Abstract

Surface mine is a mining system where all the mining activities are carried out on the planet surface or on open air environment. In the open mining system there are several methods, one of which is the open pit/cut. PT. Ifishdeco is one of the mining companies engaged in nickel ore mining and applies open mining system with open pit/cut method. PT. Ifishdeco Block X pit design is carried out with the help of Surpac 6.5.1 software. The design process starts with estimating reserves using the Inverse Distance Weighting (IDW) method then using the company recommendation to design levels geometry with bench dimension of 5 m high, 6 m width, 45o slope, overall slope of ≤ 25 0, catch bench width of 1 m and mine road width 8 m with 8% slopes. Furthermore, proceed with designing a pushback or progress of the mine based on the elevation with 5 months mining operation plan.
