摘　　要：鸡公岭磷矿属于大型海相沉积磷块岩矿床,极具开发价值。因该矿深埋地下,矿山开采巷道等工程建设和矿山生产必将对原始地质结构产生破坏,可能产生矿产安全和地质灾害防治等问题。本项目通过野外工程地质调查和综合研究,分析了矿区岩土特征并进行了合理的评价分类;查明了矿区危岩、崩塌、滑坡等不良工程地质现象;进行了工业场地工程地质评价和矿层顶底板的稳定性评价,为矿山开采设计提供科学资料,保障矿山开发利用创造出更大的效益。Jigongling Phosphate Mine is a large marine sedimentary phosphate rock deposit,which has great development value.Because the mine is deeply buried underground,the construction of mining roadway and mine production will destroy the original geological structure,which may involve measures such as mineral safety production and geological disaster prevention and control.Through field engineering geological investigation and comprehensive research,the geotechnical characteristics of the mining area were found out,reasonably evaluated and classified.Adverse engineering geological phenomena such as dangerous rock,collapse,and landslide in the mining area were found out.The engineering geological evaluation of the industrial site and the stability evaluation of the roof and floor of the ore bed were carried out,which provided scientific data for the mining design and ensured greater benefits for the development and utilization of the mine.
