Assessment And Management Of Safety Risk Using Fuzzy Analytical Hierarchy Process Method In Faryab Open-Pit Chromite Mines

In the world, high levels of severe damage are reported annually among persons in mines. One of the effective ways to provide the necessary safety in mines is to use a comprehensive management and planning system to determine the main hazards in the mines and respond to them. Therefore, in this paper, the hierarchy analysis method is used to evaluate and manage the safety risk in Chromit Faryab open-pit mines. According to a survey in four mines of Chromite Faryab, at first step, 78 risks identified. After a survey of 63 miner who work in the mines, 27 risks identified in 6 groups (geology, drilling and blasting, transportation, machinery and equipment, laws and regulations, and individual errors) as important risks. By using Fuzzy Analytical Hierarchy Process method 11 risks is identified as the main risks in the mines. The results show that the drilling and blasting group and individual errors are respectively (0.178 and 0.173), the most important of the risks in the Chromite Faryab mines. Finally, for each group of hazards, the appropriate risk is responded based on the incident documentations, the description of the experts and incidents in similar projects.
