The Blanka tunnel, geological hazadrs and problems during boring
Sedláček, Václav ; Král, Jan (advisor) ; Lešner, Jeroným (referee)
The Blanka tunnel has two boring sections: Brusnice tunnel and Královská obora tunnel. Both tunnels were boring in difficult geologycal conditions, but the geology conditions of these tunnels are not same. Also they had not the same hazards during boring. There was used a spectrum of different technical works with hazard reduction purpose and safety process of boring. There were three serious accidents, wnich everyone made a creater on the surface, but they have not the same causes. This text has a task to describe a geological survey before and during the boring of both tunnels. How other reasons affected the process of boring? How the tunnels were bored? What events preceded the everyone of three major failure? This text does not deal with economical things of boring and effects of specific personal influence on the process of boring. Key words Tunnel, excavation, Blanka, Brusnice, Letná, Stromovka park, Vltava river, underground water, geology, ordovik, New Austrian Tunnelling method, pilot tunnel, calotte, bench, bottom, arche, bolt, lining, grouting, collapse of ceiling, failure, tube, shale, quarzite, soil, loess, ballast, clay

Enviromental Analysis of Slate Quarries in the Nízký Jeseník (The Czech Republic)
Rozkopalová, Pavla ; Skalický, Milan (advisor) ; Jan, Jan (referee)
This dissertation applies its mind to the evaluation of five selected localities caused by slate mining in the area of the Low Jeseník, namely at point-blank range the Kružberk water reservoir and is based on the lichenological research and on the Czech Hydrometeorological Institute data. Two lacalities, 1 and 2 are located in the west side of the dam, the locality 3 is in the east side and the localities 4 and 5 are located to the south from the dam.
From 2015 to 2016, during the ongoing research, there were determined 23 the most commonly ocuring tereristic lichen species. To the found vulnerable species belong, for example, Cladonia glauca or Cladonia ciliata. In the locality 3 the most occuring family Cladoniceae is mainly represented by Cladonia ciliata, Cladonia rangiferina and Cladonia arbuscula.
Based on the results it was discovered that lichen species coming from the Cladoniceae family are the most frequently spread on the upper part of the localities, on the top of the slate slag heaps; but the slopes are prefered by sessile species. The slope posts are too extreme because of their enormous inclination and exposition. The tree storey was determined too together with frequency of woody plants incidence on the grounds of localities shielding. Full-grown trees expanded from the surrounding forest were especially found at the slag heap bases. Larix decidua was mostly observed, Betula pendula colonized slopes. On the bases of The Czech Hydrometeorological Institute data was the Kružberk dam area assessed relatively clear because it is the area protected against pollution and and is considered to be a fresh water resource. Air pollution made by NO2, SO2 and MP10 showed good results with low improving level from 2014 to 2015.
There is made a suggestion to have the minimal management because there was not seen any negative human or animal influence to the lichen diversity and natural evolution of association has been going on. Large frequency of Cladoniceae was monitored in the locality 3 and so this locality is suggested for long-term monitoring of environment with chemical-physical methods and monitoring lichen diversity.
The author developed her photo suplement and used here her own illustrations to easy determine the most common species occuring on the stone quarry. This appendix can be found at the end of the dissertation.

Sediment disintegration due to air compressed by capillarity: overlooked erosion mechanism
Vaculíková, Jana ; Bruthans, Jiří (advisor) ; Kostkanová, Vladislava (referee)
Cílem této práce bylo orientačně otestovat, do jaké míry je rozpad díky vzduchu stlačovanému kapilární vodou nasávanou do sedimentu (kapilárně-pneumatický rozpad, KP rozpad) významným procesem při erozi různých sedimentů, jako jsou písky až slabě cementované pískovce, spraše, jíly, jílovce a případně i jílovité půdy. Dílčím cílem bylo především vytvořit a na několika vybraných materiálech otestovat jednoduchou metodiku, prokazující, zda sediment podlehne KP rozpadu, dále vypočítat destrukční tlak daný KP rozpadem v pórech sedimentu a porovnat ho s tahovou pevností materiálu a konečně posoudit vliv mineralogie a porosity sedimentů na KP rozpad. Pro odlišení KP rozpadu od jiných destrukčních procesů jsem zvolila pozorování rozpadu dvojic vzorků, kdy jeden byl saturován za běžného atmosférického tlaku vzduchu a druhý ve vakuu. Tato metoda je schopná odlišit KP působení od jiných erozních procesů a zároveň je přiměřeně rychlá a vhodná pro různé sedimenty a zeminy. Pozorování potvrzuje, že KP působení je schopno rozložit různé sedimenty a zeminy na jemné částice, jedná se o velmi důležitý proces rozpadu, který probíhá i ve stojaté vodě, může být iniciátorem pipingu a měl by být proto intenzivně studován. Srovnání vypočtených hodnot pórového tlaku s tahovou pevností ukázala, že vypočtené pórové tlaky...

Current Trends in Unconventional Oil and Natural Gas Production with Focus on the U.S.
Prášek, Jakub ; Vošta, Milan (advisor) ; Vlčková, Jana (referee)
The thesis deals with the current trends and development of the unconventional oil and natural gas production. The main aim is to evaluate and analyze the global development of unconventional production and the influence of its growth in the last decade on the global economy and the given markets. In addition, not only the pros, but also the risks and limitations of unconventional production, are examined, e.g. economic and environmental issues. The final part focuses on the United States and the local shale boom. Based on the analysis of American unconventional production, the future of these sources is predicted. At the end of the thesis the effects of shale boom on the U.S. economy are explored as well, focusing mainly on the U.S. trade balance.

Current and future trends in world trade and extraction of shale gas
Brückler, Jaroslav ; Müller, David (advisor) ; Trojanová, Kamila (referee)
This thesis look into extraction and trade of shale gas. The aim of this thesis is to simply explain to the readers the basic principles of trade with the shale gas and to present its possibilities in extraction and its use. I also describe all side affects, that are related to the extraction and trade with the shale gas such as, impact on the environment or the price of the natural gas. The thesis provides the reader with the basic knowledge of processing of the shale gas, possibilities of its extraction and trade and of its positive or negative impacts on world trade with the natural gas.

Nekonvenční způsoby produkce ropy a zemního plynu a jejich vliv na mezinárodní obchod
Černý, Martin ; Štěrbová, Ludmila (advisor) ; Baláž, Peter (referee)
The growing world population accompanied by an increase in GDP is effectively raising the demand for energy. One of the options are unconventional means of oil and gas, originating mainly from shales and oil sands. The goal of this thesis is to introduce the reader to unconventional means and their influence on international business. After a short introduction and definition an analysis of the situation in the U.S. follows, where the recent years have brought an increase in production from unconventional sources. The positive influence on the economy, employment and energetic security will be mentioned same as possible impacts on the environment. Furthermore the paper provides an analysis of the potential of repeating the U.S. shale revolution in other countries, with special focus on the EU. The success of unconventional sources opens the possibility of new trade routes, influence on the trade balance and the potential of influencing the whole gas market. However, it will also have an impact on current oil and gas producers. Considering the close bond between energetic security and politics, the thesis closes with an analysis of influences on the economy and politics of both -- current oil and gas producers and countries, which might be directly and indirectly affected by changes in the oil and gas market.
