Crosshole seismic techniques can be used to gain a large amount of information about the properties of the rock mass between two or more boreholes. The bulk of this thesis is concerned with two crosshole seismic processing techniques and their application to real data. The first part of this thesis describes the application of traveltime and amplitude tomographic processing in the monitoring of a simulated EOR project. Two physical models were made, designed to simulate 'pre-flood' and 'post-flood' stages in an EOR project. The results of the tomography work indicate that it is beneficial to perform amplitude tomographic processing of cross-well data, as a complement to traveltime inversion, because of the different response of velocity and absorption to changes in liquid/gas saturations for real reservoir rocks. The velocity tomograms image the flood zone quite accurately. Amplitude tomography shows the flood zone as an area of higher absorption but does not image its boundaries as precisely, because multi-pathing and diffraction effects are not accounted for by the ray-based techniques used. Part two is concerned with the crosshole seismic reflection technique, using data acquired from a site in northern England. The processing of these data is complex and includes deconvolution, wavefield separation and migration to a depth section. The two surveys fail to pin-point accurately the position of a large fault; the disappointing results, compared to earlier work in Yorkshire, are attributed to poorer generation of compressional body waves in harder Coal Measures strata. The final part of this thesis describes the results from a pilot seismic reflection test over the Tertiary igneous centre on the Isle of Skye, Scotland. The results indicate that the base of a large granite body consists of interlayered granites and basic rocks between 2.1 and 2.4km below mean sea level.

From small exploration companies to multi-national mining houses all at some point in the project lifetime embark on evaluation studies where the most value-generating method of extracting the ore is investigated. Early phases in exploration projects will have the need for an order-of-magnitude estimation as to the scale of the potential operation, and advanced projects will have detailed mine and financial plans to guide them to execution. In both instances this thesis provides a method of optimising the mining rate to deliver the highest possible value to the mining company whilst considering the possible risks from changes in the market. This can be compared to the value the country gains from the exploitation of its natural resources to find a mutually beneficial solution.

This diploma thesis deals with the issue of public participation in deciding activities of reclamation. I chose former quarry Silvester near Dolni Rychnov as my research area. This area was transformed into eighteen-holes golf grounds and wood grounds with sport and relax stuff during reclamation work. This thesis consist of theoretical, methodological and empirical section. Theoretical section introduce basic concept of recultivation, law regulating recultivation, conservation, restoration ecology as scientic field and last but not least Sokolov region as region with long tradition of recultivation. The Methodological part describes methods of practical research, which is essential part of this thesis. The Empirical section introduce results of my research. Key words: reclamation, opencast coal-mining, restauration ekology, nature conservation, reclamation project, expert interview, questionnaire
