摘要：

三山岛海底矿体顶底板的岩石强度高、坚硬，稳固性较好，而断裂附近岩石受其影响，强度降低，稳固性较低，施工前应采用固结等手段，避免造成危害。通过研究分析海底沉陷理论，说明对采空区进行合理的充填接顶是必须的，实施后，充填效果良好。此外，采用微震监测技术对地表变形进行监测，其结果在误差范围之内，且对周边建筑物无影响。

Abstract:

The roof and floor rocks of submarine orebody in Sanshandao are strength,hardness and good stability,but the intensity of rocks near fracture decrease,its stability low,affected by fracture.Consolidation should be used before construction to avoid harm.Through research and analysis seabed subsidence theory,it shows that it is necessary to reasonable roof-contacted filling for gob.Through implementation,we obtain good filling.In addition,using microseismic monitoring technology to monitor ground deformation,which results in the error range,and it has no effect on surrounding buildings.
