a pulse 3D scanner. The purpose was to capture deformation changes ahead of the advancing longwall face, specifically, at five stages in the ± 20 m section on each side from the installed geotechnical station.

Structural mapping of exploration geotechnical boreholes walls within 2nd phase – Decline
Waclawik, Petr; Schuchová, Kristýna; Kukutsch, Radovan; Georgiou, Lucie
2022 - English
Structural-geological analysis, i.e. fracturing assessment of the walls of geotechnical boreholes (CIS38 and CIS39) within the projected Decline in lithium exploratory area was carried out on the basis of optical (OPTV) and acoustic televiewer (HiRAT) records evaluation. HiRAT and OPTV probes are part of the Robertson Geologging logging equipment. The apparatus has an electric winch with a four core logging cable, which transmits the data recorded by the probes via a data logger to a computer. The spatial data obtained from interpretation of the geotechnical boreholes records were structurally analysed. The submitted research report comprehensively summarises the findings obtained from the structural mapping of geotechnical boreholes. On the basis measured data the rock mass quality evaluation of boreholes walls were additionally done. The complex data have been allowed very precise analysis of rock mass structural conditions, which are necessary for design of opening mine working.

RTIN-based strategies for local mesh refinement
Kolcun, Alexej; Sysala, Stanislav
2021 - English
Longest-edge bisection algorithms are often used for local mesh refinements within the finite element method in 2D. In this paper, we discuss and describe their conforming variant. A particular attention is devoted to the so-called Right-Triangulated Irregular Network (RTIN) based on isosceles right triangles and its tranformation to more general domains. We suggest to combine RTIN with a balanced quadrant tree (QuadTree) decomposition. This combination does not produce hanging nodes within the mesh refinements and could be extended to tetrahedral meshes in 3D.

Resuscitation of landscape painting by research of landscape changes
Havlíček, M.; Slach, T.; Skokanová, H.; Halas, Petr; Kallabová, Eva; Koutecký, T.; Šebesta, J.
2021 - English
An analysis of selected landscape paintings shows that only a third of them are located directly on a hiking trail, bike path or nature trail. In the case of other landscape paintings, it is possible to make other, hitherto neglected parts of the territory more attractive to tourists by locating the places of the painter's shots, which may lead to their desired deconcentration from the places that are frequently visited by tourists.

New opportunities for geotourism development at geoarcheological site Holedná Hill (Brno, Czech Republic)
Kubalíková, Lucie; Kirchner, Karel; Kuda, František
2021 - English
Special Interest Tourism is often seen as a form of ‘alternative’, ‘ethical’ or ‘environmentally responsible’ tourism and it occurs when the tourists’ motivation and decision-making are primarily determined by a particular special interest with a focus either on activities and/or destinations and settings and search for novel experiences (Novotná et al. 2019). \nOne of the types of sites are called geocultural sites (Reynard and Giusti 2018). Geoarcheological sites can be considered a type of geocultural sites and can be defined as sites where geological aspects are accompanied and closely related to archaeological issues. \nThe Holedná Hill (Brno, Czech Republic) can be considered an example of such geoarcheological site. It is important from the Earth-science point of view and it includes specific archaeological issues that are closely related to the geodiversity. This paper briefly sums the natural and cultural values of Holedná Hill and based on the geomorphosite assessment and SWOT analysis.\n Keywords: geoheritage; cultural heritage; environmental education; geocultural site; recreation Available on request at various institutes of the ASCR

Anthropogenic relief transformations - their knowledge and evaluation with regard to the uniqueness and cultural identity of regions
Kirchner, Karel; Kubalíková, Lucie; Kuda, František; Havlíček, M.
2020 - English
Within the development of new regional geography, the role of human geographic research in the study of regions is emphasized. Regional uniqueness, a consciousness of belonging to a particular However, physical geography disciplines, e.g. geomorphology, can also contribute to the knowledge of these aspects with regard to the definition of regions. Currently, within the framework of geomorphology, attention is paid to the diversity of anthropogenic landforms. The knowledge and evaluation of these anthropogenic landforms, which are an important part of the historical elements of the landscape and are also referred to as cultural artefacts of the landscape, enables to supplement the cultural-historical values of the region and to specify the cultural identity of the region. On the example of sites - Staré Hradisko and Hostýn - we will present the specifics of secondary geodiversity with respect to the cultural identity of the sites.

Geological paths – their use for the regional geography teaching
Kubalíková, Lucie; Drápela, E.; Bajer, A.; Zapletalová, D.; Balková, M.; Zágoršek, K.; Kirchner, Karel; Kuda, František; Roštínský, Pavel
2020 - English
Geological paths (geopaths, geotrails) represent a type of educational paths that connect sites, which are interesting from the Earth-sciences point of view. These sites (e.g. outcrops, old quarries, historical buildings built of local stone or viewpoints) often represent the links between geodiversity and other phenomena within a region (which is in accordance with a holistic approach to geotourism). Thus, they can give complex information not only about the abiotic nature but also about biodiversity, history or culture of the region, usually through narrative. Suitable interpretation of geodiversity and its relationships to the biodiversity and cultural heritage allows to identify regional specifics, it helps to find the mutual connections between particular phenomena within the region and it supports the holistic perception of a given region. The contribution presents an example from the Brno city where the urban geopath can be used for teaching regional geography of Brno and its surroundings.

Developing urban geotourism in Brno (Czech Republic)
Kubalíková, Lucie; Kirchner, Karel; Bajer, A.; Balková, M.; Kuda, František
2020 - English
The term “urban geotourism” is defined as tourism based on the places within the city boundary (both in the form of built heritage - monuments, buildings, statues - and rock outcrops) that is related to geological concepts and features. As a first step for the development of urban geotourism it is necessary to identify and inventory the geotourist resources, which should take into account both natural (geological, geomorphological, hydrological or palaeontological, and ecological aspects related to geodiversity), and cultural aspects related to geodiversity (e.g. monuments, building stone, geo-toponyms, anthropogenic landforms). Based on the classification of geotourist sites, selected examples from Brno (Czech Republic) are given, supplemented by geotourist and geo-educational activities. In the conclusion, the advantages of urban geotourism are summarized and its importance for the protection of abiotic nature and sustainable management of valuable sites is suggested.\n\n Keywords: geoheritage; cultural heritage; geoeducation; geocultural sites; geoarchaeological sites; anthropogenic landforms Available on request at various institutes of the ASCR

Residual ancient landscape segments in Carpathians of Moravian-Slovak borderland
Kolejka, Jaromír; Nováková, Eva; Kirchner, Karel
2020 - English
The Moravian Carpathians border region is a large area located in the east of the Czech Republic. Historically, most of the time it was a peripheral border area between the Czech state and Hungary. The well-preserved segments of pre-industrial landscape were inventoried here. They have such arrangement of land use, which originated in the period before the main wave of the industrial revolution in the Czech lands (i.e. before 1850), and has been preserved until present. A total of 182 segments of pre-industrial landscape were identified. Spatial analysis of their location in the area shows that the highest concentration of segments is near the international border (50% up to 10 km from the border), in dissected highland relief (52%), but often in the foothills between 300-500 meters above sea level (51%). Due to their location and appearance, they can represent interesting geotourist objects in the border area.
