摘　　要：针对司家营铁矿成矿类型以及矿体的分布特征,在对全铁化验数据统计分析的基础上,选择克里格算法,通过变异函数拟合,结合矿山生产所揭露的矿石品位分布情况,确定合理的估值参数,以矿体实体模型为约束,建立了与生产认识基本相一致的矿石全铁品位分布模型,较好的反映了品位的分布特征,与开采现状模型相结合,为生产中出矿全铁品位的稳定提供参考依据。According to the metallogenic type and distribution characteristics of ore in the Sijiaying Iron ore, on the basis of statistical analysis of total iron assaying datum, chose Kriging method, through variogram fitting, combined with ore grade distribution situation revealed by mine production, some rea- sonable estimation parameters were confirmed. Orebody solid modelling as a constraint, TFe grade distri- bution model which was consistent with production knows is established. It can reflect the distribution characteristics of grade well. Combined with mining situation model, it provides reference for stable ore removal and TFe grade in production.
