玲珑金矿深部开采三维有限元数值模拟研究

Numerical Simulation of Deep Mining of Linglong Gold Mine Using 3-D Finite Element Method

玲珑金矿已进入深部开采 ,其工程地质条件和矿体赋存状况恶化 ,地应力增大 ,地压显现加剧。采用大型非线性三维有限元对深部回采过程中的地压活动规律和围岩稳定性进行了系统分析 。

Due to deep mining, Linglong Gold Mine′s geological environment and orebody occurrence are getting worse and worse, and its underground stress is progressively increasing, thus resulting in an obvious increase in underground pressure. This paper analyses systematically the fluctuating regularity of underground pressure and the stability of rock wall during deep mining using non linear 3-D finite element method. In light of the existing problems of mining method, the authors have made conclusive suggestions for chosing deep excavation methods of Linglong Gold Mine.
