Influence of mining on environment in respect to ecotoxicology
Kociánová, Sabina ; Vávrová, Milada (referee) ; Zlámalová Gargošová, Helena (advisor)
This thesis deals with an influence of mining on environment from the point of view of ecotoxicology. First focus in the thesis is on overall impact of coal mining on environment. The thesis is especially closely focusing on mine water, its formation and negative influence on aquatic ecosystem. In this connection the thesis mentions examples of ecotoxicological evaluation, so called acidic mining water. The thesis also mentions legislative scope that is related to the issues about protecting environment against impact from coal mining and subject dedicated to restoration of affected areas.

AFTER THE EXTRACTION Atlas of the Ostrava-Karviná coal basin problems and an alternative settlement options
Vicanová, Nela ; Eristavi, Irakli (referee) ; Mitášová, Monika (advisor)
The thesis deals with the research of landscape issues related to coal mining in the Karviná region. The landscape of the Ostrava-Karviná coal basin, which has suffered anthropogenic devastation caused by the extraction of the raw material, faces problems related to the instability of the terrain. Crucial for the research and the project are the data obtained, which determine the thematic location and the investigative and an analytical framework of the project. Using the key data, key questions and risks are formulated. The research extends into geological and landscape themes, determining a re-evaluation of architectural practice in such unstable conditions. The first aim of the thesis is to obtain data for the visualization of stabilized and unstable areas of the landscape after mining based on interviews with experts and map data. Furthermore, this information will be analyzed and interpreted in order to define the area of interest and suggest what the future of the unstable area might be. Finally, the third objective is to propose a new, utopian layer to the existing landscape.

Framing of the Turów Case in Regional Media
Pištorová, Barbora ; Nečas, Vlastimil (advisor) ; Křeček, Jan (referee)
The aim of the thesis is to analyze the framing of coal mining in the Turów case in news coverage in regional Czech daily newspapers, using a qualitative content analysis of media outputs. The thesis consists of four main parts. In the theoretical part, the thesis summarizes agenda-setting theory, defines the concept of framing, as well as a brief typology and approaches to identifying frames, and describes framing in news reporting. It also offers an overview of the studies focused on the framing of environmental topics by the news media and specifically on coal mining. This is followed by a brief history and development of the Turów case and a methodological section that defines the selected and analyzed media content, but also identifies the risks of this research. Grounded theory and two basic types of coding were chosen to perform the qualitative analysis: open and axial. With their help, the framing used in news coverage of coal mining in the regional media was described, and the identified frames and attributes of the coal mining were subsequently compared with previously conducted studies. The work thus offers an overview of how the media framed coal mining in the Turów case and offers insight into this debate.

Atlas of Land Cover Changes in the Lake Most Area
Kryndlerová, Anna ; Čábelka, Miroslav (advisor) ; Lysák, Jakub (referee)
The aim of this bachelor thesis is to create atlas of landscape changes in Lake Most area. The partial goals include evaluation of landscape development within historical context, visualization of land cover structure in 1842, 1938, 1952, 1987 and 2021, and creatation of additional maps, graphs and tables to illustrate land cover development for the whole monitored period. The theoretical part explains the basic concepts related to landscape and land cover and describes the base data layers and methods for analysing and evaluating landscape changes. Furthermore, the rules, concepts and methods of thematic cartography are described. This is followed by the physical-geographical and socio-economic characteristics of Lake Most area and its historical development in regards to coal mining and reclamation. In the practical part, a suitable atlas creation method is proposed based on the acquired knowledge. The key part of the map creation process is working with historical base data layers. The output of the work is a printed atlas of landscape changes in the area of Lake Most, created in ArcGIS and InDesign softwares. Keywords: Land cover change, Visualisation, GIS, Lake Most, Atlas, Coal mining, Reclamation

Indicators of ecosystem recovery after heavy disturbances
Hermová, Markéta ; Frouz, Jan (advisor) ; Hardekopf, David (referee)
Minerals mining have huge impacts on the coutrryside and fundamentally change its character. The restoration of the habitats can be done basically in two ways. The mine can be either abandoned and left to natural succession or recultivated. In order to decide how to proceed on actual site, we have to carefully consider all the surroundings and set the objective we want to reach. Naturally, we are not able to monitor all the characteristics present in given locality and their changes. Therefore it is highly convenient to use a set of indicators, which can cover majority of these characteristics and will sensitively respond to development of the whole ecosystem. I decided to use three types of indicators in this study. These are physiochemical environment, ecosystem production and diversity. Through these indicators I have analysed the restoration possibilities of degraded ecosystems in localities used for coal mining in former times. I have chosen coal because it is an important commodity in Czech Republic.

Soil water regime of reclaimed and unreclaimed post mining heaps
Cejpek, Jiří ; Frouz, Jan (advisor) ; Moldan, Bedřich (referee) ; Tesař, Miroslav (referee)
This PhD thesis compares the water regime of reclaimed and unreclaimed spoil heaps after brown coal mining, with special regard to the development of hydrological properties of soils, which are determinant for the movement and retention of water in the soil. The basic influence on the supply of soil water has the technology of pouring the spoil heaps and aging, which co-regulates the development of vegetation. During the development of soil's spoil heaps increases field water capacity and water retention, but also increases the wilting point. These changes are related to the accumulation of organic matter in the soil and the degradation of claystones to particle size of physical clay. The development of the ability of the spoil heaps soils to bind water is greater in reclaimed areas, where the upper organomineral horizon develops more rapidly, but there is also a wilting point and water consumption. On unreclaimed area, the soil substrate develops more slowly. Overall, the differences in water regime between reclaimed and unreclaimed areas are small.
