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,矿山研究采用机械化上向水平分层全尾砂充填法开采。通过无轨采准系统工程优化研究,确定分层高度为3.3 m,当矿房宽度采用15 m左右时,分段高度采用10～13.3 m比较合适。应用效果证明,优化设计为新立矿区海底矿石资源安全经济开采提供了技术保障。
Sanshandao Gold Mine Xinli Mining Area is the first hard rock mine to carry out seabed mining in China. The mining research adopts mechanized horizontal mining with full tailings filling method. Through the research on the optimization of trackless acquisition system engineering, the stratified height is determined to be 3.3m. When the width of the mine is about 15m, the height of 10 ~ 13.3m is appropriate. The application effect proves that the optimized design provides the technical guarantee for the safety and economic exploitation of seabed ore resources in Xinli mining area.
