Risk Management for Truck-LHD Machine Operations in Underground Mines Using Failure Modes and Effects Analysis

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. In this study, risks in transfer operations of ore from LHD machines to trucks are considered using Failure Modes and Effects Analysis. Risks which turn out to have risk priority number greater than 100 are handled urgently and risks priorities are decreased with the necessary precautions.
