Abstract：Aiming at pressure difference between the inner dumping and repeat stripping of adjacent open pit coal mine, variation trend of the boundary stripping ratio was analyzed. The judgment criterion of reasonable stripping ratio was determined for total inner dumping covering end slope. Based on the examples of Heidaigou and Haerwusu open-pit mine, the triangle coal recovery width should be 209. 3m for Heidaigou Open Pit Coal Mine in 2015.
