The medieval Jeroným Mine is a mine working in which places of various degrees of rock mass disintegration are there. Time-lapse recording, which has been performed in the Jeroným Mine since the year 2009, was induced by a necessity of documenting both areas of flaking-off and caved areas owing to an increased rate of occurrence of flaking-off phenomena in mine workings - rooms K3 and K4 of this mine. The methodology of recording, which uses as a basis repeated recording in time in the framework of geotechnical measurements carried out quarterly, is based on the principle of maintenance of not only parameters of images themselves, but also of location of a photo device used for documentation provision. This process is followed by the creation of information sheets of areas of flaking-off and caved areas and their classification. The method of recording was used owing to a high degree of disintegration of the rock mass in selected mine workings, a possibility of extension of caved areas and also the high rate of occurrence of subsidence phenomena occurring above those workings and even sporadically reaching the mine workings. Time-lapse recording is thus performed primarily in mine workings with reduced stability, situated very close to the surface. With regard to the principle of this method, results will be known only in further years., Radovan Kukutsch, Petr Žůrek and Martin Stolárik., and Obsahuje bibliografii
Distributed control and measurement system for evaluation of hydrologic, geomechanical and other parameters has been built up in the medieval ore mine Jeroným. The instrumentation is generally based on commercial measurement and control kit and sensors. Technique of implementation of special sensors, e.g. laser distance meter and/or CCBM probe for measurement of rock massif stress changes, is also described. The distributed system is integrated into the existing seis mic recording station equipped by data transmission via GSM network. Comprehensive monitoring system is modular in order to have possibility to change the system configuration., Jaromír Knejzlík and Zdeněk Rambouský., and Obsahuje bibliografické odkazy
