The application provides a method and
system for predicting sandstone-type
uranium mine prospective areas based on GAT, and belongs to the technical field of
uranium geological research. By converting stratum unit data, sand body distribution data, structure line data, hydrogeological condition data and mineralization
verification point data into
graph node basic data and constructing a node
feature matrix, the prediction unit not only has its own geological properties, but also has scene
adaptation information for expressing the control degree. Then, by compatibility calculation of metallogenic relationship, low
control area metallogenic candidate channels and transition graph units are generated and graph structure data is formed, so that the prediction
processing process can express local spatial continuity relationship, sand body distribution relationship, underground water direction relationship, structure auxiliary relationship and low
control area channel relationship at the same time. Then, based on the node
feature aggregation processing of edge relationship features and attention coefficients, the neighborhood information contribution can be automatically adjusted according to the metallogenic relationship between the prediction units, so as to improve the identification ability of the concealed
uranium metallogenic prospective area.
