Coal is one of the most important sources of energy in my country.As the country's energy demand grows,the total consumption of coal resources will remain at a high level for a long time.However,in the process of coal mining,a certain degree of surface subsidence,surface structure destruction,ecological damage and other phenomena have been caused.Therefore,a complete set of mine mining subsidence prediction and visualization system is designed to provide a powerful tool for harmless coal mining.Traditional mining mining subsidence prediction and visualization systems are often localized.Although they can solve the current problems of surface subsidence prediction and visualization to a certain extent,they also have the disadvantages of relatively fixed system platforms and poor portability.In this study,the C/S(Client-Server)architecture is used to calculate the mining subsidence in the cloud server.At the same time,various maps for mining subsidence analysis are drawn locally,and cloud computing and localization are organically displayed.Design of a set of GIS-based mine mining subsidence prediction and visualization system.The work of this article mainly includes the following:This paper integrates GIS model,parameter inversion model and subsidence prediction model,and realizes the seamless integration of probability integration method and spatial data structure.Because different GIS data models have different methods and efficiencies in the processing of GIS spatial objects or phenomena,according to the characteristics of mining subsidence surface movement and deformation prediction and later analysis application and display,a suitable GIS model is combined with the prediction model to effectively implement the system Visual output.In terms of the design and implementation of the system,this article divides the system into two functional modules based on the C/S architecture.The expected functions of the system are implemented on the cloud server side using the PHP programming language.The visualization function of the system is realized at the local end using the C#programming language.Through the ArcGIS Engine component development technology and SQL Sever database technology,the system can generate contour maps and profile graphs of the predicted results.By establishing a digital elevation model,the subsidence can be generated.The three-dimensional stereogram of the value makes the result more intuitive.An instance 1242(1)of a mine in Huainan mining area in Anhui was used for example analysis,and an observation scheme was designed to obtain measured data.The predicted parameters were obtained through this system to predict and visualize the movement and deformation of mining subsidence surface.This paper designs and implements a mine mining subsidence prediction and visualization system based on the GIS platform.The prediction module is implemented through a cloud server,and the returned results are visualized on the local end.The integrated model applied by the system can realize the visual expression of mining subsidence prediction and prediction results,and provides a powerful tool for the prevention and repair of coal mining subsidence.Figure 46 table 4 reference 74...
