The Research On MGIS Of Rare-Earth Mine In Ganzhou, Jiangxi Province

Ganzhou, in Jiangxi Province, is rich in minerals and it deposits a lot of the rare-earth mine. However, because of illegal mine exploitation, emission of liquid and tailings pollution and Geological disasters happen frequently. Simultaneously, there are many serious problems in the mine development and management, as well as the information exchange, for example, lacking monitoring in the mine development, the underdeveloped informationization in mine exploitation, the low efficiency of mass data management, etc.RS and GIS as new technologies provide approach for monitoring the situation of mining and pollution, which enhance our mine management capability remarkably. The research used ArcGIS as GIS based-platform and developed the MGIS which based on ArcGIS Engine component by using C# language of Microsoft .net platform. It managed all of the spatial data through ArcSDE which is associated with SQL Server. To help users know the mine better, the author built an independent 3D scene module which used high-resolution satellite images of focus region. This module was refactored from the NASA World Wind which is an open source virtual reality system. The author put forward the data organization pattern in terms of mapsheet which optimized the data storage and accelerated the data query. The author designed the user interface in the Windows XP style by using Developer Express, so that the user interface represented more friendly and conveniently. In this paper, the author introduced and analyzed the data of the rare-earth mine in Ganzhou, Jiangxi province, and then expatiated on the database design and the function design according to user requirement and the characteristic of data. In the end, coding and testing for the MGIS was discussed.It makes the management of discrete data more perfect, the browsing of map more intuitionistic, the updating of information more convenience, that the mine spatial database involved all of the vector and raster data, as well as the development and the implement of the mine information system. It is also the efficient complement in the mine monitoring and the result of the combination of the GIS and RS. TheMGIS provides us with the rational management for the investigation and monitoring data, the application analysis in decision-making, as well as the data sharing. It enables people to know the mine developing situation. It offers the government and other related department the management platform of the mine information and basic data. It also improves the value and potential of the remote sensing investigation of the mineral resources development.
