1、附录 Digital mining construction（ Part） The introduction : Since the former vice President al gore in January 1998, in digital earth: how to understand our planet in the 21st century speech, first put forward the concept of digital earth and its framework, concept and practice of digital distributed i
2、n various specific industries and fields, the digital information technology is becoming more and more profoundly affects the development of human society. According to the national tenth five-year plan of the enterprise information requirement, must use informationization impetus to the development

GIS (Geographic Information System) is used for acquisition, modeling, processing, retrieval, analysis and expression of geospatial data in the computer Information System, spatial Information description, storage, analysis and output of the theory and method
4、 of a new cross subject. ? based on GIS platform. 1.1 The mine informationization present situation analysis in our country In recent years, our country mining industry informatization construction, although a larger development, but the overall situation is still not optimistic. In mine surveying,
5、planning, design, production and management informatization, the gap with developed countries is more and more big. As mine mine didnt put the information resources in one of the important strategic resources to plan as a whole development and comprehensive utilization of information resources to fo
6、rm more without adequate, stable performance of the system of the mine information infrastructure. In general the following problems: 1.1.1 Mine informatization overall level is low Our country is a big mining, mining industry is a labor-intensive industry, informationization level is low. In additi
7、on to a small number of mining enterprises have advanced a variety of information management system, most of mine is still in the early stages of information management, is not very good use of information technology to promote the development of the enterprise, the lack of overall planning, resulti
8、ng in the mining enterprises in the level of no good computer network infrastructure, no sharing of the network information data, also makes the mining enterprises in front of the knowledge economy dominated by information no advantage . 1.2.1 Most of enterprises focusing on hardware investment, has
9、 neglected the development, management and application of the software Most of the enterprise did not establish suitable for mining basic information database for the development of enterprises, the lack of perfect study coal mine spatial information system, the reserves of resources management syst
10、em and the 3 d geological model of system, etc., not formed a perfect mining software system. 1.3.1 Insufficient understanding of modern information technology Although the understanding of information mining enterprises compared with the past has improved to a certain extent, but with the national
11、information construction requirements to use information technology lead to the development of traditional companies such as mine has bigger gap. On the informatization construction, each also vary widely in mines, only someone who has a good efficiency, large scale, market concept and a strong sens
12、e of modern management of large and medium-sized mining enterprises of information demand is relatively strong . 1.4.1 The imperfection of the information resources management At present, part of the existing enterprise though have opened internal communication network, but the vast majority of ente
13、rprise web site is just a simple expansion of network, did not make full use of network to carry on the deep information resources development, the lack of sharing and networking of information resources, cant make the enterprise internal and effective information communication between enterprise an
