Abstract

Fluctuations in coal prices pose a challenge for companies in optimizing the economic value of mining operations. In response, PT Bukit Asam Tbk has proposed two new boundaries for the design of a new pit in Pit 2 Banko. This study aims to design a new pit based on the proposed boundaries, plan the forecast of excavation and hauling equipment to determine the annual production until the end of mine life, and evaluate the net profit margin of the two new pit designs. The incremental pit expansion method was applied in the optimization of Pit 2 Banko, as its trial and error concept is effective in addressing both of these challenges. Annual production figures were derived from the productivity calculations of excavation and hauling equipment, which then allowed for the calculation of the net profit margin based on cash flow analysis. The results show that boundary A involves the removal of 96,371,408 bcm of overburden and yields 27,802,527 tons of coal, while Boundary B involves the removal of 144,814,008 bcm of overburden and yields 33,755,624 tons of coal. Operations are conducted using 10 overburden fleets and 7 coal fleets, with an average annual production of 32.128.359 bcm of overburden and 9.263.028 tons of coal, while for boundary B, it is 36.191.058 bcm of overburden and 8.436.186 tons of coal. The net profit margin is calculated at 11,30% for boundary A and 8,11% for boundary B. Based on these results, the pit design for Boundary A is suitable for advancement to the feasibility study stage, while the design for Boundary B may proceed to feasibility studies with more stringent evaluation.
