Abstarct: The main part of mineral expenses is affected by transportation. Saving fund in this part of mineral expenses – which is the largest expense part – can be a very good way to prevent sale price decrease, mine life increase and economical extraction. Therefore, it is necessary to minimize shipping costs, especially in the wagging sector. In this study, in order to reduce the cost of vector grabbing, the goal is to select the appropriate tailgate demolition site. In addition to the importance of each criterion, the opinions of experts are also different. Also, the superiority of options does not follow the zero and one rule. For this reason, Delphi fuzzy hierarchy analysis method has been chosen as the basis of work among decision-making methods. In this research, Golestan Iron Ore Plateau mine has been selected from two sets of mines in East K sheets, two main economic and environmental fields: the economic factors are: the distance between the dummies of the pre-processing machines, the smooth path, the failure The presence of mineral material in the tailings area by examining anomalous maps, the distance between the dropper and extraction pit and the capacity of the dummy. Environmental factors include: the absence of a dummy in the wind direction, the absence of an office building in the wind direction and the dummy, hydrological conditions and dust emissions. The options available in this research are 4 locations for waste accumulation. To solve this problem, the importance of each of the parameters is first measured relative to each other, then the importance of each option is evaluated for each criterion, and then in the next step, the rating of each option from the sum of the weight of each option is compared to the criterion in weight The same criterion has been achieved in relation to the goal. At the end, the dummy number 1 is chosen as the best option.
