摘要
熵函数是研究矿体在空间上非均质特点和程度的有力工具。文章探讨了在地质勘探时建立各标志值熵函数的方法,定义了熵函数特征值。以个旧锡矿若干矿体的厚度为例,讨论了熵函数在矿体厚度结构特征的对比、分类,厚度均值误差的估算以及指导勘探工程布置等方面的应用。
Entropy function is a powerful tool in studying the characteristics and extent of heterogeneity of ore-bodies in space.In this paper, the author approaches the methods of establishing the entropy function of the parameter values of ore-bodies during geological exploration, and gives the definition of the eigenvalue of entropy functions.Taking the thickness of several ore-bodies in Gejiu tin mine as an example, the author makes a discussion on the application of entropy functions for the comparison and classification of the texture characters of the thickness, and on the estimation of mean value error of thickness as well as the arrangement of exploratory projects.
