Abstract: 

Gotvand dam is the last dam on Karoon River near Shooshtar city in khozestan province in Iran. The body of this hydroelectric dam is designed by rock fill material with a clay core and a concrete spillway and needs more than 25 million cubic meters backfilling material. So it is necessary to find a good deposit to provide this volume of material.
In the other hand to construct the concrete spillway of the dam it is necessary to achieve a stable and suitable foundation on rock, 42 meters below the crest of the dam. Also it is necessary to stabilize the wall of the spillway. But the height of the spillway wall is more than 260 meters and needs more than 20 million cubic meters excavation to stabilize it.
So it seems that the best deposit of rock fill dam material is the excavation of spillway wall for both the above purposes. But as the spillway wall excavation has 700 meters length with an average of 100 meters width, 260 meters height and surrounded with a cliff in one side and a definite berms in the other side, so it is necessary to design the best method to excavate this amount of material. In the other hand by the schedule it is anticipated that the production norm will achieve to 500 thousand cubic meters per month. So it is necessary to present a suitable method statement. For this purpose different methods were proposed. Finally the best method statement is proposed was the excavation of each level of 15 meters with independent access roads. In this article the design and method statement of the excavation is presented. This method is carrying out without any problems.
