MINING PUSHBACK DESIGN LATERITE NICKEL AT PIT 3 PT. ADHIKARA CIPTA MULIA DISTRICT OF LASOLO ISLAND, KONAWE UTARA REGENCY, SOUTHEAST SULAWESI PROVINCE
Keywords:
Nickel Laterite, Pushback, Stripping RatioAbstract
Adhikara Cipta Mulia inc operates in the nickel laterite mining sector located in Morombo Village, North Konawe, Southeast Sulawesi. The company holds a Mining Business License (Izin Usaha Pertambangan or IUP) covering an area of 455 hectares and employs an open-pit mining system. The research focus centers on Pit 3, spanning 13 hectares, requiring a pushback mining design based on monthly production targets. This study spanned 8 months and included monthly pushbacks with varying tonnages of ore, stripping ratios, and nickel grades. For instance, in the first month, the pushback yielded 183,216.47 tons of ore with a stripping ratio of 1:1.1 and a nickel grade of 1.82%. This pattern continued until the eighth month, marking an 8-month lifespan for Pit 3. The research outcomes provide insights into the efficiency and productivity of nickel laterite mining at the specified location.
