Abstract: B15, B20 and B30 have been used to fuel coal mining operations dump truck. With the same type of dump truck and mileage, the calculation results show that the specific fuel consumption of B15 is 1.42 liters/ton of coal, the specific energy consumption of B20 increases to 1.43 liters/ton of coal and the specific energy consumption of B30 decreases to 1.42 liter/ton of coal. This decrease occurred due to the implementation of an energy management program by implementing smart driving, which is turning off the dump truck engine when it is not running.
