近海黄金矿床深部开采科技难题及研究展望

深地资源勘探开发是当前国家和学术界关注的重大科技问题。本研究在全面总结深部开采科技难题和山东黄金集团浅部已有技术积累的基础上,以三山岛金矿近海开采为切入点,系统分析了2 000 m以浅深部开采应解决的深部岩体力学与地应力环境及数据库构建、安全及高效开采、2 000 m深井开凿与提升、深部降温、深部绿色充填工艺技术等关键问题,并对未来应开展的基础理论和相应的应用技术研究作出了展望,旨在为山东黄金深部开采提供指引。

Scientific Difficulties and Research Prospects in Deep Mining of Offshore Gold Deposit

Exploration and exploitation of deep resources are major technological issues in China and academic world.As a basis of comprehensive summary on scientific difficulties in deep mining and the existing technological accumulation in exploitation of shallow resources of Shandong Gold Group,and taking the offshore mining in Sanshandao Gold Mine as breakthrough point,the key problems for shallow or deep mining within 2 000 m were analyzed,including rock mechanics and ground stress environment,database construction,safe and efficient mining,digging and extension of 2 000 m deep shaft,heat-harm controlling and green filling technology of deep mine and so on.Some prospects on the basic theory and corresponding applied technology research were made,in order to provide guidance for the deep mining of Shandong Gold Group.
