Abstract Reliable evaluation of in situ stress is an important phase in the analysis and design of underground excavations, particularly for evaluating the stability of underground structures to prevent failure or collapse. A low-cost and reliable technique for the estimation of the full stress tensor based on acoustic emission (the Kaiser effect) has been developed at the WA School of Mines over last five years. This paper presents the results for a feasibility study where four AE measurements for an Australian mine have been carried out. The results are compared well with those obtained by the conventional hollow inclusion over-coring method (HI Cell). The advantages of the AE technique are that it is relatively cheap, non-time consuming and is applicable to in situ stress measurements at depth in remote regions.
