Discussion on the application of GIS 3D system in mining industry

         With the rapid development of scientific and technological progress in China , send Geographic Information System The R & D results of new technology products are used by more and more manufacturing industries , The mine manufacturing industry has gradually begun to pay attention to the organic combination of GIS and mines . Our country's product research and development of mine geographic information system , It has achieved little success in theory and practice , But on the whole, in the practical application , The technology is not mature enough . If we can make a perfect combination of mine and GIS , That is, the geographic information system related data information in the computer is associated with the location of the mine itself , This is also of great positive significance to the social and economic development of this region .

1 The characteristics of GIS
         Geographic information system has diversity , For example, the most common and basic geographic information system 、 Land planning 、 Law enforcement, etc . This is also due to the purpose of each GIS 、 The main uses are different . But whether it is basic or professional , They belong to all aspects of GIS , So they all have the most basic components , Image data acquisition 、 Store 、 operation 、 Updating data and information are all indispensable .

2 The application of GIS in mine
2.1 The importance of using GIS in mines
         Although the mine is also a mountain , But it is very different from ordinary mountains , The key is reflected in these aspects ： The stratigraphic structure in the mine is obviously different , The geological structure is complicated , Hazards of surface water, etc ; There are various ways of operating lean production , When working , The total number of machines and equipment used is huge , The actual operation is complicated . Therefore, when carrying out mining and other operations in the mine , The resulting data information is also immeasurable , The content of this information is critical , Once lost, it will hinder the mining operation , It not only wastes time but also consumes money and material resources , Great damage . This must rely on geographic information system to store data information .

2.2 The application of GIS in mine
         Professional technicians are collecting the geographic information of the mine 、 carding 、 Storage 、 Analysis is inseparable from the technical support of geographic information management system . Expand the obtained data information into unified operation , According to the electronic information technology, the simulation model of the mine cross section , For technical professionals to analyze the overall planning , The application of the system software reduces manpower 、 The cost of material resources . Accurately analyze the actual geological environment data information of each coordinate of the mine 、 Economic development, development and design level 、 Highway slope surveying and mapping engineering and technical and other reference data information , So that the management of the company concerned can More direct 、 Quickly grasp the basic information , Including the reasonable layout of resources in each ore bed 、 Special properties 、 Resource quality and storage capacity, as well as the technologies adopted for safe development, etc , It will lay a foundation for the future development and design of mine resources and the basic construction of production lines .

3 3D visualization of Mine GIS
3.1 Creation of 3D scene model
         The establishment of three-dimensional scene model should be based on GIS Given DEM And liberal arts data information , And the side length, angle and height of the overall engineering building . The simulation scenarios are various , Take care of a lot , Most of them are created on the basis of 2D graphic design drawings .

3.2 The establishment of three-dimensional topography
         application Skyline The mobile phone software of series products is transformed into DOM And DEM Data information , According to the topological relationship between commodities, assets are reorganized and a high-level model is established , The mobile phone software that can be used in the production process is not necessarily the same , But eventually we have to draw .mpt 3D indoor space scene model in file format .

4 Maintenance mode of mine geographic information system
4.1 Input and output of data information
         Data information is composed of GIS The main elements of the system software , According to the different characteristics of data information, we can It is divided into two categories ： One is the common attribute data , Most are contained in text messages 、 Documentation 、 In the report , Use office software to record this kind of data information according to certain regularity , After detailed storage, the storage and enabling methods of transformed data information coexist GIS Database query in . One is the spatial data of GIS which is different from other system software , Map data information is based on mine visibility geological map 、 A general term for data information obtained by analysis in images such as contour maps , Intelligentize the information content into records GIS Database query can . natural , It is also necessary to establish the mine site Topology, The actual characteristics of the entry commodity .

4.2 Search and management methods of data information
         The double search of data information can Using mine models Topology Establish the search of indoor space , That is, from attribute characteristics to natural geographical patterns or from natural geographical patterns to characteristics . During the whole process of development and design of the mine , The content of information changes all the time . For more accurate management methods , Relevant survey personnel must add or delete GIS Data information in database query , Maintain the direct upgrade of mining information content . In general , The data information of the mine geographic information system should be synchronized with the specific development and design database , The fusion GIS Definition expertise 、 Applied technology and specific work experience , Maintain the unity of geographic information and data information output 、 Collection and arrangement 、 Analyze the visualization and automation technology of receiving inspection .

5 Conclusion
         According to the above , We must admit that , The integration of mine and GIS is the trend of the situation , The application of mine geographic information system will be more and more extensive in the future , The development potential will be very good . Because of the difficult geological environment of the mine , The landform is complicated , The scope is not too big , The emergence of mine geographic information system can Use a three-dimensional perspective , Clearly and vividly show the characteristics of the mine . At this stage, the key problem encountered by our research institute is the collection of data information and the need to directly upgrade the data information .
