Abstract: The overall structure and principal functions of three-dimension geological modeling and visualization system were discussed. It was used in Anqing copper mineral exploration. The system is mainly composed of three-dimension structure modeling , three-dimensional attribute modeling and three-dimensional geological visualization. Based on the modeling functions and the actual data of Anqing copper mineral exploration, three-dimensional geological models were built. Through the visual analysis, good prospects for exploration were revealed by the extension trend to east southerly direction of copper iron ore. It shows that the three-dimensional geological modeling and visualization system will be very helpful for enhancing the efficiency and accuracy of mineral prospecting to build.

Key words: three-dimension, geological modeling, visualization, Anqing copper mine

摘要： 阐述了所构建的三维地质建模及可视化系统总体结构及主要功能，并结合安庆铜矿勘查实例对其加以应用。该系统主要包括三维结构建模、三维属性建模和三维地质可视化等子系统。基于建模系统功能，利用安庆铜矿实际勘查数据，获得三维地质建模结果。经三维分析认为，该地区铜铁矿向东偏南方向延伸的趋势揭示了较好的找矿方向，进而表明该三维地质建模及可视化系统在提升矿产勘查效率和准确性方面具有良好的应用前景。
