摘　　要：三维地质模型是对不同地质体、地质构造及其空间展布特征进行3D展示的一种先进的科学技术方法,为了促进诸广地区鹿井铀矿田铀矿找矿勘探工作,文章建立了地形地貌、构造、地层-岩体及矿体三维地质模型。在满足探测目标和钻孔施工要求的前提下,利用三维地质模型开展了龙头-沙坝子钻探选址,并进行了钻探验证。钻探验证结果达到了钻探设计的初衷,同时证明诸广地区具有良好的铀矿找矿前景。研究表明,利用三维地质模型为钻探设计提供了更直观的参考,在勘查工程设计方面具有广阔的应用推广空间,在区域找矿预测及找矿勘探工作中具有重要的实际意义。The 3D geological modeling is an advanced scientific and technological method for 3D display of different geological bodies,geological structures and their spatial distribution characteristics.In order to strengthen the prospecting of granite-type uranium deposit in Lujing uranium ore field in Zhuguang area,we established 3D geological models of topography,structure,stratigraphy-intrusion and ore body.Under the premise of the detection target and drilling construction requirements,the deep drilling site selection was carried out in the Longtou-Shabazi area by the three-dimensional geological modelling,and the drilling verification work was also carried out.The drilling verification results was found reaching the original goal of the deep drilling design and proved that Zhuguang area had good prospecting prospects for granite-type uranium deposits.The study showed that the 3D geological modelling can provide more intuitive reference for the deep drilling design,and has important practical significance in regional prospecting prediction and prospecting and broad application space in exploration engineering design.
