The invention relates to a gold mine three-
dimensional modeling and target prediction method based on multi-
source data fusion. Aiming at the problems of low grade and large burial depth span of the layered hydrothermal
gold deposit and two-dimensional limitation and
distortion caused by single-
source data existing in a traditional modeling method, a three-dimensional joint
database is constructed by integrating multi-
source data. According to the technical scheme, a three-dimensional joint
database is utilized,
earth surface, geological stratum,
fault occurrence and trend information is determined, and a three-dimensional
earth surface and structure model is constructed; based on an explicit and implicit combined modeling method, three-dimensional space distribution of two-long-spot rocks is determined, and a three-dimensional lithologic model is constructed; a structure-
lithology coupling constraint modeling method is innovatively adopted, and a three-dimensional grade model is constructed by utilizing an implicit modeling method under the common constraint of a structure model and a
lithology model; and finally, target area delineation is carried out according to the three-dimensional geologic model. Compared with a traditional method, the method has the advantages that the problem of
distortion of model construction caused by a single
data type is effectively solved, and accurate depiction of the ore body is realized. And the constraint of the cause mode on the three-dimensional model is highlighted, so that the target region delineation is more in line with geological knowledge.
