This report describes the work carried out in the second year of the public contract Geological and geotechnical characterisation of the rock environment – PVP Bukov II. The\ncharacterisation and descriptive works are directly related to the excavation of the premises for the future underground laboratory. These include in particular: geological and geotechnical documentation of the faces and walls of the workings, petrographic, mineralogical and structural geological documentation, hydrogeological characterisation of the environment, as well as determination of the physical and mechanical properties of the rock mass in situ and in the laboratory, geophysical characterisation and monitoring of the seismic effects of blasting and hydrogeological monitoring. An important part of this report is preparation of the classification system used to describe the rock mass. The report also includes a brief overview of the work planned for the third year of the project.

Hydraulic and mechanical-physical properties of rocks: Experimental determination and interpretation of results of granite testing
Sosna, Karel
This work is focused on the groundwater flow and transport of contaminants in the environment of granitic rocks. Mainly adjective and dispersive types of transport of contaminants are discussed in this work. Transport of contaminants by diffusion is mentioned only marginally in relation to porosity of rock matrix. The main aim of this work was to characterize hydraulic and mechanical-physical parameters of the granite. Partial objectives were to verify the sealing function of the laboratory grout mixture in fractured granite blocks, to characterize the porosity and hydraulic conductivity of the granite matrix at laboratory scale, to find connection between boreholes in situ and to establish a link between the structure of rocks and velocities of seismic waves. Four bentonite and cement mixtures in different weight ratios have been selected as a grout mixture. Suitable injection mixture was selected based on the results of hydraulic conductivity coefficient, and other aspects, such as volumetric stability. The granite blocks were partially grouted by using of the selected grout mixture. Hydraulic conductivity and porosity of the granite rock matrix from the Panské Dubenky test site was tested at three laboratory samples. Hydraulic conductivity was determined with different constant hydraulic...

Final Report of the Project „Data Acquisition from the Deep Horizons of the Rožná Mine“ presents the results of the study of rock mass properties with respect to the presence of a significant tectonic zone. The study focused on the change of properties in the vicinity of the so-called first zone of the Rožná deposit, but also on the change of these properties with a depth of 12–24. floor of the former mine, 550-1200 m below the surface. Realized works included geological, petrographic, geochemical description of the rock environment, geophysical work (esp. seismics), study of physico-mechanical properties of rocks, transport experiments and deposit revalidation of the Rožná deposit. All work was carried out for the purpose of describing the studied zone and its manifestation with an emphasis on ensuring the safety of the potential location of the deep geological repository.

Realization project summarizes the planned work, its progress and continuity within the environment of Rožná I mine in the extent of the procurement „Získání dat z hlubokých horizontů dolu Rožná“ which is being compiled by Hluboké hluboké horizonty Rožná group. The final goal is to clarify the significance and spatial influence of major tectonic fault on surrounding rock mass. The results will help to clarify localization and safety issues of the potential deep underground repository, especially with respect to the Kraví hora locality.
