In order to solve the fierce pressure and ore vein direction disorder problems cause by complexity distribution of vein gold and diversity of geological structure,stress measurements of six points is conducted in Tugurige gold ore by means of hollow package postures triaxial strain gauge using borehole stress relief method systematically.The stress measurement data shows that Tugurige gold mine belongs to typical tectonic stress field and the orientations of maximum horizontal principal stress is near to NE,it fit to the geological tectonic compressional movement.The magnitudes of the stresses are medium values.The results also show that the ore vein and the maximum principal stress is approximately vertical.In-situ stress distribution characteristics can give reference for the mine production design and the underground pressure control,provides a preliminary judgment for prospecting direction.
