| Mining Drawing is primarily designed to reflect the shape of the minerals, the geology structure, the mineral status and the layout of underground tunnels. Limitations in information storage and graph information of traditional drawing, causing the kind of information were not been updated and displayed immediately, which could not satisfy the demand of actual production and design.This paper is focus on visualization and integration technique for secondary developing mining CAD in order to achieve the dynamic interactive query system of drawing. After investigating the development trend of mining and the status of mining CAD, paper discusses the basic points as mining CAD structure, mining graph element collection constructing and its functions, mining CAD graph element attrib describing methods, mining CAD graph element database based on Graphics theory, database theory and visualization technology. It achieved the various inquiries between databases and mining drawing based on VB.NET, the inquiries effects is quick and visual. We can see different parameters in detail, which provide a reliable guarantee of safe production.Finally, JinJia Mine in GuiZhou PanJiang mining area as an example in the paper and it establish the dynamic interactive query system of CAD drawing completely. |
