Kajzar, Vlastimil
2019 - Czech
In the northern area of the Doubrava and Karviná Mines I mining districts on the border of the cadastral district Dětmarovice and Doubrava, mining operations are underway. For this reason, in order to identify possible mining effects on the surface and surface objects, the stabilized points in this area are surveyed regularly twice a year. Since 2014, the Institute of Geonics of the CAS in Ostrava has been selected as the contractor of these works. In June and October 2019, the surveying stages planned for this year were carried out, during which altogether 4 interconnected leveling routes, which are formed by these points, were carried out. V severní oblasti dobývacích prostorů Doubrava a Karviná Doly I na hranici KÚ Dětmarovice a Doubrava se realizují dobývací práce. Z toho důvodu jsou za účelem zjišťování možných důlních vlivů na povrch a povrchové objekty pravidelně dvakrát ročně výškově zaměřovány body v této oblasti stabilizované. Od roku 2014 byl za zhotovitele těchto prací vybrán Ústav geoniky AV ČR, v. v. i., Ostrava. V červnu a říjnu 2019 se uskutečnily měřické etapy plánované v tomto roce, během kterých bylo prováděno výškové zaměření celkem 4 vzájemně navazujících nivelačních tras, které jsou těmito body tvořeny.

Assessment of primary rock mass stress by overcoring method using CCBO probes, Mine Rožná
Staš, Lubomír; Waclawik, Petr; Souček, Kamil; Vavro, Martin; Kukutsch, Radovan; Nohejl, Zdeněk; Rutar, Tomáš
2019 - Czech
The measurement of the stress state of the rock mass was performed on the 20th level of the liquidated uranium mine Rožná. This site was selected as one of the possible test sites of the planned geotechnical and geophysical methods. As part of the measurements, a series of four measurements of the 3D stress tensor were carried out within the sub-horizontal (approx. + 5 °) borehole with a diameter of 76 mm. To measure the primary stress of the rock mass, the overcoring method was used using a compact conical probe, developed at the Institute of Geonics AS CR, v.v.i. in collaboration with the Japanese University of Kumamoto under the original name Compact Conical ended Borehole Overcoring method (CCBO). The research report summarizes the results of the performed measurements. Měření napěťového stavu horninového masivu bylo provedeno na 20. patře likvidovaného uranového dolu Rožná. Tato lokalita byla vybrána jako jedna z možných testovacích lokalit celého souboru plánovaných geotechnických a geofyzikálních metod. V rámci měření se podařilo uskutečnit sérii 4 měření 3D napěťového tenzoru v průběhu realizace subhorizontálního (cca + 5°) jádrového vrtu průměru 76 mm. Pro měření primárního napětí horninového masivu bylo použito metody odlehčeného jádra (overcoring) s užitím kompaktní sondy kuželového tvaru, vyvinutou na Ústavu geoniky AV ČR, v.v.i. ve spolupráci s japonskou universitou Kumamoto s originálním názvem Compact Conical ended Borehole Overcoring method (CCBO).

Determination of rock mass failure using acoustic and optical television - metamorphic rocks, Rožná Mine
Staš, Lubomír; Waclawik, Petr; Souček, Kamil; Vavro, Martin; Kukutsch, Radovan; Rutar, Tomáš; Nohejl, Zdeněk
2019 - Czech
In order to evaluate the geological structures on the core boreholes walls, using optical and acoustic logging methods (OBI and ABI) the boreholes were logged at the Rožná Mine. Oriented recording of the walls was performed using optical television (OPTV - Optical TeleViewer) in the horizontal borehole (VRT-H). The optical recording was supplemented by the acoustic television record (HiRAT - High Resolution Acoustic Televiewer) in the down borehole (VRT-U). The measured oriented records by OBI and ABI methods were processed and evaluated in WellCAD software for logging data processing. Based on the evaluated structural data, a structural cross-section was constructed, which was the background material for correlation with geophysical data. Za účelem zhodnocení strukturních prvků zachycených vrtnými stvoly jádrových vrtů byla na Dole Rožná provedena karotáž vrtů pomocí metod optické a akustické karotáže (OBI a ABI). V horizontálním vrtu (VRT-H) byl proveden orientovaný záznam stěn pomocí optického televizoru (OPTV - Optical TeleViewer). V úpadně vedeném vrtu (VRT-U) byl optický záznam doplněn akustickým televizorem (HiRAT - High Resolution Acoustic Televiewer). Naměřené orientované záznamy metodami OBI a ABI byly zpracovány a vyhodnoceny v softwaru WellCAD pro zpracování karotážních dat. Na základě vyhodnocených strukturních dat byl konstruován strukturní řez, který byl podkladovým materiálem pro korelaci s geofyzikálními daty.

Adsorption of pharmaceuticals from aqueous solutions onto clay minerals
Vallová, S.; Sokolová, B.; Valovičová, Věra; Plevová, Eva
2019 - English
The objective of this work was to investigate to possibility of clay minerals for the removal of drugs from aqueous solutions. Natural minerals such as montmorillonite, vermiculite, kaolinite and modified montmorillonites KSF and K10 (intercalated by Fe3+) were used as potential sorbents for three analgetics: paracetamol, ibuprofen and diclofenac from aqueous solutions. This research demonstrated that adsorption of all three pharmaceuticals onto natural untreated clay minerals, except paracetamol sorption on Na-MMT, is negligible. On the other hand, the chemically modified montmorillonites demonstrated significant sorption ability in the order diclofenac>ibuprofen>paracetamol.

Possibilities of using 3D laser scanning in geotechnical practise
Kukutsch, Radovan; Kajzar, Vlastimil; Šňupárek, Richard; Waclawik, Petr
2019 - English
We are experiencing the penetration of modern and smart technologies in all sectors of human activity, including mining and geotechnics. One of these technologies is 3D laser scanning, which has seen significant technological advancements over the last decade and has become an integral part of underground construction monitoring as a tool to enable comprehensive, accurate and unbiased capture of the spatial situation in digital form. This development was behind the fact that since 2013, 3D laser scanner has been used by the Institute of Geonics of the Czech Academy of Sciences as a necessary part of the geotechnical monitoring of mine works, when it is possible to precisely detect and quantify the time-space changes caused by man's intervention in the rock mass compared to the traditional established measuring methods. A leading project of recent years was the monitoring of the strain stress state of the rock massif during the 30th seam extraction during the trial operation of the Room and Pillar extraction method in the CSM Mine shaft safety pillar where, besides many other measuring instruments, 3D laser scanning was used for the convergence measuring of roadways, especially for capturing any deformation changes on the permanent pillars. A complementary function was the comparative evaluation with the results of other tools, e.g. with data measured by horizontal extensometers. The subject of the article will be a general description of the possibilities of using 3D laser scanning in geotechnical practice on spatial data acquired during the monitoring lasting almost 3.5 years, when important phenomena were detected in the movement of the pillar walls and the floor heave in the CSM Mine in the tens of cm, sometimes up to 100 cm.
