Research And Implement Of Open Pit Mining Scheme Analyzing And Decision Making System Based On GIS

In the process of production and decision making in opencast, technicians want to acquire decision supports to improve production efficiency and reduce costs. In recent years some area began to improve their digital ability. But there is a lack of the ability of efficiency by using AutoCAD and manual manipulation. With the development of 3D Visualization and GIS technology made it possible to improve this situation.According to the actual requirement, this paper discussed the application of the 3D Visualization technology in the GIS system. By the means of using the technology of 3D Visualization, this GIS system for mine can show the geographical information data of mine in three dimension and made user understand and grasp the geological structures of open pit mine at any time. These features can provide a visual decision support to the user.This dissertation focused on the research and experiment work in the following aspects. First, the design and implementation of Opencast GIS System . Second, the 3D Geosciences Model of open pit and the corresponding algorithm . Third, discuss the implement of 3D Visualization technology to GIS system.At last,based on the research of the above topics. Opencast GIS system has been developed using OpenGL. The software has been applied to Wugang Daye Mine and obtained excellent effects.
