Abstract: | The selection of an optimal reclamation method is one of the most important factors in open-pit design and production planning.
It also affects economic considerations in open-pit design as a function of plan location and depth. Furthermore, the selection
is a complex multi-person, multi-criteria decision problem. The group decision-making process can be improved by applying
a systematic and logical approach to assess the priorities based on the inputs of several specialists from different functional
areas within the mine company. The analytical hierarchy process (AHP) can be very useful in involving several decision makers
with different conflicting objectives to arrive at a consensus decision. In this paper, the selection of an optimal reclamation
method using an AHP-based model was evaluated for coal production in an open-pit coal mine located at Seyitomer region in
Turkey. The use of the proposed model indicates that it can be applied to improve the group decision making in selecting a
reclamation method that satisfies optimal specifications. Also, it is found that the decision process is systematic and using
the proposed model can reduce the time taken to select a optimal method. |
