AI Technical Summary

Technical Problem

Existing technologies are difficult to effectively express dynamic evolution in mineral resource prediction under complex geological backgrounds, have poor adaptability and limited interpretability, and traditional models lack scalability and generalization capabilities, making it difficult to meet the needs of refined prediction of deep and concealed mineral deposits.

Method used

A dual difference comparison between the three-dimensional ideal geological background field without mineralization interference and the actual geological background field is constructed. Combined with the theoretical response model of the interference coupling field, mineralization-related anomalies are identified through a voxel-level spatial coupling algorithm. A knowledge graph-driven interference factor system is used for intelligent matching and data integration to form a parameterized and spatialized mineral resource prediction model.

Benefits of technology

It realizes cross-validation of mineral resource prediction under complex geological background, improves the reliability and intelligence level of prediction results, adapts to the prediction needs of different geological backgrounds, overcomes the multi-solution problem of traditional methods, and significantly improves the flexibility and accuracy of the mineral resource prediction system.
