Abstract
In underground metal mines, cross-sections of galleries can be made larger compared to coal mines. Therefore, underground mining trucks Load-Haul-Dump (LHD) machines can easily be used for haulage of ore in underground metal mines. Ore produced is taken by LHD machines and moved to transfer points where trucks are waiting. Ore is loaded to trucks at transfer points and moved out of the mine.
Highlights
Failure Modes and Effects Analysis (FMEA) was first developed and used in aviation industry in 1960s [1]
FMEA is a method which evaluates potential hazards and, in this method, potential hazards are identified and evaluated and corrective actions are suggested to prevent the occurrence of a hazard [2]
Eyuboglu and Ozfirat [14] identified the potential hazards in underground metal mining and computed risk priority numbers (RPN) by FMEA
Summary
Failure Modes and Effects Analysis (FMEA) was first developed and used in aviation industry in 1960s [1]. Eyuboglu and Ozfirat [14] identified the potential hazards in underground metal mining and computed risk priority numbers (RPN) by FMEA. Employer should perform risk evaluation and list sources of hazards, identify risks, take precautions for employers’ safety By this way, work accidents can be reduced, loss and damages can be decreased, quality and productivity can be increased. Ore is transferred from LHD machines to trucks at transfer points in mine (Figure 3) Since these operations are heavy duty and take place in an underground area, there may be important risks in the work environment. In this, study, risk evaluation of truck-LHD machine ore transfer operations are considered using FMEA. Since F9 and F11 risk scores cannot be decreased further, both the employer and employees should be more careful with these risks
