Abstract: To accurately predict the mining subsidence value of the coal mining working face,rational arrangement of the mining area,reducing the damage of ground movement caused by underground coal mining,predicting principle,predicting model programming and algorithm of MSDFVS(mining area ground surface deformation forecast and visualization system) based on MapInfo has been introduced in detail.The correctness and rationality of the system is verified by an example.The results show that the system not only achieve prediction of the static and dynamic subsidence on single working face or multiple working face,but also achieve the 2D,3D and dynamic visualization of the prediction result,which has a certain significance in surface subsidence prediction and control,"three-under" mining and other aspects.
