阐述了应用地质统计学法进行勘探网度优化的基本原理及方法，以焦家金矿为例，利用大型矿山软件SURPAC建立了该金矿床的三维模型，结合钻孔和刻槽的样品数据，采用普通克里格法对金品位进行了估值及储量估算，形象地展现了矿体的空间赋存情况和矿石品位的分布情况，并对其变异规律进行分析和评价，模拟出最佳勘探网度，同时在该矿中深部中段进行了实际应用，为采矿设计提供了可靠的地质资料。

The basic principle and method of optimizing the exploration grid with geostatistics methods are discussed.Taking Jiaojia gold mine for an example,using SURPAC software establishes the gold deposits three-dimensional models,combining with sample data of drilling and groove,using the ordinary kriging methods to estimates gold grade valuation and reserve.Orebody spacing occurrence and ore grade distributions are showed visually,and their variation laws are analyzed and evaluated.Optimum exploration grid is simulated according to valuation variance function of exploration grid and mesh configuration.These methods are applied actually in the middle of the deep mines,and provide reliable geologic information for mining design.
