In China, the mine is facing a stern challenge over its environmental protection, the limitation on its structure and function within its subsystem, optimization of its limited manpower, financial and material resources and its sustainable development. Digital mine is come up with to deal with all these problems. The Digital Mine can be liken to “a logistics supply chain”, the basic characteristic is the high-speed network, with broadband and two-way communication system, used as “path map”, which shall make sure the fast delivery of all the data within all the relevant enterprises in the country; It consists of vehicles, which refers to the techniques of Mine CAD, virtual reality, mine simulation, scientific calculation, artificial intelligence, visualization and office automation; goods, which refers to mine data and mind application model; package, which refers to 3DGM(3-Dimensional Geographical Model) and data mining; security system, which refers to the collection and renewal system of mine data; and dispatching system, which refers to MGIS(Mine Geographical Information System), the common carrier of the entire information and office decisions, controlling the use and operation of all vehicles as well as all of the goods production and the package system. The basic structure of the Digital Mine is composed of two parts: digital ground and digital mine. The digital ground is a management information system based on the EPR (Enterprise Resource Planning) and spatial information infrastructure and information system based on 3S technology and computer network. The digital mine regards the mine geology and surveying data as basic information data for spatial positioning, furthermore, inputting other relevant information if necessary, such as mining working-face, excavating working-face, underground chamber, mechanical and electronic equipments, ventilation and safety device, underground pipeline and communication and others, forming a spatial database. Thus, the entire mine’s information system of management and service and decision support system is established. The Digital Mine is a huge systematic project, involving 3S (GIS, GPS, RS), IT (Information technology), mine science, virtual reality technology and visualization technology. Based on computers and network communication, the Digital Mine realizes the digitization of storing, transporting, expressing and applying of all the relevant spatial data and attribute data, including mine construction, exploration, development, mining, environmental protection and control. In addition, it is also a huge artificial intellectual system that integrates digital construction, digital exploration, digital mining, digital environmental protection and digital forecasting based on data dictionary technology, data warehouse technology, WebGIS, virtual reality technology, multimedia technology, CASE technology and artificial intelligence technology.
