摘要
根据阜山金矿地质资料，用有限元法模拟了不同采充高度采场的应力场和位移场．结果表明：采用尾矿充填并配合上盘锚杆是维护围岩稳定性的有效方法；合理的采夫高度是分层高度为4m，最大控顶距为6m．该结论可用于指导采场的设计．
According to geological data of Fushan gold mine, the stress field and displacement field for different height of mining and filling was simulated with means of limited elements. As a result the adoption of gangue filling and upper tray used anchor pole is an effective method for preserving all round rock. The height of cent layer is 4m and the most space is 6m with a reasonable height of mining and filling. It can guide thedesign of stope.
