摘　　要：论述了应用地质统计学法进行露天矿勘探网度优化的基本原理和方法。以某露天矿为例,建立了该露天矿的矿床模型,得出了该露天矿主采煤层的煤层厚度、灰分和硫分等地质变量的理论变差函数模型,并对其变异规律进行了分析和评价。根据估计方差是勘探网度和网型的函数这一原理,模拟得出了最佳勘探网度,并对该露天矿首采区和后续区的勘探网度进行了优化和评价,为采矿设计提供矿床地质条件的可靠性论证。The basic theory and method of applying Geostatistical Methods in optimizing the exploration gird was discussed . The coal bed model and theoretical variogram model of geological variables of an open pit mine was established using Ordinary Kriging Method, one of Geostatistical Methods. The variance laws of thickness, ash content and sulfur content of main coal seams were analyzed and evaluated. The optimum exploratory grid was determined and the exploratory grid of the first mining area and succeeding area was also optimized and evaluated.
