Abstract

To support underground mining activities, good and effective ground support is needed. The coal production target at the mining site in May 2019 for the production target set in one Komatsu PC 2000 fleet is 1,115,836 tons / hour. From the results of the calculations done, the actual productivity for the PC 2000 is 776.086 tons / hour. The cause of the actual productivity of the equipment used has not reached the production target is due to work constraints which cause the effective working time of the tools to be low and the MA value of the tools that is not good. To increase the productivity of each piece of equipment, it can be done by reducing the time constraints that can be avoided such as delays in work, leaving early, resting too quickly and starting late after rest in order to increase the effective working time of the equipment. The minimum fuel consumption of B20 biodiesel is lower than diesel fuel, which is 84 kg / hour compared to 92 kg / hour of diesel fuel. The average torque of diesel fuel is 423.4 kg.m and the average torque of B-20 biodiesel fuel is 400.3 kg.m.
