Developing of mining areas should comply with sustainable development principles so as to ensure sustainable development of mine, to unify social, economical and the ecological efficiency. The selection of reclamation method is a complex multi-person, multi-criteria decision problem while sustainable development challenges facing the minerals and metals industry need a comprehensive and interdisciplinary approach based upon reliable data and transparent methodical approaches. The aim of this study is to propose a combined Multi-Criteria Decision-Making approach (MCDM) to evaluate the post-mining land-use methods with the use of effective and major criteria in respect to the user’s preference orders. In this paper, a Mined Land Suitability Analysis (MLSA) framework containing fifty numbers of leading evaluation attributes and also eight possible groups of post mining land uses for a mined land is used. This study utilizes entropy, weighted least square and AHP techniques to obtain the relative weights of attributes. Once the global weight vector of the attributes is calculated using these three methods, they are incorporated into the decision matrices and passed to the ranking techniques. SAW (Simple Additive Weighting), TOPSIS (Technique for Order Performance by Similarity to Ideal Solution) and Compromise Programing are used for ranking the alternatives. In other words the post-mining land-use methods ordered with nine ranking procedures. Due to specific approach of each of the above methods, and their advantages and disadvantages; the set of orders are not the same and for further aggregation, three ordering techniques employed to final ranking of the alternatives. Based on the statistical analysis two ranking methods excluded from nine procedures and average aggregated approach employed to rank the options. This procedure has been used for ordering the post-mining land use methods in a hypothetical mine. Accordingly construction of the mined land is the most appropriate method for the hypothetical mine in this article.
