以安徽铜陵凤凰山矿田为例.通过综合地质研究,构建了矿体定位预测概念模型.在地质勘探数据和物化探数据集成的基础上,采用三维地质建模技术,对地层、构造、岩浆岩、矿体等地质体进行了推断和圈定,构建了地质体的线框模型与块体模型.基于定位预测概念模型和地质体三维块体模型,通过地质空间定义和立体单元划分,建立了岩体及其表面形态起伏、接触带、地层、褶皱、断层等控矿地质因素的三维栅格场模型.在定量分析控矿地质因素与矿化分布的关系的基础上,建立了反应这种关联关系的矿体立体定量预测模型.预测模型提供矿田深部(-1000m标高以上)所有50m×50m×50m立体单元的铜品位、铜金属量和含矿概率的预测结果.基于预测结果圈定了4个深部找矿立体靶区,为深部找矿工程的设计、布置提供尚未发现的臆伏矿体的位置、品位、金属量等信息的指导.

By taking the Fenghuangshan ore field in Tongling, Anhui as a case study, the concept model for ore body location predication was built through the general geological investigation of the ore field. Based on the integration of geological geophysical andgeochemical exploration data, the geological bodies such as strata, structures, magmatic bodies and ore bodies were inferred and delineated by means of three-dimensional geological modeling, and then the wireframe and block models of the geological bodies wereconstructed. From the concept model of location predication and the 3D block models of geological bodies, we've obtained thethree-dimensional raster models of the geological ore-controlling fields of the magmatic body and its surface relief, the contact zone,the strata, the folds, the faults and so on. By analyzing quantitatively the correlation relationship between the geological ore-controllingfactors and the mineralization distribution, the stereoscopic quantitative predication models of ore bodies to reflect the relationship wereset up. With the predication models, the predication results, including copper grade and copper tonnage of all cubic cells with size of 50m×50m×50m in die deep parts (above the elevation -1000m ) of ore field were provided. On the basis of the predication results, 4 cubic target areas for deep prospecting were delineated, which provides guidance on the location, grade, tonnage and other information of undiscovered concealed ore bodies for the design and layout of deep prospecting engineering.
