Huasheng Lin et al., A Review of In Situ Stress Measurement Techniques, Proceedings of the 18th Coal Operators' Conference, Mining Engineering, University of Wollongong, 7-9 February 2018, 95-102.


Changes in stress orientations and magnitudes can have a significant adverse impact on mining conditions such as increasing the risk of violent failures. Knowledge of these changes can indicate the high-risk zones within a mine sites, which will enable mine operators to implement appropriate controls. At deep underground excavations, there are some difficulties in collecting reliable data at reasonable costs and majority of methods provide point measurement per test only. Thus, the utilisation of borehole techniques has received more attentions. In this paper, traditional stress measurement techniques are reviewed, including their pros and cons. Under specific geological conditions, some methods have significant advantages over others. Following the illustration of benefits and shortcomings of these techniques, the development potential of an in situ stress measurement technique using borehole breakout is briefly addressed in conjunction with the future research plan.
