[Abstract]:Through the three-dimensional visualization simulation of geological body, the geological structure and structure of geological body can be visualized, accurately and comprehensively expressed, which provides a digital tool for the study of geological body and opens up a new viewpoint of three-dimensional GIS research. At the same time, the program design of 3D geological body exploration and modeling also has certain reference significance to promote the development of digital mine. This paper is based on the National Geographic Information Mapping Bureau key Laboratory Development Fund project "Research on 3D Mine Modeling method based on IDL and Skyline", with 3D geological body exploration and modeling method as the core. The program design of geological body modeling is studied and realized independently. The results are as follows: (1) the modeling method of 3D geological body exploration is studied, and the borehole data is used based on interactive data language IDL,. The display of borehole histogram is realized. The modeling and integrated display of 3D geological surface model and solid model are realized by using IDL object model. At the same time, the interface with friendly man-machine interaction is designed, which can be used in the research of 3D modeling and visualization of geological bodies, and can be used to translate, rotate, zoom and other interactive operations to realize the cutting display and information acquisition. Texture mapping and other functions can effectively analyze the unknown geological information. (2) taking the modeling of Sunjiadun mine section as an example, the testing work of program design is carried out, which verifies that the design has certain practical value.
