The 3D (three-dimensional) modeling has become an important digital and information technology with the continuous progress of science and technology, and it has been widely used in the ore prospecting, especially the uranium ore, which is an important strategic resource for the development of our country's nuclear industry. In recent years, 3D digital modeling technology has become a mainstream method in the geological industry with the rapid development of prospecting and prediction methods, and it plays a huge role in prospecting and prediction research for uranium deposits. In order to strengthen the prospecting prediction research of uranium deposits in the Xiangshan uranium ore field, a three-dimensional digital modeling study was carried out in this paper. Based on previous research of the metallogenic geological background, ore deposit characteristics and metallogenic regularity of the Julong'an uranium deposit in Xiangshan area, Jiangxi Province, a semi-automatic 3D digital and information modeling software, SKUA-GOCAD, was used to build topographic surface, structure stratigraphy and ore body models of the Julong'an uranium deposit in this paper. It can analyze the spatial distribution and geological morphological characteristics of each geological body in the study area using these digital and information models intuitively. Together with metallogenic characteristics, the metallogenic prospective area was divided using the 3D digital geological prediction model, and it showed that the prospecting potential for the Julong'an uranium mining area was great. From this research we can draw a conclusion that it has an obvious ore-controlling effect for the stratigraphy, structure and abrupt changing zone of interfaces of different formations. Meanwhile, the intersection region with the interface between the rock formations, the abrupt changing zone of the interface between different formations, and the intersection region of three interfaces are the favorable metallogenic areas. This research not only provided important prospecting ideas for the subsequent mineral exploration of uranium deposits, but also was beneficial to the next stage of ore prediction research in the Xiangshan area.
