A Method of Spatial Analysis of Fault Structure Based on 3D GIS

Abstract:

3D GIS is a useful modeling tool, which can greatly improve the efficiency and accuracy of the geological modeling, meet the requirements of modeling in complicated geological area. A typical 3D geological model is composed of one or a plurality of stratum, structure, fault etc. In this paper, we divide geological body into blocks, determinate each levels block boundary, build single block model, couple them up in 3D space. Combining with variation characteristics of 3D geological body, by manual interpretation or second derivative method, we get their distribution characteristics of fault unconfirmed by drilling. Through 3D GIS visualization and space analysis, we can not only be facilitate to manage drilling data and visualize underground geological body, but also analyze fault characteristics from a real angle, confirm their boundary, get ore body distribution characteristics, and provide credible digital model for ore grade analysis.
