摘　　要：毕机构钒钛磁铁矿床是陕南目前正在开发利用的钒钛磁铁矿床,矿体产出于辉长岩中,属岩浆分异—后期热液改造型钒钛磁铁矿床,本文以3DMine软件为操作平台,运用地质统计学法,通过数据整理—建库—半变异函数分析—普通克里格插值—资源储量计算等步骤,对毕机构矿床进行了资源储量计算,论证了合适的圈矿工业指标。充分体现了地质统计学法在复杂矿区资源储量计算过程中较传统资源储量计算方法表现出的优势和便利。The Bijigou vanadium titanium magnetite deposit is currently under developed and exploited in southern Shaanxi.Its ore bodies occur in gabbro,attributed to the type of magma differentiation and later hydrothermal reformation.In this paper,the 3DMine software is used as the operation platform.By ordinary Kriging interpolation,resource reserve calculation and other procedures,the reserves of this deposit is calculated,and the suitable industrial indexes of ore mining are proved.It fully reflects the advantages and conveniences of geostatistics in the calculation of reserves in complex mine areas compared with traditional methods for this end.
