ASSESSMENT AND MANAGEMENT OF SAFETY RISKS THROUGH HIERARCHICAL ANALYSIS IN FUZZY SETS TYPE 1 AND TYPE 2: A CASE STUDY (FARYAB CHROMITE UNDERGROUND MINES)

There is a high rate of casualty among miners in the world every year. One way to reduce accidents and increase safety mines use risk management process identify respond major hazards mines. The present study an attempt investigate assessment risks Faryab chromite underground In this paper, method AHP type-1 type-2 fuzzy sets used for assessment. Upon studying two (Makran Nemat), 45 were divided into 9 groups, which 7 main eventually identified. showed that most important Nemat mine are required airflow, lack proper scaling post-blast scaling. Similarly, Makran scaling, absence ventilation dust, hazards. Finally, after detecting causes accidents, based on records at safety, health, environmental unit, technical personnel’s descriptions, similar projects, responses prepared each group
