中文摘要：
为了解决复杂地质体建模困难、精确度低等问题，综合考虑已有平面地质资料，基于OO-Solid数据模型，提出了改进的分区协同建模方法：采用分区协同思想将复杂地质体交叉剖面线由三维体元概念转化为二维面元概念，由复杂统一整体转化为简单分区区域个体，最后通过分区区域面元的合并包容得到复杂地质体的三维体元模型。将该方法应用于云南个旧某锡矿山，研究结果表明：高效快速构建出的三维复杂地质体模型，不仅揭示了该复杂地质体的成矿机理，而且真实反映了地质体的赋存情况，为矿山后续工作（矿体储量计算、矿体勘探、稳定性分析模拟等）提供了准确的基础资料。
英文摘要：
A district collaborative modeling method based on OO-solid model was proposed for solving difficulties and low accuracy in complex geologic modeling, taking the existing plane geological information into comprehensive consideration. An idea of district collaboration was adopted in this method to transform the concept of 3D volume element in complex geologic modeling into 2D surface element. Thus the complex integral part was changed into simple individual district. Finally, 3D geological body model was obtained by combining individual district surface elements. The application of method in a Tin Mine in Gejiu of Yunnan Province showed that the 3D complex geologic model which was constructed efficiently and quickly, can reveal its mineralization mechanism and reflect its real storage situation. Moreover, it provides accurate data for the mine＇s follow-up works （reserve calculation, orebody exploration, stability analysis and simulation）.
