Long-term experience with stress state determination using CCBO probe in various rock mass
Original language description
The strain gauge probes of different construction are typically used for determination of stress state of rock mass. The modified overcoring method with the original name Compact Conical ended Borehole Overcoring method (CCBO) for rock mass stress measurement is now commonly used. A conical probe was designed by the Institute of Geonics of the Czech Academy of Sciences (IGN) in cooperation with Kumamoto University in Japan. Many stress measurements using the CCBO probes were carried out in the recent past. These measurements were performed in varied rock mass adjacent to mine excavations. As demonstrated in the particular measurements present in this paper, the deformation responses of rock core can vary in sedimentary, metamorphic or igneous rocks. Some overcoring stress measurements provided implausible data due to high grade rock mass anisotropy. Influence of rock mass properties on evaluation presented in this paper is the main goal of this study.
