Structural mapping of exploration geotechnical boreholes walls within 2nd phase – Decline
Waclawik, Petr ; Schuchová, Kristýna ; Kukutsch, Radovan ; Georgiou, Lucie
Structural-geological analysis, i.e. fracturing assessment of the walls of geotechnical boreholes (CIS38 and CIS39) within the projected Decline in lithium exploratory area was carried out on the basis of optical (OPTV) and acoustic televiewer (HiRAT) records evaluation. HiRAT and OPTV probes are part of the Robertson Geologging logging equipment. The apparatus has an electric winch with a four core logging cable, which transmits the data recorded by the probes via a data logger to a computer. The spatial data obtained from interpretation of the geotechnical boreholes records were structurally analysed. The submitted research report comprehensively summarises the findings obtained from the structural mapping of geotechnical boreholes. On the basis measured data the rock mass quality evaluation of boreholes walls were additionally done. The complex data have been allowed very precise analysis of rock mass structural conditions, which are necessary for design of opening mine working.

Structural-geological analysis, i.e. fracturing assessment of the walls of geotechnical boreholes (CIS12, CIS14, CIS31 and CIS37) within the Ore Zone lithium exploratory area was carried out on the basis of optical (OPTV) and acoustic televiewer (HiRAT) records evaluation. HiRAT and OPTV probes are part of the Robertson Geologging logging equipment. The apparatus has an electric winch with a four-core logging cable, which transmits the data recorded by the probes via a data logger to a computer.

The submitted research report comprehensively summarises the findings obtained from the structural mapping of geotechnical boreholes. On the basis measured data the rock mass quality evaluation of boreholes walls were additionally done. The complex data have been allowed very precise analysis of rock mass structural conditions, which are necessary for construction geomechanical model.

Rentgenová počítačová tomografická analýza čtyř zkušebních těles betonu na bázi ocelárenské strusky a umělého hutného kameniva
Souček, Kamil ; Georgiou, Lucie
Byla provedena vizualizace vnitřní stavby, hodnocení struktury a základní analýza pórovitosti na čtyřech betonových zkušebních tělesech. Pro analýzu zkušebních těles byla použita nedestruktivní metoda průmyslové 3D rentgenové počítačové tomografie. Na základě zobrazení CT řezů jednotlivých zkušebních těles betonu byly identifikovány jeho čtyři základní složky betonu (i) cementový tmel, ii) frakce tvořena ocelářskou struskou, iii) frakce tvořena umělým hutným kamenivem, iv) poslední složka betonu je zastoupena póry). Provedená CT analýza pórovitosti stanovila průměrnou pórovitost vyšetřovaného betonu na úrovni 6,5 ± 1,52%.\n
