The Design Of Database Management System For Coal Mine Geological Survey Information

Along with the concept coming forth of "Digital Earth" and the development of corresponding technology, the concept and the whole frame system of "Digital Mine" and "Digital Coal Mine" have been put forward by some experts. The base of "Digital Coal Mine" is the management for geological survey information. The geological survey information of coal mine is concentrated reflection of "Digital Coal Mine", which is very important basis of the manufacture and management of coal mine. However, most coal mine in China always use general means to manage the geological survey information, which has baffled the development of coal mine greatly. Therefore, using database technique, assistance graphics and the space data analyze technique in the work of coal mine is the urgent mission at present. This thesis based on the analysis of coal mine geological survey system, designing the database of coal mine geological survey information as a whole,building the database integrallty, and implementing the function of operating the database. Furthermore, author integrated the vectorgraph technology and database, the program can draw the ichnography of coal mine automatically and query the information of geological survey by point selecting or in rectangle, circular and any polygon drawed by user on the ichnography. The system also includes some calculation and output function, which enriched the use of program. This design based on the Windows platform, handled the database theory, used ODBC technology and Visual C++ language. At last, the program had been proved applied by the WangShiWa coal mine geological survey information in TongChuan.
