Estimating in-situ stresses is an important step in the analysis and design of any underground rock excavation. The cost and time restrictions associated with each measurement has prevented the extensive use of the established stress measurement techniques. To evaluate the potential of Kaiser Effect as a reliable and economical stress measurement method, a comprehensive investigation has been undertaken into various aspect of this subject. This paper presents the results of the first stage of a comparative study to determine existing stresses in a rock mass by testing specimens extracted from different drilling orientations. Based on the results obtained so far with the assistance of the Canadian mining industry, it is shown that the Kaiser Effect method could be a viable alternative to other conventional techniques.
