An analytical approach with a reliable logic and a ranking policy for post-mining land-use determination

چکیده مقاله

Because it is the post-mining land-use that prescribes the methods, the measures and the costs of mine
reclamation, amajor implicit goal of mine reclamation is to determine an after-use option. Therefore, there
should be an analytical approach to optimize the determination of post-mining land-use. A Mined Land
Suitability Analysis (MLSA) framework, which had been previously derived from reclamation practice
reports of mines and other disturbed lands, is used in combination with two Multi-Attribute Decision-
Making (MADM) techniques to provide the required analytical approach. In the proposed approach the
decision makers consist of the most related experts and the identified stakeholders. The Analytical Hierarchy
Process (AHP)method is used to determine globalweights ofMLSA framework attributes via pair-wise
comparison matrixes composed by each individual expert. Once the globalweight vector of the attributes
is calculated using AHP, they are incorporated into the decision matrices composed by stakeholders
and passed to the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), which is a
distance-based MADM technique and is used to determine preference order of post-mining land uses.
