摘　　要：三山岛金矿新立矿区矿体赋存于海水之下,开采过程中不允许出现岩层移动与变形,在整体规划采准工程、回采顺序、矿柱尺寸、矿柱布置方式、顶底柱厚度、回采工艺等参数的前提下,通过数值分析,得出大规模开采下的海床形变规律,提出合理的开采方法与结构参数。Orebody of Xinli mining area of Sanshandao Gold Mine is under the sea, strata move- ment and deformation which lead to penetration of sea water are not allowed in mining process. On the premise of overall planning of stope structure parameters and mining technology parameters of mining en- gineering, mining sequence, size and arrangement mode of pillar and thickness of roof and bottom pillar, through numerical analysis, seabed deformation laws under large-scale mining are obtained, while the reasonable mining methods and structure parameters are proposed.
