Study On The Integrated Management Of Coal Mine Resources And Reserves Map Library

Resources and reserves are assigned and changed in a specific location.Coal mine resources and reserves management is a typical geospatial problem,involving multiple user levels for a large number of multi-temporal scale drawings,ledgers and reports for business operations,which currently lacks a scientific and standardized data organization,resulting in low management efficiency.Based on an in-depth understanding of the meaning,content and methods of coal mine resources and reserves management,this thesis has designed and developed an integrated management system of coal mine resources and reserves database from the whole life cycle of software engineering.Combined with the actual needs of application field,relevant information of a mine is collected,processed and converted,the structural features implied in the data are analyzed and refined,and the spatial and attribute information of coal mine resources and reserves data are classified and reorganized and stored in the database centrally.The integrated management system of coal mine resources and reserves database contains five functional modules,each corresponding to a set of main page performance.System login and registration page,realizing user login,registration and role authority assignment.Resources and reserves basic information page,invoking AMap tile map service resources,mining project plan(table)dataset,coal reserves classification map dataset,realizing map browsing,basic controls,layer control and information query functions.Coal resources and reserves calculation page,call auxiliary parameter determination dataset,coal reserves calculation map(table),realize functions of block segment division,parameter determination,auxiliary calculation,result saving and symbolic expression,etc.Mine resources and reserves dynamics page,calling loss calculation chart(table)dataset,reserves loss volume history dataset,and reserves dynamics history data table,realizing the functions of coal mine resources and reserves loss and dynamics information entry,balance relationship check,data review,summary,and export.Mine three quantity management page,call three quantity calculation chart(table)to realize three quantity division,three quantity and three quantity recoverable period calculation,result saving,recoverable period reasonableness analysis and other functions.This thesis adopts a front and back-end separated development approach with a full set of open source technology solutions,using Postgre SQL and its spatial data engine Post GIS to store data,integrating Spring Data JPA and Swagger by Spring Boot project to provide data services,creating React project with Dva JS,Umi JS and Ant Design framework,using Open Layers to call the map service published by Geo Server,combined with Turf JS geospatial analysis library,completed the construction of an integrated management system for coal mine resources and reserves map library.System integration,system optimization and data maintenance instructions were conducted.A standardized and regulated process and idea is designed for coal mine resources and reserves management by technical means.To provide support for information sharing on the quantity,quality,distribution,loss and change of coal resources and reserves,as well as the rational mining and utilization of coal resources.This thesis has 33 figures,9 tables and 85 references.
