Compared with traditional two-dimensional geological data representation methods, three-dimensional models can fully and accurately express the boundary conditions of complex geological phenomena and various geological structures contained within geological bodies, intuitively reproduce the spatial distribution and interrelationships of geological units, and maximize the intuitiveness and accuracy of geological analysis. Therefore, 3D geological modeling technology has a wide range of application fields, including regional geological surveys, mineral resource exploration, mine design, mine production management, urban geological surveys and urban underground space management, hydrogeology, engineering geology, environmental geology, earthquake prediction, and many other industries that play a supporting role in the national economy.
