Study on 3D ground stress surveying and distribution rules for No.1 deposits in Huogeqi Copper Mine

The methods,process and results of 3D ground stress surveying for No.1 deposits in Huogeqi Copper Mine are introduced in this paper.Through the surveying on 5 points in three middle segments,the deep ground stress status and distribution rules are obtained,which can provide accurate basic data of ground stress for subsequent mining and roadway support.
