摘　　要：在贾家堡地质数据库的基础上,利用3DMine矿业软件进行样品组合,并对组合样进行地质统计学分析;根据分析后的矿体品位空间变异情况,运用距离平方反比法及普通克里格法对块体模型进行品位估值,并分别生成矿体资源量报告,比较了两者的储量计算结果,并探讨了在资源管理及采矿设计中的应用。Based on the geologic database of Jiajiabao, 3DMine software was used to combine sam- ples and analyzed them by geological statistics. According to analyzed ore grade spatial variation, inverse distance squares method and ordinary Kriging method were used to make grade estimation for block mod- el, then orebody resources reports were formed respectively. Two results of reserves calculation were com- pared, and application in resources management and mining design were discussed.
