The invention belongs to the technical field of three-dimensional geologic modeling, and particularly relates to a three-dimensional geologic model construction method based on multi-
source data fusion, and the method comprises the steps: 1, extracting drilling data, and constructing a drilling
database; 2, constructing a topographic and geomorphic surface model, and completing the fusion of topographic and geomorphic data and drilling data; 3,
coupling information of strata, rock
mass, fracture, ore body and the like, and constructing a geologic body comprehensive model; 4, extracting geophysical and geochemical data, and constructing a geophysical model and a geochemical model; and 5,
coupling the borehole
database, the
landform surface model, the geologic body comprehensive model and the geophysical model, and constructing a multi-
source data fused three-dimensional geologic model. The method improves the
accuracy and precision of the three-dimensional geologic model, improves the
data processing and analysis speed, improves the
data analysis capability and depth, provides
technical support for
uranium resource
potential analysis and prediction exploration, and guides
uranium exploration.
