Abstract

Mining is among the most dangerous activities around the world, which is always associated with various incidents, injuries, loss of life, and property damage. There are many safety, health and environmental hazards in the workplace that neglecting them and not planning to control them can have irreparable consequences.‌ Therefore, risk assessment is important in these mines. The purpose of this study is to provide a model for the analysis of the hazards associated with wire cutting machine using fuzzy fault tree analysis in stone dimensional mines. In the present study, after conducting studies and collecting information about the causes of the risks associated with the wire cutting machine, judging through the questionnaire by the relevant experts and identifying the risks associated with the cutting wire, then analyzing has occurred and rooting the causes of the hazards using fault tree analysis method. Considering the tree model that was created with this method, used fuzzy theory to weigh the root causes identified as Basic Events in order to eventually obtain the probable occurrence of any Basic events. The results show that the highest probability of occurrence among Intermediate Events is respectively for the dangers of maintenance, the dangers of geological issues and the dangers of improper design and the highest probability of occurrence among Basic Events is respectively for the dangers of move and whipping caused by the rupture of wire, the dangers of diversion of wire cutters and the dangers of existence Lakarty (mud) inside the stone blocks. Finally, due to the control methods, an appropriate response to these risks is presented.
