  Estimation of in situ stress from borehole breakout for improved understating of shaft overbreak in brittle rock

  Abstract: During deep tunneling or mining infrastructure development, the assumed stress state has significant implications on geomechanical design. Remote measurement of the three dimensional stress state at depth has proven to be a significant challenge and is often assumed from historic tests or the regional tectonic setting. This paper presents a stress estimation methodology using numerical...
