摘　　要：三山岛金矿新立矿区是我国第一个进行海底采矿的硬岩矿山,国内仅龙口在海下采煤。三山岛矿区矿体位于海床下数十米至数百米范围内,是完全意义上的海底开采,充填法是首选的采矿方法。通过不同浓度不同灰砂比的充填尾砂胶结性能研究,确定充填浓度为70%左右时,胶结充填灰砂比为1∶8,胶结充填面灰砂比为1∶4,并采用岩层微扰上向水平分层充填法开采,为三山岛金矿新立矿区海底安全高效开采矿石资源提供了技术保障。Xinli mining area of Sanshandao gold deposit is the first hard rock mine which belongs to the under-sea deposit in our country,and only Longkou is mining coal under sea in domestic.The orebody in Sanshandao mining area is located in the range of several decameter to several hectometre below the seabed.It is full meaningful submarine mining.And the cut-and-fill method is an optimum mining method.Through research on the commenting performance of filling tailings with different concentration and different comment-sand ratio,it is determined that the whole tailings upward flat-back cut-and-fill stoping method is adopted with comment-sand ratio of 1∶8 in filling and 1∶4 in commenting surface at a filling concentration of about 70%.It provides a technical support for the safety and high efficiency mining of Xinli mining area of Sanshandao gold deposit in the undersea mining.
