中文摘要: 以国产DIMINE三维矿业软件为基础,系统收集整理了白音诺尔铅锌矿南矿段1号矿脉群750~800 m中段地质勘探资料,通过建立地质数据库,系统建立矿岩三维模型、数据的分析与处理以及资源储量估算整个流程,对比矿体与围岩模型特点、普通克里克估算方法与应用特点,研究结果表明:圈定矿体5条,模型显示矿体主要赋存在闪长玢岩与结晶灰岩接触带上,属典型的矽卡岩型矿床,空间展布形态呈囊状、大脉状、透镜状,整体北东走向;依据地质统计学理论,拟合求得理论变异函数应用于普通克里格估值,分别估算控制和探明资源量合计18.66万t,Pb+Zn品位为4.04%;与传统方法相较,普通克里格估算误差均在合理的范围之内,应用效果良好,估算精度高,可为矿山采矿设计提供参考,为实现矿山的数字化提供重要的理论依据。
Abstract:Based on the domestic 3D mining software DIMINE, the geological exploration data of the 750~ 800 m level section of No.1 vein group in the South ore section of Baiyinuoer Pb-Zn mine are systematically collected and sorted. Through the establishment of a geological database, the three-dimensional model of ore and rock, the whole process of data analysis and processing and resource reserve estimation are systematically established, and the characteristics of the ore body and surrounding rock model, ordinary Kriging estimation method, and application characteristics are compared. The results show that five ore bodies are delineated. The model shows that the ore bodies are mainly located in the contact zone between diorite porphyrite and crystalline limestone which is a typical skarn deposit. The spatial distribution shape is saccular, large vein and lens, and the overall NE trend. According to the geostatistical theory, the theoretical variogram obtained by fitting is applied to the ordinary Kriging estimation. The total controlled and proved resources are estimated to be 186 600 tons and the Pb+Zn grade is 4.04%. Compared with traditional methods, ordinary Kriging estimation errors are within a reasonable range, with good application effect and high estimation accuracy. It can provide a reference for mine mining design and provide an important theoretical basis for realizing mine digitization.
