摘　　要：山东归来庄金矿床是鲁西地区最大的构造—隐爆角砾岩型金矿床,矿体具膨胀狭缩、分枝复合等特征,产出形态变化多样。为直观反映金矿体的空间分布特征,对资源储量便捷化精细化管理,实施矿山信息化建设,利用Micromine软件成熟强大的数据库技术、三维建模技术和地质统计分析方法等,通过收集钻孔等数据信息,在Micromine软件中建立了地质数据库,根据资料信息对矿床三维地质实体模型进行了可视化构建,并采用距离反比加权法对主矿体进行资源量估算。与传统地质块段法计算结果相似,估算结果可靠。The Guilaizhuang gold deposit is the largest structure-hidden,explosion breccia-type gold deposit in western Shandong Province.The ore body displays various characteristics including expansion,narrowing,and branching,resulting in complex and diverse formations.To better understand the spatial distribution of gold ore bodies,enable precise resource management,and improve mining operations,researchers established a comprehensive geological database using Micromine software.This database combines borehole data with other relevant geological information,integrating advanced database technology,three-dimensional modeling techniques,and geological statistical analysis methods.Using this compiled data,researchers created a 3D geological model of the deposit and estimated the resource quantity of the main ore body using the inverse distance weighting method.The calculated results align closely with those obtained through traditional geological block methods,confirming the reliability of the estimates.
