Information Management System For Coat Mine Base On Supermap Object

in the daily production of coal, drilling data occupy a very important position,including the roof information, strata information, and a series of geographicinformation coal geological data. These data in the moment there are a large partdepend on the hand-drawn and maintenance of professional geological personnelmines. On the one hand the high cost of maintaining the mapping, some drawings ofdisrepair, the need to re downhole survey, on the other hand, in the detection of eachinformation point and maintenance of drawings did not place. Therefore developed adrilling information management system based on Geographic Information System(GIS) for. Geography and geology staff can make the timing of sentinel survey ofgeographic data, and apply it to the collection, storage, management, operations,destructors, shown and described space. Coal industry in the past, because theinformation behind other industries, so for a long time and there is no such astandardized, professional information management system, so the establishment ofsuch a drilling manager can provide more accurate location information in there thefirst time figuring out when downhole conditions, access to first-hand geological andhydrological data, resulting in a more accurate and effective application.This paper describes the use of several aspects of the technology, the systemfeasibility analysis, functional design and algorithm design and implementation of adetailed statement of the development and implementation process of the system, theuse of SQL Server database and.NET technology to achieve a combination offunctional arrangements in advance, and also visited a number of the mine staff andgeological survey team, the coal industry’s demand for early and systematicdeficiencies made detailed improvements. While optimizing the existing algorithm,using a mathematical theory about the statistical analysis, greatly enhance the speedand efficiency of the whole database and server-side software.Specific studies are as follows: 1. The use of the central limit theorem and random number generation design32Bitthe RSA algorithm, used for system validation and authorization, to ensure systemsecurity.2. The use of multi-tree indexing algorithm significantly improves the retrieval timedatabase field to mine multidimensional complex hydrogeological data throughsystem testing may be required data in a relatively short time to retrieve.3. Presentation and analysis of a variety of database schema4..NET-related technical principles and applications, including a host of technical andintermediate language program running speed increase on the compilation.
