Abstract: As one of the core contents in the digital mine construction，new methods of orebody three-dimensional modeling have emerged continuously in recent years.Three-dimensional modeling methods are summarized around six aspects such as data sources and data interpolation of ore-body three-dimensional modeling，surface element modeling，volume element modeling，hybrid and integration modeling，automatic modeling and model dynamic update.The results show that：① drilling data is the most widely used in three-dimensional orebody modeling.The focus of the research is how to add virtual drill hole based on limited drilling data and how to attribute interpolation to the orebody volume element.② Connecting contours of geological section along exploratory line is mainstream surface element modeling method，which involves three key issues including contour corresponding，contour veneer and branch processing；③The main study direction of the volume element modeling are modeling efficiency and accuracy，constructing the new topology to better achieve the model cutting，splitting and spatial analysis and the expression of complex geological structure; ④ The study on hybrid and integration modeling usually focuses on modeling efficiency and accuracy.The researches on orebody data redundancy and consistency problems in the hybrid model，ties and topological consistency problem of integration model can rarely be found，which has restricted the promotion and application of the model; ⑤ Automatic modeling and model dynamic update are the most challenging research direction，which relates to the vitality and the utilization potential of the model.The related researches are still in its initial stage of exploration at the moment.
