摘　　要：新疆鄯善县彩霞山铅锌矿是中天山地区较大型的沉积改造型铅锌矿床,本文将三维建模和立体预测这一新技术新方法应用于该矿床,以矿区勘探工程数据为数据源,建立了该区的地表模型、矿床实体模型、矿块模型等,以图形图像方式逼真再现三维矿体的空间几何形态,分析矿体的空间展布和相互关系,在此基础上分别运用传统方法和现代地质统计学方法进行可视化的储量估算,同时结合矿床实体模型和矿区重力反演数据进行大比例尺三维立体预测,为打造数字化矿山提供理论依据和技术支持。The Caixiashan lead - zinc deposit in Xinjiang is a large - scale sedimentary - reformation one located in the middle Tianshan Mountains of Xinjiang. In this study,we applied three - dimensional modeling and stereo prediction to this deposit based on the exploration data. We created the surface model, deposit physical model and ore block model for this deposit, and displayed the 3D geometry of the ore body in images. Then we analyzed spatial distributions of ore bodies and their mutual relationships and made a visual reserve estimation using the traditional method and modem geological statistics. In combination of the ore - body model with gravity inversion ,we conducted large - scale 3D prediction of ore bodies. The results of these efforts will offer theoretical evidence and technical support for construction of a digitized mine.
