Modeling And Application Of 3D Mine Model Based On 3Dmine

China has abundant mineral resources,in order to make full and effective use of mineral resources and promote the rapid development of China 's economy,it is very important to establish a complete 3D geological modeling system of mines.In the process of mine 3D geological modeling,it is mainly the digitalization of mine and the construction of entity model,so "digital mine" has become a research hotspot,and it is the core part of mine mining and production.This paper analyzes the research status of mine software and 3D modeling at home and abroad,and discusses in detail the data sources and characteristics of 3D mine modeling.In the construction of mine database,drilling data tables,lithologic tables,diagonal tables and laboratory tables are the main parts.In the discussion of 3D geological modeling method of mine,the methods of constructing terrain model,orebody model and roadway model are analyzed and described respectively.Based on the above theory and method,using 3DMine software as modeling tool,the mine geological database is constructed as data source.The 3D modeling experiment is carried out by using the measured data of a certain metal mine and coal mine.First,the number of boreholes is carried out.According to the analysis and processing of the information,the design of the table structure and the input of the data,secondly,using ODBC to register the data source,connect the database with the 3DMine mining software successfully,and realize the display of the attribute information of the borehole information in the view window.Finally,through topographic map with elevation or scattered point data file,orebody line data file,roadway midline or traverse network data file,using the modeling tools in the software,drilling model,stratum model,surface model,The orebody model and roadway model are constructed.Finally,the solid model is optimized and validated,and the construction of terrain,orebody and roadway model in the process of 3D geological modeling of mine is realized by 3DMine software,which can be used to visually display the underground geological stratum structure of mine and provide auxiliary decision-making for mine development and construction.
