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.
