| Abstract: | the method of grey prediction and safety system is discussed in this paper.the grey prediction model and the displacement prediction s established and safety prediction theory is achieved by using matlab with the computer.The whole process of safety forecast is studied in detail;finally the theory is applied in engineering practice,and the conclusiong is made as follows：the GM（1,1）model GM（1,1）model of residual band applied in pit horizontal displacement prediction is feasible recently,and safety prediction accuracy can be achieved. |
