3D Geologic Modeling Of Mines Based On 3DMine

Our country possesses rich mineral resources. In order to make full use of mineral resources, promote the rapid development of China’s economy, It is very important to establish a complete system of mine 3D geological modeling. However, in the process of the mining 3D geological modeling, the most important work is to do good in construction of digital and physical model to mine. Therefore, the "digital mine" has become a research hotspot, and it is the core part of the mine mining and production.This paper analyzes the domestic and foreign mining and Research Situation of three-dimensional modeling software, the characteristics of data sources and data of the 3-D models of mine is discussed in detail. In the building process of mine database, the drilling data tables, geology tables, survey, sample tables are considered as the main part. Building the mine geological database, and in the discussion of the method of the three- dimensional geological modeling of mine, we depicted the building method of the terrain model, the ore body model and the laneway model separately. Based on the theories above, using 3DMine software as the modeling tool, constructing the mine geological database as the data source, a 3-D modeling experiment was carried out by using a metal ore and coal mines. Firstly, we analyzed and processed the drilling data information, designed the structure of the tables and input the data. Then, the ODBC registering data source is used, and the database was successfully connected to the 3DMine mining software, the drilling information was successfully displayed in the property window. Finally, with the use of topographic map or the scatter data files, the ore-line data files and the laneway midline or the wire mesh data files, using the modeling tools in the software, we constructed the drilling model, the strata model, the surface model, the mine model and laneway model.Finally, realize the construction of terrain, ore body, roadway model in the mine 3D geological modeling process under 3D Mine software, use for visual display of mine underground geological stratum structure, providing auxiliary decision-making for mine development.
