Study Of Coal Reserve Management Information System Develops And Applies Based On WebGIS

The coal is important natural resources, which is playing the vital role in our country economic development.The coal resource reserve's informationization management is important technological means in the reasonable development coal mine and the highly effective use existing coal mine resources. At present, the coal reserve management method is unitary, the management level to be backward, many coal mine enterprises are only restricted in paper-based data management, has not used the computer in data management, some storage management software does not use geographic information system technology and network technology, not only causes the reserve data and the graphic of reserve comes apart seriously, moreover caused the zones of different coal reserve data sharing has created inconveniently, the key solved these question is the research and development based on the WebGIS coal reserve management information system.The geographic information system (GIS) as the mature graph and the data integration managerial technique has been widely applied in various domains. It changed the traditional graphics management and material data management pattern, its formidable spatial analysis function and the mass data management capabilities becomes important technological means of now the spatial data management. With the network and the database technology increasingly powerful which provides a better development platform for the development of GIS technology.Take the GIS technology, the networking and in the data bank technology into coal reserve management, will certainly to enhance the working efficiency of coal reserve management ,rich coal reserve management method and accelerating the process of building the digital mine. According to the coal resources management in the coal resources department and the state of discrete distribution of coal enterprises, proposed based on the B/S (Browser/Server) structure's coal reserves long-distance management pattern, the development platform of WebGIS by ArcGIS Srever 9.3, using the presentation layer, business logic and data layers to develop three-tier architecture to achieve remote viewing and storage of data storage.This article has analyzed the coal reserve management present situation and the trend of development, and has done the thorough research to the current existence's question and the corresponding solution in the first. Then coal reserves management information system technology base and development platform are briefly introduced.Based on this, take software engineering's design concept as the instruction, has made the detailed study on system's construction system and the functional module, and has carried on system's demand analysis, the system design and the database design. Finally, using coal reserves current data of Jizhong Energy Gequan mine for the experimental data to verify the function of the system. System realized the reserve maps zoom in, zoom, roam such as graphics operations, and coal reserves data, browse, inquire, add, modify, delete, and reserve calculations and aggregate reserves and other data management functions through the internet.
