Abstract: At the conditions of internal dumping and non-internal dumping, six homogeneous slope models and the slope model of the 1st Yimin open pit are founded, and solved these model’s angle of the end wall by FLAC3D program. The analyzed results demonstrated that the internal dumping can increase the maximum stable angle of the end wall in open pits at the same safety factor. So, using the internal dumping can decrease the waste volume or increase the ore’s production, reduce the stripping ratio, improve the mine’s economic benefit.

Key words: internal dumping, angle of end wall, FLAC3D, numerical simulation
