基于球状模型的变异函数在拉拉铜矿矿体结构中的应用

摘要

The Lala copper deposit is located in Huili area,Sichuan province,is one of the typical IOGC-type large copper deposits in the Sichuan-Yunnan metallogenic belt.Taking DIMINE mining soft-ware as the experimental tool,based on the geostatistics theory and variogram,the practical data of the Lala copper mine is analyzed in depth,the experimental variogram is computed and the theoretical vario-gram is fitting,the mineralization characteristics and the basic spatial distribution regularity of the copper ore-body of Lala copper mine are analyzed.The research results in this paper can provide reference for the deposit reserve estimation and deep prospection work in the mining area.%四川会理拉拉铜矿为位于川滇铜多金属成矿带上典型的 IOGC 型大型铜矿床之一。以 DIMINE 软件为操作平台，以地质统计学为理论基础，以变异函数为核心，对该铜矿的勘探数据进行了统计分析，对试验变异函数进行了计算，并对理论变异函数进行了拟合，揭示了该铜矿矿体的矿化特征，分析了矿体基本的空间变化规律，为矿床储量估算及开展深部找矿工作提供依据。
