摘要
三山岛金矿是目前国内少有的海底金属矿,矿山目前采用点柱式上向水平分层充填采矿法,采矿过程中保证点柱与岩体组成的复杂框架式矿柱结构的稳定性至关重要。利用ANSYS有限元分析软件模拟分析了采场在点柱大小固定的情况下、不同柱网参数条件下的围岩稳定性,获得了矿柱间柱70m的最合适柱网设计参数,为海底基岩矿床采场尺寸设计提供了一条有效途径。
Shandong island gold deposit is under seabed.Now the enterprise uses upwards horizontal lamination backfill mining method,so it is essential to assure the stability of mining structure which consists of post pillar,wall rock and roof.The surrounding rock stability of stope under the conditions of the size of post pillar was changeless but spacing pattern parameter of post pillar was different was simulated by finite element analysis software ANSYS,The presented optimum post pillar's space is 10 m.The numerical simulation provides an effective way to the dimension design of stope for mining the gold deposit under seabed.
