A Fuzzy-AHP Methodology for Planning the Risk Management of Natural Hazards in Surface Mining Projects

Surface mining projects are vulnerable to natural hazards (earthquakes, floods, soil instabilities, and epidemic crises) which constitute the primary source of risks affect operations. In framework sustainable planning development such projects, investigation risk impacts is essential for taking appropriate preventive measures before disastrous events appear in a mine. This paper proposes methodology assessment surface using triangular Fuzzy Analytical Hierarchy Process (FAHP) determination probability occurrence, combined with Expected Value (EV) function, Monte Carlo simulation, Program Evaluation Review Technique PERT method making predictions cost time overruns. A case study hazardous event operations mine demonstrates as flexible low-cost tool executives. useful stage pre-disaster management mineral industry, considering sustainability views. The research work also investigates critical technical economic aspects.
