Research on Three Dimensional Geo-science Modeling in Digital Mine

摘要

The three dimensional Geo-science modeling (3DGM) is one of the core techniques in the implementation of digital mine (DM). The paper analysis the research status about the 3DGM in DM from two aspects: the data model and the software development. Combined with the research situation, the author discusses and simulates the 3D complicated geological interface modeling, the 3D complicated geological entity modeling and the 3D crossed tunnel modeling based on the Sub-area Dividing Thoughts, the Component-based Topological Data Model(CTDM) and the Symmetric-modeling Approach. Finally, the existing problems were summarized and the corresponding countermeasures were prospected.
