Abstract
Overburden volume at pit 5 PT. Tambang Bukit Tambi site Padang Kelapo is 1,496,925.78 BCM which is located in an area of 10.15 Ha with a disposal distance of 100 – 300 meters. The production target based on the available equipment is 1,483 BCM/hour. The dig-and-load equipment used is the Excavator Komatsu PC-400 LC with equipment productivity of 456.401 BCM/hour with 4 units of equipment, so the productivity of the dig-and-load is 1,825.604 BCM/hour. Then the productivity of the Articulated Dump Truck (ADT) Volvo A40G is 204.248 LCM/hour with 10 units of equipment, so the productivity of the transportation equipment is 2,042.48 LCM/hour. The overburden excavation activity is divided into 4 sequences starting from an elevation of 95–75 in sequence 1 with an overburden production target of 370,008.5 BCM, followed by an elevation of 75–70 in sequence 2 with an overburden production target of 332,933.5 BCM, then from elevation 70–65 in sequence 3 with an overburden production target of 391,512 BCM and the last from an elevation of 65–55 in sequence 4 with an overburden production target of 402,472 BCM. For the overburden excavation activity, 4 units of dig-and-load equipment and 10 units of transportation will be used so that the time needed to carry out mining activities from start to finish is around 83 working days.
