Abstract

Based on the observation of actual conditions on the HD 465-7 Dump Truck Fuel Consumption in Coal Mining, it turns out that the level of fuel consumption for transportation equipment is still quite high. To find out what is the cause of the high fuel consumption, a study was conducted on the ratio of fuel used in mining activities. The fuel consumption standard set for loading and unloading equipment is 0.5 Liter/BCM. From the calculation of theoretical fuel consumption, if the haul line is repaired by lowering the slope of the road, the fuel consumption can be reduced to close to the target fuel ratio. The amount of fuel used is more influenced by the condition of the haul road with a slope that is too large. The more intersections the conveyance passes through, the more fuel consumption the conveyance will affect due to a reduction in speed for transportation safety This problem can be avoided by making good mine planning, ideal road slopes, maintenance of haul roads so that in the end it is hoped that fuel consumption can be optimized. The specific fuel consumption of the conveyance unit is generally lower than that of the loader. This makes it the most efficient means of transport in the overburden hauling work. For this reason, it is necessary to study the variables that affect fuel consumption in coal mining using multivariable analysis.
