摘　　要：采用ANSYS有限元数值模拟方法动态模拟并计算了三山岛金矿新立矿区中段盘区间不同回采顺序下不同开采步骤的围岩应力和位移状况,结果表明,间隔两个盘区回采一个盘区的方案能取得较好的效果,为三山岛金矿新立矿区海底安全高效回采矿石资源提供了技术支持。By using finite element numerical simulation,a dynamic simulation and calculation were performed for the surrounding rock stress and displacement status when selecting different stoping sequence in the middle section of panel in Sanshandao Gold Mine.Results show that the mining scheme of stoping one at intervals of two panels has a better effect and can provide technical support to the safe and effective undersea mining in Xinli Area of Sanshandao Gold Mine.
