摘　　要：结合一个实际的铜铁共生矿床 ,对应用三维地质统计学方法研究矿床建模工作涉及的若干技术与方法。首先进行了合理而有效的样品组合计算 ,同时研究了该矿铜、铁样品品位的分布规律 ,通过交叉验证工作 ,得出了相应铁原样品位及铜的对数转换品位进行矿床建模的结论 ,并分别建立了这 2种元素的品位模型。然后对建模结果与实际矿床进行了比较 ,其结果表明了建模的准确性。最后得出了应用地质统计学方法进行矿床建模工作的一些有意义的结论和建议。In combination with a real copper-iron deposit,some techniques and methods concerning the study of deposit modelling using three-dimension geological statistics were studied. First, the calculation of a rational and efficient sample combination was made and the grade distrubution of the copper and iron samples studied. It was concluded through crossing verification that the iron grade of the original samples and the logarithmic transfer grade of copper should be used in deposit modelling and the grade models of both elements were established respectively. A comparision of the modelling results with the real deposit showed the accuracy of the modelling. Some conclusions and suggestions that are of significance to the deposit modelling using geological statistics method are made.
