Design and Implementation of Prediction Analysis System for Coal Mining Subsidence Based on GIS

In order to efficiently and accurately predict the scope and degree of the coal mining subsidence，analyze the damage degree of the mining subsidence to the surface and buildings，in this paper，the design principle of the prediction analysis system for the coal mining subsidence was proposed，the information flow of the system was analyzed，the spatial database and the main function modules of the system were designed，and the key technologies of the subsidence prediction model based on masonry beam structure and the subsidence prediction model by the probability integral method based on the coupling of loose layer and bedrock were designed and implemented．The coal mining subsidence prediction system was developed by using GIS component，which better realized the map management，the information extraction，the calculation of the subsidence prediction model and the analysis of subsidence damage degree．
