采场空区稳定性数值模拟分析
Numerical Simulation on Stability of Stope Goaf
为研究采场空区的稳定性，在前期现场调查现场原岩应力测定室内试验及岩体力学参数工程处理的研究基础上，应用现代仿真技术与计算机数值模拟技术，利用ANSYS对东坪金矿空区形成过程及采空区稳定性进行模拟计算和预测分析。数值模拟结果表明，采空区顶板发生向下位移，采空区顶板处出现明显的竖直应力集中和水平应力集中，但是没有超过顶板的极限拉应力，因此顶板仍然是稳定的。
o study stability of stope goaf, we performed the in-situ investigation such as field test of rock stress and indoor rock mechanics test and simulated the formation and mining goaf stability of Dongping goldmine using ANSYS. Numerical simulation results show that the roof happen down mined-out area in goaf roof displacement, appear obvious vertical stress concentration and level of stress concentration, but no more than the ultimate tensile stress of roof, so the roof is still stable.
