Abstract: Mineral deposits are very important valuable materials strengthening the economic development of a nation. The unlimited needs of human being from mineral deposits are leading to the continuous increase in depth of underground mines. Due to the high concentration of ground stress resulting from exploitation of deep mineral deposits, the subsequent frequency of ground pressure hazards is consequently highly increasing, and have strongly hindered the safe and efficient mining. This increased the need for effective underground mine planning and optimization techniques. Adopting rational stope structural parameters is an important measure to realize safe and efficient mining of deep mineral deposits and to control ground pressure hazards. By using large scale nonlinear 3D finite element program, the optimization study of stope structure of deep ore deposit at FanKou Lead-Zinc Mine was carried out through the method of static and dynamic numerical simulation experimental test. The rational stope structural parameters of deep ore deposit exploitation at FanKou Lead-Zinc Mine is recommended to the similar mines elsewhere.
