Safety risk analysis in Ardestan Dare Ashki and Esfahan Moteh gold mines

Due to the increasing number of accidents while working in the mines, studies related to maintaining the safety and health and improving safety management are expanding today. To reduce accidents and injuries, risk assessment should be performed continuously in the mines. For this purpose, two gold mines of Ardestan Dareh Ashki and Isfahan Moteh were examined. In the first stage of risk assessment, information on hazards in the mines was collected and in the second stage, the probability of occurrence and severity of its effect were evaluated. The two gold mines were then developed using methods similar to the ideal option and fuzzy logic to assess the risks The total hazards of the ore mining and concentrating operations in these mines were 136, which were classified into 8 groups. Finally, after completing the necessary calculations, several groups with different risks were obtained. The first group with the highest risk included unpredictable explosions, non-standard explosives, tailings dam failure, cyanide leakage, people falling into the tailings dam, electrocution while working with equipment, slipping or slipping, not wearing safety clothing, unauthorized entry It was in the area of ​​extraction and explosion during firefighting. Based on the obtained results, it is possible to plan and take appropriate action to prevent the occurrence of undesirable results.
