Many production open-spaces and slopes is occurred during or after both production and overburden stripping in coal open pit mines. Under these different conditions sometimes slope stability problems in pit embakments may occur resulting loss of money. In this article the design principles and range of instability of such embakments are introduced. The purpose of this study is to exhibit the methods of field rehabilitation and measures taking in to consideration against possible slope instability.

Mining sector, is closely related to natural environment, is different from other industrial operations. Many production open-spaces and slopes is occurred during or after both production and overburden stripping in coal open pit mines. Geometry of these open-spaces and slopes depend on overburden thickness, gratness of operation area and selected open pit technology. This, use and reclamtion of the area, is very significant for environmental assessment. The alternatives of different use for the area may be desing...
