Abstract: In view of the problem of the pressure difference between the inner dumping and the repeat stripping in the adjacent open pit, the change trend of the boundary stripping ratio is analyzed. The judgment criterion of reasonable stripping ratio of the total pressure to the inner dumping is determined.Taken the Heidaigou and Haerwusu open-pit mine as an example, through the analysis the Heidaigou’ width of the triangle coal recovery should be 209.3m.
