摘　　要：以湖南铲子坪金矿床为研究对象,探索三维地质勘探工程数据库、地层及矿体模型的建设,以期为金矿床三维地质模型的建立提供示范。在矿体建模过程中,采用金品位双指标法,精确地反映了矿体的产状和分布,与传统方法相比提高了模型精度。基于三维矿体模型,运用统计学法开展资源储量估算,并与传统块段法运算结果进行对比,其各项指标相对误差均在允许范围内,统计学法在储量估算中更加合理且切合实际、速度更快。With the Chanziping gold deposit in Hunan as the object,the construction of the 3D model for geological exploration engineering database,stratum and ore body was explored to demonstrate the establishment of 3D geological model of gold deposit.During ore body modeling,the gold grade double-index method was adopted to exactly reflect the occurrence and distribution of ore body and the accuracy of the model is improved compared with the traditional method.In addition,based on the 3D ore body model,the statistical method was used to estimate the resource reserves.Compared with the calculation results of the traditional block method,the relative differences of all indexes are within the allowable range.The statistical method is more reasonable,practical and quicker for reserve estimation.
