ULTIMATE PIT LIMIT DESIGN USING HEURISTIC ALGORITHMS, CASE STUDY: SANGAN IRON DEPOSIT – IRAN
Abstract
The optimum pit limit design can be defined as determining the ultimate or final mining limits of ore deposit with maximum value or profit which is obtained from its extraction. Heuristic optimization techniques have been one set of the most widely used methods for ultimate pit limit analysis because of their rapid execution speed and easy conceptualization. This paper considers a heuristic technique, known as 3D moving cone to find the optimum pit limit of Sangan iron ore deposit in Iran. To evaluate the results aforementioned algorithm has compared with solution of 2D Dynamic programming of Learchs-Grossman which always leads to optimum solution in 2D Sections.
