Software Architecture For Digital Mine Based On WebGIS

In recent years, with the wide application of computer information technology in the digital mine, some compartmentalized software systems on data collection, data processing ,computer graphics and others are formed in the various departments of the coal mine .But these systems can not interconnect and form the "information island." How to eliminate these "information islands" to establish an integrated application is the urgent needs in the digital mine construction. Therefore this article will combine GIS technology with the coal mine virtually to research software platform for digital mine, which has important practically significance in improving the informatization level and the digital mine construction.First, a variety of professional data involved in the process of coal production are analyzed in detail in this thesis. Data relationship between the various production sectors are clarified, and some data models are set up about survey data, ventilation data, electrical and mechanical data, monitoring and control data , production data, sales data and personnel data. So the establishment of digital mines system integrated project based on survey data is proposed to achieve mine multi-source and sharing of heterogeneous data and resolve the information sharing among various sectors in construction of the digital mine.Second, based on analyzing thoroughly the spatial database and the key technologies and theories of WebGIS, this thesis combines the characteristics of spatial data and the actual requirements to construct the digital mine software architecture based on WebGIS, which uses the object-relational database PostGIS and the open-source map server software GeoServer. Finally, the structure of the system is verified by taking the data in various departments for example, and the work on this paper are summarized and prospected.
