A Preliminary Study of Tramming Speeds in Multiple Tele-Operated Load-Haul-Dump Scenarios Using QUEST

Tele-operated Load Haul Dump (LHDs) machines are becoming a common tramming solution throughout many mines. To reach maximum productivity from multiple teleoperated LHDs, the system must achieve a proper balance of LHD speed in the haulage network and haulage layout geometry. A simulation model was used to evaluate the haulage system throughput with the LHDs tramming in second gear while under automatic guidance. The study indicated that allowing LHDs to operate in second gear for the specified haulage layout configuration may not provide an increase in the system capacity. The paper concludes that further investigation of key tramming system variables should be carried out to optimize LHD speed.
