  • The Sanshandao gold mine is situated on the seashore frontier of the Laizhou Bay in Sandong Province, the engineering geology and hydrogeology conditions of the mine area are more complex. For this reason, there exist some specific geoengineering problems for underground mining of the gold mine. In this paper the characteristics of stress field are studied by using analysis method of geomechanical structural lines, in situ stress measurement and experiment method of Kairser effect of acoustic emission, respectively. The results suggest that the current tectonic stress in the mine area is N40E or so, NE = 110 bar or so,NE : V : NW = 1 : 0. 9 : 0. 65. This provides basic mechanical parameters or the stability evaluation of the underground mining.
