Abstract. In addition to providing benefits, marine mining activities can have a negative impact on the environment, causing various changes environment. One of efforts minimize resulting is Backfilling method, which direct closure ex-mining holes from ore reserves been taken in stages. this research, study reclamation planning and costs was carried out Sangau B.3 Block with an area 213.59 Ha. The technical includes studies manufacture installation FADs transplantation artificial coral reefs, maintenance monitoring sea water quality. will be by PT XYZ processing time 2,266.43 hours / 284 days 8 work per day. cost calculation indirect components, include FAD costs, reef transplant seawater quality while equipment mobility third party supervision costs. Based calculations, plan for 2023-2026 Rp. 12,354,487,782 5,588,398,553. So that total planned IDR 18,182,204,687.
 Abstrak. Selain memberikan manfaat, aktifitas penambangan laut dapat dampak negatif terhadap lingkungan laut, menimbulkan berbagai macam perubahan bagi laut. Salah satu upaya untuk meminimalisir yang ditimbukan, dilakukan metode merupakan penutupan langsung pada lubang bekas tambang sudah diambil cadangan bijihnya dengan cara bertahap.
