Technology Research On Filling Mining Method Computer Aided Design

In recently years, visualization, integration in the field of CAD has become a hot research topic, and the method of filling mining is the inevitable trend of mining developing mining CAD system. This dissertation is focus on visualization and integration technique for developing mining CAD system.Thesis aims to summarize previous research on the filling mining method based on the objectives and the main content of digital mine and combined modern visualization technology with Languang geographic information systems to integrate innovation. Using visualization, integration technology and methods to achieve mining production, design among all phase of information integration and visualization-aided design, research the content of data preparation, task decomposition, work flow and visual expression in the production process of filling mining method to develop process simulation computer adied design system.Thesis presented an overall structure of integrated visualization filling mining CAD system based on Languang geographic information system after analysis of the mining CAD research status, development trends and its existing problems. The technology of filling mining method was researched, based on it we proposed The design process of building wall filling mining method, the design process of up layering filling mining method, the design process of under layering filling mining method and the design process of cutting walls to filling mining.Thesis proposed a general model of graphic redevelopment of the mining CAD after deep study of the design of graphic element and digital mine visualization technology to solve the difficult problem of repeat reword because some calculation errors. This model provides transparency between the key points and the application program and provides transparency between two-dimensional data structure and three-dimensional data structure and the application program, enhanced code reusability and portability.The paper introduces the model implementation scheme. In the realization of the process, thesis proposed design algorithm of automatic annotation graphic element and pillar graphic element. Thesis gives their detail design and proven their feasibility through realization. This system can enhance the feasibility of design and the initiative of program implementation. It will fill domestic and international blank in the area of production process visualization.
