The Research On CAD System Of 3D Geological Survey

With economic development and CAD technology's constant perfection and popularization, automatization level of mine enterprise designing and management for manufacturing has already become important standard of measuring its manufacturing level and modernized degree. Geological surveying and mining as basic component of mine enterprise designing and management for manufacturing naturally become an important part of mine enterprise's automation construction. But the operation mode of manual designing and management via drawing materials and sets of account materials can't meet the need of designing and management for modernized manufacturing, restricting the development of mine enterprises. So, setting up CAD system of Geological survey is the basic task of enterprise's automatic construction.CAD system of 3D Geological survey researched in this paper is an important part of Beiminghe iron ore enterprise's automatization construction This paper research for manufacturing designing and management of Beiminghe iron ore enterprise which is its actual application background. Aiming mainly at the application of CAD technology in Geological survey as well as providing complete geology materials for mining designing, This paper has discussed and studied several pieces of key technology and method involved in design and realization of software, whole structure as well as selection of development tool and environment of software and so on.From the practice of engineering application, this paper carries out the following items: Accessing structure of Geological survey data as well as mutual transforming technology with its graphics. The theory and method of automatic drawing boundary line between ore and rock based on the artificial neural network. The theory and method of automatic modeling 3D mineral deposit model based onOpenGL technology. The predicting and analyzing model of Geological survey data based on Rough Set.This paper has comprehensively used advanced ObjectARX technology, Database technology, OpenGL graphics technology and ADO technology. Using Visual C ++6.0 as the developing platform, AutoCAD as the application platform, MSSQL Server as the database platform, this paper has accomplished whole design of system and realized the software. The whole software system can run well and use conveniently in AutoCAD, with a friendly interface and a better functions between operator and computer. This makes the process of design for Geological survey and mining less dependence on user's specialty and experience, and makes design result better in quality, faster in speed. All of these embody the great priority of the CAD system of 3D Geology and Survey even more.
