Three-dimensional Geological Modeling And Visualization Of Spatial Interpolation Algorithm And Its Implementation

This article is based on the work of Chengdu University of Technology Mathematical Geology Laboratory-Mineral Exploration and Evaluation of three-dimensional forecast information platform for the development and demonstration of the Geological Survey Project, combined with some understanding of the geological body modeling and spatial interpolation algorithm fromthe classification of the data model of the geological body start on the main body modeling method. Commonly used three-dimensional spatial interpolation algorithm are discussed in detail, and the Kriging algorithm theory is applied to a specific instance.Three-dimensional geological modeling for geological exploration and mineral resources research has been widely used. With the development of computational graphics and the continuous improvement of the geological modeling theory, the continuous development of geological work, the traditional2d profile method cannot have satisfied people the requirement of strata and geological information description. And people demand more and more tend to be more simple and intuitive. So the study of3d geological modeling technology is particularly important.Firstly space in the body model of3d geological modeling method are detailed described and classified, and the modeling, the main factors to consider when choosing a data model are summarized. At the same time, the principle of three kinds of commonly used spatial interpolation algorithm for parsing, and will generally only used in two-dimensional theissen polygon interpolation algorithm, is introduced into the three dimensional space are quite flexible. At the same time of kriging interpolation space grade has carried on the detailed introduction. Also to compare the advantages and disadvantages of the three. Finally combining the theory and examples, apply theory to hubei green mountain copper ore, here we see mines has collected some drilling data, and carries on the processing, will be processed after the point of kriging interpolation space grade, grade is the same or similar values of ore body by drawing method, it said. This, in turn, can on the specific grade of orebody distribution have a macro understanding, more at the back of the orebody reserve estimate is prepared, concrete scheme for mining decision.
