TROLLEY TRUCK SIMULATION ON KACHAR MINE HAUL ROAD

https://doi.org/10.48498/minmag.2023.215.3.007

Transportation costs in open pit mining may take 50 to 70% of overall open pit mining cost. Diesel fuel consumption takes more than 25% of owning and operating costs of large mining haul trucks and represents about 50% of carbon emissions at open pit sites. Modern software uses built-in characteristics of machine as rimpull and breaking performance, fuel, and electricity consumption rates. Computer simulation of CAT 794AC with trolley assist on conditions of Kachar mine 3068-meter haul road with 1100-meter trolley line section demonstrated 22% fuel consumption reduction and 10,9% higher production compare with conventional CAT 794AC. Study shown possible future efficiencies and practical recommendations for trolley assist application. During the study the real haul road condition’s data taken from mine site and used for simulation of future operational performance indicators.
