PLANNING OF THE NEED FOR EXTINGUISHING AND TRANSPORTING EQUIPMENT IN THE LATERITE NICKEL ORE MINING SUB BLOCK 3B TAA BLOCK PT BUMI NIKEL NUSANTARA PUUWONUA VILLAGE, ANDOWIA DISTRICT, KONAWE UTARA REGENCY, SULAWESI TENGGARA PROVINCE

The potential for nickel ore in Southeast Sulawesi Province has encouraged PT. Bumi Nikel Nusantara to carry out activities in the mining sector with an area of Mining Business License (IUP) of around 386 Ha located in Puuwonua Village, Andowia District, North Konawe Regency, Southeast Sulawesi Province. PT. Bumi Nickel Nusantara plans to open a new pit in the TAA block, namely sub-block 3B due to production failures, so the number of digging and hauling equipment to be used for overburden stripping and ore getting in TAA sub-block 3B PT. Bumi Nikel Nusantara. Based on the research results, the number of mechanical devices used in each activity is different. In the overburden removal activity, 2 units of Komatsu PC300 excavators were used. The excavator loading and digging tools used for overburden removal are different from the tools used in ore getting activities, for ore getting activities use 2 Sumitomo 210 excavators. However, for overburden loading and ore loading, both use Komatsu PC300 excavators. For overburden loading activities, 2 Komatsu PC300 excavators were used, while for ore loading, only 1 Komatsu PC300 excavator was used. In selecting the means of conveying the two materials, both overburden and ore, both used the Hino FM 260 JD ID Dump Truck. For overburden transportation from pit to disposal using 4 units of dump trucks and for transporting ore from pit to ETO (Exportable Transit Ore) using 14 units of dump trucks.
