| In recently years, visualization, integration and intelligence in the field of CAD are a hot point for research. This dissertation is focus on visualization and integration technique for developing mining CAD system. The main content includes nine parts: Mining CAD system structure, Mine graph element collection constructing and its functions, Mining CAD graph element attrib describing methods and its characteristic, Mining CAD parameter graph element and self-define graph element constructing, Mining CAD graph element data model, Mine graph operation algorithms, Engineering database integrated with mining CAD technique, OpenGL visualization on mining CAD and visualization mining CAD system developing and its application.This dissertation discusses comprehensively the history, principle, method and practice of the mining CAD. Based on these studies, the author puts forward the module of CAD software system and its functions. By analyzing the mine graph elements, a seven-element graph collection for mining CAD have been established. The dissertation details the functions and characteristic of curves graph element, polygon graph element, character graph element, dimension graph element, parameter graph element, self-define graph element, and research comprehensively the methods describe and graph element attrib. After discussing the basic graph element collection, this thesis gives the description method, organization way, graph element visitation, save and load efficiency, suitability and so on of every element in the basic graph element collection in greater detail. The author provides a graph element data structure organized version which is length changeable and is a block storage record, and designs a new module of data, which can process both the geometry attrib and no geometry attrib of drawing element. Based on this, the data model of all kind of element is put forward. These data structure models are described by utilizing c++ language and are very suitable for processing mine graphs that have engineering meanings.Graph algorithm studying is a key for CAD system developing. In this paper, a lot of research works of algorithms of mining CAD has been done. Many important mine specialty graph operation algorithms have been put forward. The main results are as follows: polygons cut out algorithm, two close polygons mutual, merge and subtract algorithm, polygon vector fill, any vector polygons area calculating and sequence polygons or multifold which has the direction and region area calculating, curve smoothing, graph element search for any region, graph element attrib collect in any region, parallel polygon or vector intersection-point push out or pull in, ore reserves and grade calculating for any type polygon, mine spatial data searching and boundary line tracking and automatic link algorithm etc.It is the development trend that lEDB.in integrated with CAD. ThisABSTRACTdissertation discusses the mine engineering database integrated with mining CAD in great detail. The author provides an arrangement of mine engineering data into classes or groups according to graphics attrib or process methods, and build a data module for mining CAD software, which is a key for the integration of the deposit engineering database system and graphics system. Based on the classifying and organizing of mine engineering data, the author build a database structure of deposit model engineering database and graph core system, and developed a geology database system based on levels relationship, which can support both geometry attrib and no-geometry attrib, and it is suitable for multi-elements and complex types metal deposit.The dissertation summarizes the experience of developing the graphic system in mining CAD system. The author develops a visualization mining CAD system, which is based on VC++ and the graphics platform OpenGL. The software system includes geology database, open-pit mining module, open-pit mining & striping scheme, open-pit limit, mining computer aided design. In the end, a case study of Gaocu...
