Abstract

Mine fleet management has a significant impact on increasing profitability and productivity. Also failure to meet production planning targets, increasing delays and waiting times requires monitoring to improve their performance. In this research, using Arena software base on discrete event simulation technique, modeling and analysis of current performance of loading and haulage operations performed for waste transportation in Mehdi Abad lead &zinc mine. Then appropriate improvement approaches suggested. For this purpose, first by analyzing production operations, trucks and loaders were identified as simulation entities and resources. Then, mine pit, repair shops and waste dump were defined as model subsystems. After analyzing of collected data of loading, haulage and navigating times of mine roads, the distribution functions of each operation estimated with the Input Analyzer tool. According to the simulation results, the loader productivity of mine is low, which will increase as the depth of the mine increases. Haulage road expansion. Then, the behavior of the system was simulated with two scenarios were defined including decreasing of overloaded loaders and adding trucks in 63 different modes. According to the results of the study, doubling the number of 30-ton trucks will maximize both the average service of loaders and trucks. On the other hand, it is possible to remove 2 loaders without significantly altering the performance of the remaining active loaders.
