Abstarct: Waste dump site selection is an important issue that affected the mining operations cost and depend on three criteria consist of environmentally, economically and socially. The major aim of this study, is the waste dump site selection of Abbas-Abad copper mine, NE Iran. For selection the best waste dump location, one process (Fuzzy AHP) with one Geographical Information System (GIS) such as: fault, geology of the area (permeability), road, water, slope rate of the area, existent height and access way has been collected together. So, different criteria are weighed, that has been weight of access way 53.909, weight of existent height 0.104, weight of slope 25.487, weight of road way 6.640, weight of permeability value 3.457, weight of fault 10.399 and next has been evaluated in software GIS. After that area to 5 different potential divided: Very weak, weak, medium, high, very high. The small of area 195000 m2 has very high potential, limit space 196200 m2 has high potential, limit space 108080 m2 has medium potential, limit space 755800 m2 has weak potential and limit space 644300 m2 has very weak potential. The mine dump can be desighened with height 17 m with of optimal condition consist of three mentioned criterias.
