Abstarct: Selection of suitable Haulage System method for minerals requires consideration from different perspectives; In order to do this, a large amount of data must be collected, combined, and analyzed in order to properly assess the factors that may affect the selection outcome; Therefore, depending on the type of function, the indicators should be combined with criteria in order to select the appropriate method. Considering that the purpose of this research is to select and design an appropriate approach for transporting coal concentrate from the East Alborz Coal Washing Plant to the destination, it has been tried to study the existing conditions in the region, effective factors and methods of transportation Provide an appropriate approach. The area in question is the distance between the East Alborz Coal Washing Plant and the Zarrinshahr train station. According to the research, the mentioned route has a length of 25 km and also the slope of the route is 2%, which is the slope towards the train station located in Zarrinshahr. According to the topographic reports, the region has very high elevations in different places. In this research, in order to select the concentrate transport method, first the operating effects of the current method are investigated and then the influential factors for selecting the transport method are investigated using the Fuzzy DEMATEL multi-criteria decision making technique. ..), economic factors (investment cost, preparation cost, etc.) and regional factors (topography, fault, etc.) have been selected. Then, with the criteria obtained from the Fuzzy DEMATEL technique, among the methods of transportation by truck, conveyor, compressed air and slurry pipe, using the multi-criteria Fuzzy ANP decision-making technique in two fuzzy states of the first type and the second type, The method of transporting the conveyor is selected. Finally, a conveyor belt with a width of 650 mm and a speed of 2 meters per second was designed, which has a carrying capacity of 200 tons per hour.
