Abstract:Due to the fixed stope structure parameters of an underground mine, the structural of the stope in the mining process can not adapt to the change of the mining stress environment. The roof and surrounding rock caving phenomenon occurs frequently, which brings serious safety hidden dangers to underground production.According to the ore occurrence characteristics and mining technical conditions of the mine, the 3D-σ finite element analysis software is used to simulate the stability of the four stope structure parameters schemes of the mine. The stability of the four stope structural parameters schemes at different burial depths is numerically simulated, and the optimum stope structural parameters at different burial depths are obtained, which provides theoretical support for the stope structural design of the mine.
