Data Management And Analysis System For Advanced Geological Forecast Of Mine Based On Cloud Service

Most coal mining locations in mines are in complex hydrogeological areas,the gushing water and water inrush disasters often occur during the excavation of mine tunnels.Therefore,during the tunneling process,advanced geological predictions are required to prevent safety during mining accident.At present,the advanced geological prediction in the mine adopts the transient electromagnetic method for geophysical prospecting.The collected transient electromagnetic raw data is processed and analyzed on the data interpretation soft ware and Surfer software for professional geological mapping,and the corresponding geophysical data is archived,classified,and traced.The lack of management platforms and systems for storage and storage is also not conducive to the later safety supervi sion and traceability of the mine.In response to the above problems,a cloud-based mine advanced geological forecast data management and analysis system was proposed,and a B/S architecture database system and mine transient electromagnetic data interpret ation software were developed.The transient electromagnetic method advanced geological forecast data management and analysis system developed in this paper is divided into two modules: data management and data analysis.The data management is completed by the B / S architecture database system,and the data analysis is performed by data interpretation software and Surfer software for professional geological mapping.Through the database system administrator,the data interpretation software and Surfer professional software are packaged and uploaded to the cloud storage system.The technicians log in to the client and download the original collected data and analysis software package to complete the data analysis task.On the administrator side of the system,user rights assignment and data grouping management are implemented.By assigning user operation rights to different data,the problem of hierarchical management of data is solved.By adding data categories on the administrator side,data archiving is classified.In addition,in the data interpretation software,writing a Visual Basic script program can realize the automatic import and export of cross-platform data.After the data analysis software completes the data processing,it automatically imports the data into the Surfer software to co mplete the data visualization,Strengthen the automated operation,and further reduce human error and impact.The development of the system is mainly based on the analysis and inversion theory of transient electromagnetic method,B / S architecture and MVC development mode.Mine transient electromagnetic data interpretation software is developed using C ++ language and MFC framework.When the transient electromagnetic raw data is imported,the data format decoding,smo oth processing of the track and point are completed.Through the Tee Chart control,the secondary field extraction of the transient electromagnetic field data,and the automatic and manual filtering of the secondary field signal can be completed.Through wi ndowed parameter settings and automatic data import procedures,data apparent resistivity calculations,time-depth conversions,and inversion images can be quickly generated.B/S architecture database system is developed using Java language and Spring fram ework.The system program development uses the MVC mode,which makes the program low in coupling,high in reusability,and high in modularity.In the authority management of the system administrator,the RBAC authority management design and Shiro security framework are added to realize the hierarchical management of data and strengthen the secure access of data.The system also adds support for the Spring Boot framework,which can achieve remote hot deployment of the system.During subsequent maintenance and upgrades,there is no need to suspend system services,which improves the ease of use and maintainability of the system.After the system development was completed,the application of the example environment was carried out.According to the comparative s tudy of the exploration results report and the specific tunneling situation,the system fully meets the expected engineering requirements and meets the engineering application standards.Although this system can meet the current needs of advanced geo logical forecast data analysis,with the development of industrial information technology,more new requirements will emerge in the future.With the development and application of 5G industrialization in China and the research and application of wireless transie nt electromagnetic meters,as well as stricter safety supervision of coal mining,the system can be connected to the data upload interface of wireless transient electromagnetic meters and the database of the coal mine supervision system Further strengthen the automatic operation and data supervision of mine advanced geological forecast.
