西岭矿区地应力测量及分布规律研究OA

Xiling gold deposit has become the largest single gold deposit in China.The collection of basic technical data of geostress is of great significance for the rational mining of Xiling gold deposit.In this paper,by using the borehole core during the exploration period,the acoustic emission Kaiser effect point of the core is determined by acoustic emission test,and the magnitude and direction of geostress are further calculated.Finally,the underground geostress distribution law of the whole Xiling mining area is obtained through the geostress measurement results of the selected five boreholes,which provides important data support for the mining design of the mining area.
