With the large-scale development of the coal industry,the eco-environmental problems and social problems caused by mining subsidence is more and more sharp,people’s normal life and production activities have also been serious interference in mining area,at the same time, the economic benefits of coal mine also under the serious influence.Therefore, in order to reduce the surface damage caused by the coal mining,we must obtain the relevant strata movement parameters of the mining area,master the regularities of the subsidences. Through set up the surface movement observation station in mining area and deformation monitoring on the surface,to obtain the observation data,to calculate surface movement and deformation volume by the reliable mathematical model and adopt reasonable estimated method through the analysis of the observation results.In this paper,using Visual Basic language combined with AutoCAD,Surfer development the mining subsidence information processing system.Take GuBei1312(1) working face as an example, compiled the surface movement observation station design module. According to the geological and mining conditions of the mining area to design the observation of1312(1) working face,drawing floor plan of the observatory mining area. With comprehensive observation of the face and observational data of daily observation,compiling the automatic processing sub module of the observation points’s deformation and movement values,deformation and movement curve and subsidence isoline.Based on the theory of probability integral method,the method to calculate the surface movement parameters is studied under the condition of limited mining,damped least square method is studied,puted forward damped least square method,givend its calculation formula, and the sub module of the surface movement’s predicting parameter fitting method is compiled.After the surface movement parameters,making mining subsidence visualization by using the system.At the end of the thesism based on the theory of the rectangular working face’s probability integral method,the method for predicting subsidence is studied,under the cured surface an shape of face.The method of surface integration is introduced.The subsidence models for unit subsidence basin and uint level movement are established in three-dimensional space.The formulas for predicting the surface subsidence,incline deformation,curvature deformation,level movement,horizontal deformation are deducted.All softwares of the system are programmed,and are comprehensively tested by the test technique of computer.The calculated data are checked by the measured data,and also the results on the test and check are satisfactory to us for the design and engineering requirements.
