dc.description.abstract | Road grade and mining activities are inseparable.
Considering that a mining site is located in a lower
elevation, the haul road is usually constructed
following the topographic contour. A road grade is likely to
affect the speed, travel time, and fuel consumption and is
directly proportional to the energy required by dump trucks
to overcome resistance. A higher road grade leads to more fuel
consumption, while a lower road grade is likely to consume
less. This study found that every 1% road grade increase results
in 0.482%-0.515% increased engine speed and 2.79% horsepower
under laden conditions. It was also found that every
1% road grade increase leads to 21.95% more fuel consumption
in CAT 773D dump truck, 23.64% in HD-465-7 dump truck,
and 13.29% more fuel consumption in Volvo A40E. Meanwhile,
under unladen conditions, every 1% increase in road grade
resulted in 7.64% more fuel consumption in CAT 773D,
20.60% in HD 465-7, and 23.75% in Volvo A40E. This study
recommends an 8% maximum road grade to save fuel for
hauling activities in the mining area. | en_US |
