摘　　要：利用Surpac 6.3矿业软件,依据矿区铝土矿野外地质资料,建立地质数据库,构建了矿区的矿体三维模型。根据地质统计学的原理,将地质数据库中的样品进行组合,并对变异函数进行拟合和验证,建立变异函数模型,获取相应参数。采用普通克里格法对铝土矿矿体进行品位估值与资源量估算,结果较为准确可靠,为今后的勘查工作和定量、定概率预测提供了科学依据。This study built a geological database and a three-dimensional geological model for the bauxite orebodies in Baofeng County of Henan Province using the Surpac 6. 3 mining software based on field geological data of bauxite ores. According to the principle of geostatistics,we combined the samples in geological database,and fitted and verified the variogram to establish a variogram model and obtain corresponding parameters. With ordinary Kriging method,we estimated the grade and resources of the bauxite ores. The results are accurate and reliable,which will provide scientific basis for further exploration and quantitative prediction and probability prediction in this area.
