摘　　要：氧化-还原界面的分布在矿业生产及找矿勘查中具有重要意义。通过对北衙金多金属矿床万硐山矿段地质勘查、矿山地质和生产勘探等地质资料进行整理,对影响氧化-还原界面分布的因素进行了分析。经对比分析,查明地层、岩浆岩、构造、水文条件是影响氧化-还原界面分布的主要因素,褶皱对氧化-还原界面的变化没有影响。研究氧化-还原界面三维空间展布特征并建立较为准确的三维空间模型对生产计划的准确性及施工组织方案的确定具有重要意义,可实现资源的高效能利用。The distribution of oxidation-reduction interfaces is of significance in mining production and exploration.By organizing geological exploration,mine geology,and production exploration data from Wandongshan ore section of Beiya gold polymetallic deposit,the factors influencing the distribution of the oxidation-reduction interface were analyzed.Comparative analysis revealed that stratigraphy,intrusive rocks,tectonic structures,and hydrogeological conditions are the main factors affecting the distribution of the oxidation-reduction interface while folding structures have no impact on its variation.Studying the 3D spatial distribution characteristics of the oxidation-reduction interface and establishing a more accurate 3D spatial model are crucial for ensuring the accuracy of production planning and the determination of construction organization schemes.This allows for the efficient utilization of resources.
