| Abstract: | In view of the research progress on current rock mass movement，the advantages and disadvantages of 7 predictions of the surface movement distortion is discussedCombining with some cases of coal mining project，FLAC3D numerical analysis method is used to forecast the surface movement rules and the distortion tendencyAnd its data are processed with the excel tableHence，its trend，the typical curve of dip section and the expression of rock mass migration parameter are determined，thus providing a reference for the prediction of the surface migration and the distortion in the actual project |
