Management And Processing Of Mining Subsidence Movement And Deformation Based On ArcGIS Engine

With the mining of underground coal in the mining area,the initial stress in the rock formation is destroyed,resulting in movement and deformation,which in turn affects the surface,causing the surface to move and deform,resulting in damage to the living facilities of the surface residents in the mining area and changes in the ecological environment.In order to grasp the movement and deformation of the surface of the mining area in real time,it is necessary to collect regular field data,and guide the work of the mining area according to the movement and deformation of the surface.This paper chooses C#programming language,uses SQL database language as auxiliary development language,and realizes management and processing analysis of mining subsidence movement and deformation data based on secondary development of ArcGIS Engine.For data management,make full use of the advantages of database technology in data management,provide data management support for secondary development software,raw data collected by foreign industry,coordinate point elevation data of control points after internal processing,and data such as surface movement and deformation The preservation and management of the database;for the surface movement and deformation curve file,the software interface under the recursive algorithm is managed and applied by the directory structure.For the processing of surface movement and deformation data,considering the compatibility of the results with other software,the commonly used Shapefile data file format in GIS is used to draw the surface movement and deformation curve.Based on the model of probability integral parameter inversion method,the accurate probability estimation parameters of mining area are obtained,and the quantitative relationship model between probability integral parameter and surface subsidence is established.The method of probability integral parameter inversion based on template vector method is proposed.And realize the solution of the surface movement deformation parameters.The overall software development includes the implementation of common functions in GIS software,including opening files,attribute query,feature selection,bookmark editing and other functions.Based on the mining movement and deformation data of Zhujidong 1222(1)working face,this paper verifies the practicality of GIS common functions such as data management and surface movement and deformation curve drawing.The overall interface of the software is simple and easy to use,and the results are drawn.It can be compatible with other software,and expands the acceptance surface of the result;the parameter obtained based on the parameter inversion method of the model vector probability integration method,the error in the direction of the sinking direction is between 50.80mm,and the error in the direction of the line is Between 61.45mm,the predicted value of the inversion is roughly consistent with the measured value.Figure[24]Table[10]Reference[52]...
