Experimental ultrasonic measurement of the rock specimens
Lednická, Markéta
This contribution describes ultrasonic measurement of the various rock specimens in laboratory conditions. Instrumentation PUNDIT plus was used for this experimental measurement on the rock.
Seismic Loading of Medieval Mine Jeronym near Čista in 2008 and Distributed Measuring System
Kaláb, Zdeněk ; Knejzlík, Jaromír ; Kukutsch, Radovan ; Lednická, Markéta ; Rambouský, Zdeněk ; Dombková, Anna ; Makovský, Jaroslav
Výzkumná zpráva navazuje na zprávu z loňského roku a popisuje dokončení vybudování distribuovaného měřicího systému. Ve zprávě je podrobně hodnoceno seizmické zatížení důlního díla v roce 2008, zvláště s ohledem na seizmický roj na Kraslicku. Představeny jsou také výsledky studia povrchových útvarů – pinek.

Výzkumná zpráva navazuje na předchozí zprávy a popisuje sledování geomechanické stability důlního díl Jeroným v roce 2008. Je hodnoceno seizmické zatížení, povrchové útvary, geologický a geotechnický monitoring.
Novodobá historie Dolu Jeroným - zajištění Dolu Jeroným v datech
Kukutsch, Radovan ; Bernard, J. ; Žůrek, P. ; Kořínek, R. ; Kaláb, Zdeněk ; Lednická, Markéta
Modern history of Jeroným Mine is no longer so obvious, moreover at a time when the number of activities carried out in the Jeroným Mine has the growing character. Effort of author's team is documenting these activities from the moment, when was Mine Jeroným rediscovered and secured by the help of former Rudné doly Příbram. Contribution maps fundamental activities of each year - securing the mine, hereditary adit coping, the reconstruction of blind shaft Jeroným etc., but also clearly demonstrates the activities carried out by VŠB-TU Ostrava and the Institute of Geonics AS CR, v.v.i. within each grant and scientific tasks.
Evaluation of stability and stress-strain conditions of K2 chamber in Jeroným Mine
Hrubešová, E. ; Kořínek, R. ; Lednická, Markéta
This paper deals with mathematical modelling of stability and stress-strain conditions in medieval mine workings named Jeroným (near Čistá, Sokolov District). Two main topics are discussed: current state and prediction of situation during planned building operations for reconstruction of some parts. Paper presents basic conditions and presumptions of models, characteristics of partial results. Analyses of first results from modeling of mine room named K2 (transverse cross sections) using Plaxis programming system are presented.
Pohyb důlních vod v mělkém středověkém Dole Jeroným (Česká republika)
Kaláb, Zdeněk ; Hrubešová, E. ; Knejzlík, Jaromír ; Kořínek, R. ; Kukutsch, Radovan ; Lednická, Markéta ; Žůrek, P.
Mine waters in the Jeroným Mine can be divided into following types: running, influent and flowing waters, water accumulated in closed drainless expanses, waters in expanses with natural or man-made outflow. Mine water flow is significant, small drain exists in some parts during the whole year. First sudden and significant increasing of mine water level is obviously related with marked changes of surface water amount (spates or snow-melt). Low increases of water level are not always dependent on precipitation amount and there other influencing factors exist probably.
Distributed control and measurement system and seismic loading of the medieval Jeroným Mine in 2007
Kaláb, Zdeněk ; Knejzlík, Jaromír ; Lednická, Markéta ; Rambouský, Zdeněk ; Dombková, Anna ; Makovský, Jaroslav
Report under discussion summarized evaluation of distributed control and measurement system in medieval ore mine Jeroným. Current values of geomechanical and geotechnical parameters and seismic loading in 2007 are presented in this report.
Application of ultrasonic measurement of the granite specimen in laboratory conditions
Lednická, Markéta
This contribution describes ultrasonic measurement of the granite specimen in laboratory conditions. Instrumentation TICO was used for this experimental measurement on the rock. Changes in spreading velocities detect existence of fissure in the granit specimen.
Applicability of Apparatuss TICO for Ultrasonic Measurements in Ancient Mine
Kaláb, Zdeněk ; Lednická, Markéta
This contribution describes first measurement that was performed in the Jeroným mine near Čistá using ultrasonic method. Spreading of these waves was detected up to 1 m distance between source and detector (instrumentation TICO). The main problem appears that vaseline (plasticine) very quicly hardens and transfer of vibration energy is not good.
Mine Jeroným Displayed in the Ancient Maps and Sketchs
Kaláb, Zdeněk ; Lednická, Markéta ; Kukutsch, R.
This paper deals with summarizing of old documentation that has some information about medieval Mine Jeroným near Čistá (Sokolov District). During fire in 1772, all technical documentation was destroyed. Therefore, it is necessary to look for information in old maps and other materials that are in several muniment-rooms.
