摘　　要：为了建立多层DEM矿体模型,实现矿体逼真的三维可视化,使矿体的体积和土方量计算更为准确,利用宝日希勒露天矿钻孔数据,建立钻孔数据库,并对建模方法进行分析和研究,选择基于不规则三角网的层面建模方法,通过逐点插入法建立各个层面三角网,采用局部法对断层进行处理,按照矿体的空间顺序建立矿床实体模型,在建立宝日希勒露天矿体层面模型的基础上,采用C#和AE技术,实现钻孔数据的查询、放大、缩小等功能。In order to establish a multi-layer DEM ore body model and realize the realistic three-dimensional visualization of the ore body,it makes the calculation of ore body volume and earthwork more accurate.With the strip mine of Baorixilei data,for example,establishment of the geological drilling database.And the modeling methods are analyzed and researched.The modeling method of based on Delaunay TIN is chosen in multitude modeling methods and establishes coal bed model according to spatial order.Based on the three-dimensional geological mode,with the help of secondary development of C# and ArcEngine,we can come true the query and zoom of drilling data.Based on it,use of geostatistical analyst.
