Analysis Influence Of Grade And Distance Hauling Road On Fuel Consumption And Fuel Ratio In Andesite Rock Mining Activities At PT Gunung Sampurna Makmur Rengasjajar Village, Cigudeg Subdistrict, Bogor District West Java Province

Abstract

One component of mining production costs are the costs of fuel
consumption, so it is a concern because it contributes towards the operating cost in
mining activities. Some things that affect the fuel consumption on mechanical
devices, including the condition of the equipment, the actual conditions in mine
location, and operators treatment of the equipment. Therefore, it needs an
evaluation and analysis of the factors that influence need for the fuel consumption.
Andesite mining activities in the PT Gunung Sampurna Makmur done by
quarry mining methods. Loading equipment is used excavator KOBELCO SK 330
and hauling used Dump Truck MAN CLA 26.280. Loading production is 69,66
BCM/hour and hauling production is 22,80 BCM/hour. As for the actual production
transported from the loading point to the hopper in one day as much as 1830,24
BCM/Day. The average fuel consumption of loading equipment is 26,56 liters/hour,
while the average fuel consumption of hauling equipment for distance 1.200 m as
much as 8,36 Liters/Hour and for distance 1.400 m is 9,53 Liter/Hour.
By analyzing the slop road and distance of hauling road, it can be seen
diesel fuel needs for Dump Truck MAN CLA 26.280 on transport distance of 1,2 Km
with grade 7,25% is 0,13 Liters/Km/%, while at a distance transport 1,4 Km with
grade 6,42% is 0,16 Liters/Km/%. Fuel ratio actual value in the field for transport
distance of 1,2 Km is 0,65 Liters/BCM, while transport distance of 1,4 Km is 0,79
Liter/BCM.
