3D geomechanical numerical model of roadways, building of underground research facility (URF) Bukov II. stage
Souček, Kamil ; Gong, Libin ; Waclawik, Petr ; Vavro, Martin
Spin-off plant GEAM of DIAMO, state enterprise, intends the construction of 2nd stage of the underground research facility (URF) Bukov in the area of the Rožná uranium deposit. The aim of this work is to compile the 3D mathematical geomechanical model of projected URF excavations in software for numerical modeling FLAC 3D. The main output of numerical modeling is the analysis of the “strength factor” distribution (SF factor) reflecting the stability of the rock mass after the excavation of laboratory roadways and testing chambers of URF

Final Report of the Project „Data Acquisition from the Deep Horizons of the Rožná Mine“ presents the results of the study of rock mass properties with respect to the presence of a significant tectonic zone. The study focused on the change of properties in the vicinity of the so-called first zone of the Rožná deposit, but also on the change of these properties with a depth of 12–24. floor of the former mine, 550-1200 m below the surface. Realized works included geological, petrographic, geochemical description of the rock environment, geophysical work (esp. seismics), study of physico-mechanical properties of rocks, transport experiments and deposit revalidation of the Rožná deposit. All work was carried out for the purpose of describing the studied zone and its manifestation with an emphasis on ensuring the safety of the potential location of the deep geological repository.
Evaluation of fracture response of Silesian granite specimens via Effective Crack Model approach and finite element analysis
Malíková, L. ; Vavro, Leona ; Vavro, Martin ; Keršner, Z.
The paper is focused on the advanced evaluation of fracture tests of selected rock specimens. Assessment of fracture response of chevron notch cylindrical specimens of Silesian granite subjected to three-point bending test was performed. The effective crack model is used and academic software chevroncylinder (author Petr Frantík) based on the finite element method is applied for the analyses. Based on the described procedures, estimation of maximum values of the effective fracture toughness are established and discussed.
Characterization of Božanov sandstone: pilot fracture tests
Kumpová, I. ; Rozsypalová, I. ; Vavro, Leona ; Vavro, Martin ; Keršner, Z.
The aim of this paper is a characterization ofsandstone from Božanov quarry near Broumov, Czech Republic,by means of the pilot fracture tests. Five drill-core test specimens withnominal diameter of 50mm and lengths of 100 and 125mmwere provided by an initial chevron type notch. Specimens were loaded in the configuration of the three-point bending as a displacement driven experimentusing LabTest 6.250 equipment in the laboratory of the Institute of Building Testing, Faculty of Civil Engineering, Brno University of Technology. The load versus displacement diagrams were used to quantify the basic mechanical fracture parameters of the studied sandstone: modulus of elasticity, fracture toughness, toughness, and specific fracture energy.
