Abstract:

Mining and mineral industries are one of the main sources of environmental concerns for human societies. The process of mining and mineral processing of coal due to its nature and mechanism, has a high potential of creating different types of environmental pollutions. In this study, the Alborz Sharghi coal washing plant in Iran and its effects on the environment have been investigated using different environmental impact assessment methods (EIA). Initially, a list of plant activities and the environmental components have been prepared and after that three EIA methods include modified Folchi, AHP and RIAM matrix, have been used. Average results of expert suggestions show that factory waste water, toxic gases ans leaching from tailings with the score 8,7.9 and 7.9 respectively are the most hurmful activities of the company. The variety of the results of different EIA methods has always been one of the most significant challenges of the Environmental impact assessment. In current study, the results of various EIA methods have been coupled with each other by using some integration strategies like Borda, Copeland, Kemeny and Kohler. A novel strategy called DRS (Direct Ranking Strategy) have been developed in current research. The use of coupled environmental impact assessment (C-EIA) method to aggregate various EIA methods showed that the four components of "Groundwater", "Landscape", "Soil of the area" and "Ecology" are respectively the most critical environmental components of the Alborz sharghi coal washing plant.
