ABSTRACT: A low cost methodology that allows the determination of in-situ stress using oriented core specimens has been investigated. The technique can be used to determine the stresses during the early stages of a project, even in undeveloped areas of a mine. Initially the research aim was to compare the experimental results estimated by the AE and DRA methods to those estimated by the HI cell measurements. Subsequent studies have been focused on full stress tensor determination from a single oriented cored rock. In all cases the rock core specimens recollected the in-situ stress reasonable well compared with the standard overcoring method.
