     an increased demand for useful minerals, exhaustion of shallow-bedded resources, and development of machinery, enabling surface mining to be run deeper and deeper are a reason that the dewatering becomes a necessary condition for extraction in ever increasing number of operations. from the viewpoint of the necessity of dewatering and method of dewatering, several types of dewatering can be distinguished for surface mining operations. in such a situation, a dilemma arises to detect most suitable method of dewatering assuming technical applicability, economic efficiency environmental protection and so on. this paper being an attempt to develop a new decision support system based on fuzzy multi attribute decision-making method. an applied case study drawn from sechahoun open pit iron mine of iran is used to demonstrate and test findings. the proposed methods systematically evaluate alternatives, with the result indicating promise for solving a dewatering system detection problem.
