Research on Prevention of Rock Burst in Deep High-stress Area of Fankou Deposit

Li Xuefeng~(1,2), Xie Changjiang~2(1.KunMing University of Science and Technology, Kunming, Yunnan 650093, China; 2.Changsha Institute of Mining Research, Changsha , Hunan, 410012, China)  
The prevention and control of rock burst are of great significance for safely exploiting deep deposit in high-stress area. Based on the analyses of the physical and mechanical properties of ore/rock and the behavior of ground stress field in the deep deposit of Fankou Lead-zinc Mine,the authors researched the unloading measures to prevent and control rock burst in mining the deep deposit, and carried out numerical simulations of the stress distribution under different unloading mining situations by means of 3-D elastic-plastic finite element program, so as to give decision-making basis for controlling rock burst in exploiting the deep deposit of Fankou Lead-zinc Mine.
