变异函数在广西大厂锡矿田X号矿体中的应用

Application of Variogram in the Reserve Evaluation of An Orebody of Dachang Tin Deposit in Guangxi

变异函数是地质统计学的核心内容和基本工具,它能够较好地研究一个矿床的区域化变量的基本特征,特别是能够反映变量的随机性和结构性的变化牲。在对大厂某矿体地质特征进行研究后,计算了该矿体的变异函数,并且对计算结果进行了分析。结果表明,利用变异函数建立矿床数学模型进行矿体储量估算是一种切合实际的方法。

Variogram is the core content and basic tool in geostatistics. It can well reflect the basic characteristics of the regionalized variables of a deposit, especially their random and structural change. Based on the study of the geological characteristics, the variogram of this orebody is computed and the computation result is analyzed. The result demonstrates that it is a practical method to use the variogram to establish a deposit mathematical model for the evaluation of orebody reserve evaluation.
