Abstract:Hongtoushan copper mine is a deeper metal mine with typical rock burst. For understanding the state and distribution of stresses in the mine,in-situ stress measurement is carried out by means of hollow inclusion gauge method. Three dimensional stress state is obtained for five levels and eight sites through in-situ stress measurement. The measurement results indicate that the orientation of the major principal stress is NNW~NW,and the value of it is linerally increased with depth. The in-situ stresses are varied with different positions at –767 m level,and the value of the major principal stress reaches around 50 MPa.
