【摘要】 大姚铜矿是我国重要铜矿山,对该矿床的最大矿体之一Ⅱ 1号矿体进行了研究,在地质规律研究的基础上,收集了与该矿体相关的铜、银品位数据,建立原始资料数据库,并对所收集的数据进行了可靠性讨论;对9061件铜样品和4160件银样品进行了统计分析,结果表明,铜、银品位服从对数正态分布;铜、银共生相关关系为弱相关关系,需要分别建立其数学模型。计算了铜、银走向、倾向、厚度方向及平均实验变异函数,并进行了理论拟合和验证,结合矿体的地质特征对获得的参数进行了讨论。更多还原

【Abstract】 The Dayao Copper mine is a big important mine of China. This paper mainly deals with No.Ⅱ-1 orebody, one of the largestorebodies in the Dayao deposit. On the basis of the geology of this deposit, the original three-dimensional database has been established, including the grades of 9061 copper samples and 4160 silver samples. Through statistical analysis,it is concluded that Cu, Ag values are of logarithmic normal distribution. The correlationbetween Cu and Ag is weak. So, we established their mathematical models separately, calculated and fitted the experimental variogram of Cu and Ag,and finally their mathematic models are established.更多还原
