摘　　要： 结合露天煤矿区域化变量评价的具体情况，论述了地质统计学中变异函数的确定与拟合、克立格估值以及参数选择等基本理论和方法，介绍了GEO-EAS交互式软件包的主要特点和功能，提出了露天矿区域化变量评价的流程。最后以某露天矿为咧，建立了17#煤层厚度的理论半变异函数模型，对其变异规律和勘探程度进行了分析评价：绘制了克立格估值等值线图、渲染图以及方差等值线图，并对其空间分布和估值精度进行了评价。实践证明，该软件在煤层、煤质以及开采指标评价等方面具有广阔的应用前景。 Combining with the appreciation practice of regional variance, the basic geo-statistical theory and method of the variogram computation and model fitting, Kriging and option selecting are discussed. Afterwards, the paper introduces the principal characteristic and function of GEO-EAS interactive software package and puts forward the appreciation process of regional variables in an open-pit mine. At last, an instance of one open-pit mine is studied. The theoretical semi-variogram model of coal thick No.17 is established and the variable laws and exploratory degree is analyzed, the contour and rendering map of Kriged estimate and the contour map of standard deviation are produced and the spatial distribution of coal thick and the precision of kriging is evaluated. The practice shows that the prospect of the application of GEO-EAS in the appreciation of coal seam, coal quality and mining index is extensive.
