Abstract :

Human needs always guide him to get use of natural resources. This usage causes damages to theenvironment and lands which are used by human. Human greatest need to natural resources is satisfiedthrough mining and making open – pit and underground mining. Due it is located near the surface andas it needs a great area to be demolished, open pit mining is very important from the view point ofenvironment. Regarding human necessity, demolished lands should be reclaimed in order to be usedfor post mining applications. Choosing a proper option for reclamation of mined-lands is veryimportant. First, the option should have economic income and second, it is comply with cultural andsocial criteria. Techniques of multi attributes decision making are used for choosing a proper option.This research is done on the basis of TOPSIS method which is one of the techniques of multi attributesdecision making, and through this method a proper option was chosen for post-mining application of atailing pond in an open pit mine. So, lumber production was chosen as a proper option for post-miningapplication of a tailing pond in an open pit mine.
