Methodology for determining the provenance of raw materials for the production of historical lime mortars
Martinec, Petr; Ščučka, Jiří
2022 - Czech
The methodology was developed in the years 2018-2021 as part of the solution of the project Historical landscape on the border of Silesia and Moravia financed by the Ministry of Culture of the Czech Republic (project No. DG18P02OVV017, NAKI II programme). The methodology is based on the long-term experience of prof. Petr Martinec, Ph.D. and Jiří Ščučka, Ph.D. in the field of geomaterial and building material analyses, which are carried out at the Institute of Geonics of the Academy of Sciences of the Czech Republic in cooperation with experts from the fields of archaeology and monument care. The methodology includes a comprehensive procedure for identifying potential original sources of raw materials used for the production of the main material components of historical lime mortars – aggregate and binder. The methodology also includes: principles of sampling mortars and comparative rocks or soils in situ, procedures for laboratory material analysis of aggregates, binders and rocks to determine relevant comparative parameters, and the main information sources that can be used when searching for sources of raw materials.\n Metodika byla vypracována v letech 2018-2021 v rámci řešení projektu NAKI II č. DG18P02OVV017 s názvem Historická krajina na pomezí Slezska a Moravy financovaného Ministerstvem kultury ČR. Metodika vychází z dlouholetých zkušeností prof. Ing. Petra Martince, CSc. a doc. Ing. Jiřího Ščučky, Ph.D. v oblasti geomateriálových a stavebně-materiálových analýz, které jsou prováděny v Ústavu geoniky AV ČR, v. v. i. ve spolupráci s odborníky z oborů archeologie a památkové péče. Metodika obsahuje komplexní postup při identifikaci potenciálních původních zdrojů surovin použitých pro výrobu hlavních materiálových komponent historických vápenných malt – kameniva a pojiva. Součástí metodiky jsou zásady odběru vzorků malt a srovnávacích horninových či zeminových vzorků in situ, postupy laboratorní materiálové analýzy kameniva, pojiva a hornin pro určení rozhodných srovnávacích parametrů, a také hlavní informační zdroje, z nichž lze při hledání surovinových zdrojů vycházet.

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.

Convergence measurement of CSM Sever vent shaft and mining work No. 292291 on 3rd floor in connection with the mining of the face No. 292 200/2 using 3D terrestrial laser scanner technology
Kajzar, Vlastimil; Koníček, Petr
2022 - Czech
On the basis of a contract, the Institute of Geonics of the CAS realized repeated convergence measurement of selected part of the mining works in order to capture spatio-temporal and dynamic changes in connection with the mining of longwall face No. 292 200/2. The subject of the use of terrestrial laser scanning technology was to capture the current spatial situation of of the approximately 200 m long section of corridor No. 29229. Furthermore, the spatial state of vent pit on the 3rd floor of the CSM Sever mine and its adjacent surroundings was also a subject of interest. The project here continuously follows on from the previous long-term monitoring carried out as part of contractual research with OKD, a. s. in 2020-2021 - Convergence measurement of CSM Sever vent shaft and adjacent surroundings on 3rd floor using 3D terrestrial laser scanner technology.\n Na základě smlouvy o dílo realizoval Ústav geoniky AV ČR, v.v.i. opakované zaměření konvergencí definovaných částí vybraných důlních děl za účelem zachycení časoprostorových a dynamických změn v souvislosti s dobývání porubu 292 200/2. Předmětem nasazení technologie pozemního laserového skenování bylo zachycení aktuální prostorové situace přibližně 200 m dlouhého úseku chodby 292291. Dále byla předmětem zájmu prostorová situace 3. patra výdušné jámy ČSM Sever a jejího přilehlého okolí. Projekt zde kontinuálně navazuje na předchozí dlouhodobý monitoring realizovaný v rámci smluvního výzkumu s OKD, a. s. v letech 2020-2021 - Měření konvergencí pomocí 3D pozemního laserového skenování výdušné jámy ČSM Sever a přilehlého okolí na 3. patře.

Evaluation of the risks of the terrain surface influencing from the point of view of geomechanical changes of the rock massif due to the flooding of the mining environment of the Ostrava and Petřvald sub-basins of the OKR by mine water - Interim report III
Kajzar, Vlastimil
2022 - Czech
Attenuation of the remaining, still active mines of OKD company will mean the end of the primary reason for pumping mine water from mines, which is to ensure the safety of work and operation underground. At the same time, this eliminates the need to maintain the currently determined level of mine water in the already attenuated part of the Ostrava-Karviná district (OKR), i.e. in the Ostrava (ODP) and Petřvald (PDP) parts of the OKR, which are now ensured by the Jeremenko (ODP) and Žofie (PDP) water shafts. After the end of all activities in the OKR underground, the process of flooding of the abandoned mine could be started. The aim of this work is to determine the possible risks caused by geomechanical and rheological changes in the rock massif disturbed by mining activity and, above all, the associated possible risks of affecting the earth's surface.\n Útlum zbylých, dosud činných dolů OKD, a.s. bude znamenat zánik primárního důvodu čerpání důlních vod z dolů, kterým je zajištění bezpečnosti práce a provozu v podzemí. Zároveň se tím eliminuje potřeba udržování v současnosti stanovené hladiny důlních vod v již utlumené části ostravsko-karvinského revíru (OKR), tedy v ostravské (ODP) a petřvaldské (PDP) části OKR, kterou nyní zajišťují vodní jámy Jeremenko (ODP) a Žofie (PDP). Po ukončení veškerých aktivit v podzemí OKR by tak mohl být spuštěn proces zatápění opuštěných důlních prostor. Cílem této práce je stanovit možná rizika způsobená geomechanickými a reologickými změnami v horninovém masívu, porušeném hornickou činností a především s tím spojená možná rizika ovlivnění zemského povrchu.

Viewpoint geosites and their potential for geoeducation and geotourism
Kubalíková, Lucie; Kirchner, Karel; Kuda, František
2022 - English
Viewpoint geosites are locations which allow observation of the surrounding landscape and comprehension of geodiversity (or Earth history recorded in rocks, structures and landforms) visible from this locality. The sites themselves don‘t have to be attractive from the Earth-sciences point of view, so they may be both natural (e.g. rock outcrops, mountain tops) and man-made objects (e.g. watchtowers, view terraces). These sites represent a very important resource for geotourism and geoeducation as they allow understand landscape, its history and relationships between its components. In this paper, we present examples of viewpoints from Podyjí National Park (both natural and man-made structures) that allow to observe geodiversity of the area. For an effective management and rational use of these specific and important sites, it is necessary to identify their characteristics and potential, so the guidelines for inventorying and method for assessment their potential are proposed. These procedures can contribute to the development of geotourist and geoeducational activities and above all, they enable better understanding of geodiversity’s position within landscape and justify its conservation and sustainable use.

Landscape photography in the research of landscape change
Skokanová, H.; Halas, Petr; Koutecký, T.; Kallabová, Eva; Havlíček, M.; Slach, T.
2022 - English
The paper presents partial results of “entering” landscape photography, which can be considered as a complementary method for the research of landscape changes. Unlike the usual assessment of landscape changes using cartographic and other archival sources, old landscape photographs can contribute to the deeper knowledge of the local specifics of the examined places or supplement the conventional procedures. Thanks to the ongoing project, supported by the Technology Agency of the Czech Republic (TL02000222), we documented changes in photographic shots of various landscapes in the 20th century. We also added information about environment, vegetation, and geography and photo documentation of the details of the researched shot. This creates a comprehensive output for each old landscape photograph. Such processed photographs have been presented at exhibitions in museums and galleries. Furthermore, they will be available to municipalities and public at a web page created as a tool to support public recreation. Here we present some examples from the Bohemian-Moravian Highlands. They show four types of landscape changes: 1) afforestation and overgrowth bywoody vegetation, 2) changes in the agricultural landscape, 3) loss of the grazing landscape, and 4) changes related to watercourses.\n
