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
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.
