Three-Dimensional Geological and Mining Modelling Based on Multisource Data

摘要

Three-dimensional geological and mining modelling in mining area is important for mine enterprises more productive, efficient, safe mining. Based on the available data such as cross-sections, drill-holes and geological maps, we developed to process geological information for building 3D model in this paper. Thus, special attention has been given to data structures and processing flows. Firstly, data arrange and sort with Geodata base in ArcGIS, secondly, the 2D theme information is analyzed and stratigraphic is classified using geostatistical analysis method, thirdly, with the above pre-processing, the 3D model of Zhangji mine is built with 3DGeoModeller software. The results show that the overall 3D geometry of stratums below Zhangji mine (mainly coal seams) and the relationship of formations are then presented, the coal seams modelling and the theme information which suggests the presence of a relatively spatial distribution are analyzed, modelled geology on section is compared with the corresponding measured section. The 3D model built with multisource data is thus compatible with the geological data. The method is suit for 3D geological and mining modelling.
