Risk Assessment in Quarries using Failure Modes and Effects Analysis Method (Case study: West-Azerbaijan Mines)

Iran is one of the countries with the largest number of quarry mines in the world.
Diamond cutting wire is usually used in quarries to cut dimension stone cubes, which
is accompanied by hazardous events. Therefore, detecting and investigating the
possible quarry risks is crucial to have a safe and sustainable mining operation. In mine
exploitation, maintaining the safety of vehicles and increasing the knowledge of
personnel regarding safety issues can considerably mitigate the number or radius of
effect of hazards. Hence, the incidents and risks in the West-Azerbaijan quarries in
Iran are investigated in this work. To do so, a list of the hazards and their descriptions
are first prepared. Then the hazard risk rating is conducted using the Failure Modes
and Effects Analysis (FMEA) method. The number of priorities is calculated for each
incident based on probability, intensity, and risk detection probability. Finally, the
main causes of risks in the studies quarries are identified. The results obtained show
that the most likely dangers in dimensional stone mines in West Azerbaijan are
diamond cutting wire breaking, rock-fall, and car accidents, with the priority numbers
of 216, 180, and 135, respectively. These hazards can be mitigated by applying some
preservative activities such as timely cutting wire replacement, utilizing an intelligent
system for cutting tool control, necessary personal training, and considering some
preservative points.
