The effect of toxicity and othet parameters of substrate on plant growth in post mining sites.
Zadinová, Radka ; Frouz, Jan (advisor) ; Kočí, Vladimír (referee)
Surface mining of coal in the country leaves a lot of damage. This type of mining is characterized by the creation of large external dumps. The dumps often contain substrates with toxic substances or substances which become toxic after reaction with air. These substrates are toxic to plants and edaphon. This work is intended to show what properties of substrates are important for phytotoxicity. The location of research was selected including 3 different kinds of substrates, terrain unevenness and a lagoon in the middle. Coordinate grid has been created on the selected location. At each point a test was conducted with plant Sinapis alba and biomass was extracted from a naturally growing vegetation. Further, at the points substrates were collected and values of pH, conductivity and arsenic were measured. Test with plant Sinapis alba was repeated in the laboratory conditions as well. On site GPS coordinates were measured for the mathematical model created in ArcGIS. Experiment has shown the importance of the type of substrate and the geologic description, and then the association between dejection, value of pH and conductivity. Conductivity and pH levels also correlate with the germination Sinapis alba and biomass of naturally growing vegetation.

The effect of artificial weathering on overburden properties
Zadinová, Radka ; Frouz, Jan (advisor) ; Bartuška, Martin (referee)
Surface mining of coal cause massive changes of landscape. Dumps, heaps and tailings created vast areas in post mining landscape. Soil formation is influenced by the weathering process. Sample-the most common substrates have been subject of accelerated weathering. Samples were watered by distilled water, left to soak in, then froze, thaw and dried. This cycle was repeated twenty times. Before the experiment and after experiment pH, conductivity, organic matter loss on ignition, grain size and water absorption were measured. Before and after the experiment were tested for toxicity to plants using yellow mustard seeds (Sinapis alba). Accelerated weathering showed the possible development of weathering spoil substrates over time namely shift of pH towards neutral value, and increase in water holding capacity, despite of this no changes in plant toxicity in toxic substrates were found.

Changes of the area around the Ore Mountain Railway during the period of industrialization
Monhartová, Monika ; Matoušek, Václav (advisor) ; Sekyrková, Milada (referee)
This diploma thesis discusses the changes of the cultural landscape and its inhabitants around the Ore Mountain Railway during the period of industrialization. The goal of a thesis is to describe the changes during the period of industrialization and the influence of newly build Ore Mountain Railway. The Ore Mountain Railway was a significant international transport link furthermore existence of railway had direct influence on the development of small villages in the vicinity. This thesis focuses on villages directly influenced by this railway in the period of industrialization. The first part is devoted to explanation of fundamental terms and description of region. Furthermore, there is a historical description of the region before the period of industrialization. In the next part is stated specific major development of the cultural landscape related to the growth of traffic and industry. In addition, there also describe social changes in the period of industrialization. The major focus of thesis is on the village Hrob. This village is used as an example for explanation of the influence of the Ore Mountain Railway to its region. In the last part is briefly described current state of the Ore Mountain Railway in these days.

Settlement Desertion in Consequence of Opencast Brown Coal Mining in the Most District and Chomutov District - the Example of the ČSA Mine
Malá, Michaela ; Kučera, Zdeněk (advisor) ; Ženka, Jan (referee)
- Settlement Desertion in Consequence of Opencast Brown Coal Mining in the Most District and Chomutov District - the Example of the ČSA Mine The thesis deals with the settlement desertion due to the open cast mining of brown coal. The area of interest is the ČSA Mine which lies on the border of the Most and Chomutov districts. The first part is devoted to the changes in the settlement structure of the both districts in the 20th century, with the emphasis placed on the settlement desertion. The concentration of the settlement was affected not only by the destruction of residential structures, but also by the post-war transfer of Czech Germans and the process of urbanization. Population changes in the Chomutov and Most districts are processed also graphically. The other part of this work is focused on the ČSA quarry itself and the settlement destroyed as a result of its expansion. The regional ecological mining limits, set by the government in 1991, protect the villages of Horní Jiřetín and Černice against the advancing liquidation process. The issue of breaking those limits is processed using qualitative research - an analysis of interviews with representatives of neighboring municipalities, civic associations and mining companies. The analysis of the interviews is accompanied by the scenarios of...

Bachelor's thesis describes the concept of sustainable development in theory and practice, practice focuses on the region of Sokolov and its specifics. The goal is to determine how the Sokolov region through the strategy of sustainable development is facing the impacts of the mining of brown coal. It analyzes in particular the impact of mining activities in the region and using the concept of sustainable development is looking for possible solutions and recommendations for its development. Main benefits of this work is a case study in which, through a questionnaire survey collected the views of local actors in different areas of sustainable development. The regional analysis and research findings underlying final recommendations for the future development of the region.
