Spontaneous vegetation succession in mined peatlands
KONVALINKOVÁ, Petra
Spontaneous vegetation succession in mined peatlands in the Czech Republic was studied using the space-for-time substitution approach. The study focused on the variability of vegetation in traditionally mined (block-cut) and industrially mined (milled) peatlands. The influences of age, abiotic site factors, as well as landscape factors were analysed. The thesis summarizes also the state of current knowledge on various groups of organisms (plant, algae, fungi, and animals) in the extracted peatlands in the Czech Republic. The recomendations for the ecological restoration of mined peatlands are given.
Industrial production and its influence on the environment in the Czech Republic - general trends
MALENICKÁ, Klára
The final bachelor thesis deals with the issues of industrial production and its influence on the environment in the Czech Republic. It consists of three main chapters {--} extractive industry, energy industry and manufacturing industry. These chapters focus on the policies applied to the given sector of these industries, their development after 1989, their structure, allocation and environmental impact. General environmental impacts of the industrial production are illustrated with specific examples. These are further illustrated by charts, graphs, pictures and cartographical outputs.
The Exploitation and Utilization of Energetic Raw Materials in the World
MATĚJKA, Petr
This Diploma theses is dealing with the creation of general current list of reserves, production, consumption and trade of each energy raw material with a view to fossil fuel. The introduction of my work is applied to general reflection reflecting present state of fuel issue. The following chapters are talking about the aims of my work, the literature analysis and the methodology. After the introductory part there are particular chapters talking about crude oil, gas and coal. All these parts of work are dividend into the subchapters containing general introduction that describes each energy raw material. This work brings the inttegrated current data of mined fuel material organized into the synoptic tables. These tables are completed with schematic graphs. The assembled tables determine the list of the biggest international producers, consumers, shippers and importers of each strategic energy commodity. The conclusion of study belongs to the summary of determined aims of work and the outline of importance of fuels in the present-day world.
History of mining uranium deposit in Příbram
SASKOVÁ, Klára
The region I´ve chosen for my diploma thesis is situated on the border of Poberounská and Czech-Moravian system of geomorphological unit Bohemian Massif. It used to be one of the richest uranium mining district of Příbram region, and it is characterized by geological structure of central-Bohemian plutonium within the geological complex Bohemian Massif. On the contiguity of it there is found vast hydrothermal uranium deposit. This deposit is divided into 9 panels ? Třebsko, Kamenná, Lešetice, Brod, Jeruzalém, Háje, Svatá Hora, Bytíz, Skalka and Obořiště, which belong to the Příbram district. The town Příbram is famous for its long-standing mining tradition not only of polymetalic but above all of uranium ores. This tradition achieved the great success of world standards in the second half of the 20th century. There was revealed a lot of hydrothermal dikes containing requested uranite (black blende, nasturan) after the Second World War. This raw material was heading to Soviet Union. Uranium mining works initiated its epoch in 1949 and regular mining activities finished by the closing of the last shaft in 1991. In all the period of time there was mined 50200, 8 tones of uranium ore. Uranium deposit in Příbram can also take pride in the deepest shaft No. 16 with the depth of 1838, 4 m which is the shaft No. 16. In connection with the mining there was formed the life of local people and also the life of people from all Czechoslovakia who were setting off to seek a living there. Today all the shafts are closed and deluged in a natural way. In certain area of the deposit has been built cavern gas reservoir. No other mining will be possible in the future. The state enterprise Diamo realizes revitalization works on former mining panels and monitors the value of surrounding environment.
The changes in the localization of the extractive industry and the political consequences.
Novosadová, Monika ; Vošta, Milan (advisor) ; Kašpar, Václav (referee)
The bachelor thesis analyzes the global changes in the territorial structure of the extraction of the mineral resources, especially the energy resources and less some precious metals and diamonds and related political consequences. This bachelor thesis describes also the importance of these resources for human society and their deposits. There are also outlined possible future development of the extraction of these resources. The first chapter illustrates general characteristic of the extractive industry. It introduces the ranking of the extractive industry, main mining regions and the biggest producers of some minerals. The second chapter closely presents energy resources, i. e. mining of energy resources, their deposits, their usage and possible future developments. The third chapter focuses on the mineral resources, i. e. their extraction, deposits, usage and possible future trends. The fourth chapter introduces the political consequences related with global changes in the territorial structure of the extraction of the mineral resources.
Economic aspects of reclamation of brown coal quarry near the town Most
Štemberová, Daniela ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
The master thesis deals with reclamation of brown coal quarries from different perspectives. It focuses on the various options of reclamation of quarries. It evaluates the economic benefits and costs, integration into the way of rehabilitation needs and the future use of this reclamation. It defines a way how to optimise the use of devastated land. This thesis is focused on the reclamation of region Most specifically on the brown coal quarry called Ležáky - Most. It considers if hydrologic variant of reclamation for the quarry is the best. It describes other possibilities of reclamation that have been considered. The master thesis introduces the reasons for the selection of the hydrologic reclamation. It reviews the complexity of the hydrologic reclamation of the quarry Ležáky -- Most, its effect on the environment, social sphere and the further societal use. The main objective is to analyze the total effectiveness of quarry Ležáky - Most, if the mining was profitable taking into account all its costs and revenues.

Těžba polymetalických konkrecí z hlubokomořského dna jako alternativa ke kontinentálním zdrojům nerostných surovin
Linhartová, Ivana ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
Práce se zabývá problematikou těžby polymetalických konkrecí z hlubokomořského dna, která se dnes jeví jako alternativa ke kontinentálním zdrojům nerostných surovin. V současné době se zásoby využívaných kontinentálních zdrojů nerostných surovin velmi rychle blíží k úplnému vyčerpání, cena surovin na světových burzách rychle roste, a to je velkou zátěží hlavně pro státy, které určité typy nerostných surovin na svém území vůbec netěží a musí je dovážet, což je právě případ ČR. Práce se zaměřuje hlavně na analýzu těžby vybraných rud a to jak ke vztahu k ČR, tak i ve vztahu ke zbytku světa. Dále se snaží nahlédnout do pozadí problematiky samotné těžby hlubokomořských konkrecí, která i přes její současnou aktuálonost není obecně příliš rozšířená. Poslední část práce analyzuje "pro" a "proti" zahájení těžby z oceánského dna.
