Collection and analysis of data from four voltage probes, SP-47 in the gallery Josef at Mokrsko within the the project MPO FR-TI3/325
Staš, Lubomír ; Souček, Kamil ; Nohejl, Zdeněk ; Kaláb, Tomáš ; Rutar, Tomáš
Text, including tables, graphs and images is a comprehensive annual report to the Treaty on the work of 823/24/10 data collection and evaluation of 4 pieces voltage probes, SP-47 in the gallery Josef at Mokrsko. It contains the results of the evaluation of the measurements of voltage changes in test wells in the immediate vicinity of the borehole stress - thermal sources in solid exploration adit SP-47 in Josef. All measurements were obtained using a strain gauge measuring the conical heads, specially manufactured and installed here for this purpose. Measurements are carried out within the project MPO-TIP FR-TI 3/325 - The importance of the thermal load of rocks - perspectives underground storage of thermal energy.

The X-ray CT lab and the research at the Institute of Geonics AS CR
Souček, Kamil ; Staš, Lubomír
In recent decades, non-destructive methods of materials analysis (Desrues 2006) have been used increasingly for the study of different kinds of materials. Especially, it concerns the method of the X-ray computed tomography (CT). This technique was invented in 1970's (Hounsfield 1972) and it quickly became an indispensable part of medicine. In the 1980's, this success in medicine encouraged the research and development of the X-ray CT applications in the field of materials engineering and consequently also in the field of geomaterials (Otani, Obara 2004). Nowadays, many applications are possible due to high resolution of individual building units in the tomographic cross-sections (so called voxels) with dimensions of units or tens of micrometres. To get this resolution, the use of the 2D and the 3D high-resolution X-ray CT, or the micro-CT with micro-focal sources of X-rays, and suitable linear or flat (2D) X-Ray detectors are preferred.

Annual report on the project FR-TI3/579 in the TIP project in 2013
Staš, Lubomír
A complete methodology for determining the initial stress tensor of convergence measurements on the two profiles perpendicular to the longitudinal axis of the tunnel was developed and implemented. It was designed and tested algoritmus for optimization that allows to design the location of measurement points in advance on a pair of rails so that measurement errors are eliminated. It was designed a new methodology for measuring convergence, based on the use of a laser beam. Measurements were carried out at the convergence of three different profiles in Dolní Rožná locality.
