Method for determining in situ absolute magnitude and direction of stress and stress concentrations in walls, pillars and other structural parts of underground mines; also by making measurements at distance from surface of underground openings, magnitude and direction of stress field, (state of stress in rock before mining) can be ascertained; results from underground measurements in 5 rock types and number of conclusions that are derived therefrom.
