Int J Ind Operatons Res 2019, 2:003 Risk Management for Truck-LHD Machine Operatons in Underground Mines Using Failure Modes and Efects Analysis Muharrem Kemal Özfırat 1* , Mustafa E Yetkin 1 and Pınar Mızrak Özfırat 2 1 Engineering Faculty, Department of Mining Engineering, Dokuz Eylul University, Buca-İzmir, Turkey 2 Engineering Faculty, Department of Industrial Engineering, Celal Bayar University, Yunusemre-Manisa, Turkey Abstract In underground metal mines, cross-sectons 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 waitng. Ore is loaded to trucks at transfer points and moved out of the mine. In this study, risks in transfer operatons of ore from LHD machines to trucks are considered using Failure Modes and Efects Analysis. Risks which turn out to have risk priority number greater than 100 are handled urgently and risks priorites are decreased with the necessary precautons. Keywords Underground metal mine, LHD, Underground truck, FMEA There also exists studies which analyzes risks us- ing FMEA in mining industry. Ozfrat [13] proposed a fuzzy FMEA methodology and employed it for an underground coal mine. Eyuboglu and Ozfrat [14] identfed the potental hazards in underground metal mining and computed risk priority numbers (RPN) by FMEA. Ventlaton in the mine is found to be one of the highest risks in underground metal mines. Malli, et al. [15] employed FMEA for truck accidents in open pit mining. They identfed poten- tal risk and for high priority risks, they proposed necessary engineering precautons mostly based on early warning sensors and virtual reality solu- tons. Ozfrat, et al. [16] also used FMEA for risk evaluaton of haulage operatons in underground Introducton Failure Modes and Efects Analysis (FMEA) was frst developed and used in aviaton industry in 1960s [1]. FMEA is a method which evaluates potental hazards and, in this method, potental hazards are identfed and evaluated and correctve actons are suggested to prevent the occurrence of a hazard [2]. FMEA can be applied both in manufacturing and service industries. Failure mode is defned to be the potental failure state in the system, product, process etc. [3]. Today, FMEA is commonly used in many areas such as aviaton, automotve, electronics, chemistry, engineering and medical technologies [4-12].
