Abstract

In 2025, PT. Duta Bara Utama targets coal production of 2.250.000 tons of coal with SR that must less than 3,5. The actual production in January 2025 was 112.480,03 tons of coal and 230.486,10 BCM of overburden. . The out pit dump disposal areas, namely the northern and southern disposals in 2025, cannot accommodate the planned overburden volume, so dumping will be done in the in pit dump. Planning for loading and hauling equipment requirements is using Microsoft Excel 2021, mining scheduling is created with the help of Spry software, while pit and disposal designs are created with Minescape 5.7 software. In the first quarter, the production plan is 374.881,49 tons of coal and 1.219.000,96 BCM of overburden with an SR of 3,25. In Quarter II, the production plan is 544.345,39 tons of coal and 2.015.154,65 BCM of overburden with an SR of 3,70. In Quarter III, the production plan is 641.818,95 tons of coal and 2.375.999,62 BCM of overburden with an SR of 3,70. In Quarter IV, the production plan is 707.918,65 tons of coal and 1.978.860,85 BCM of overburden with an SR of 2,80. The total production plan for the year 2025 is 2.263.888,79 tons of coal and 7.589.016,09 BCM of overburden with an SR of 3,34, which achieve the specified production target. Then, mining scheduling will be performed using the trial and error method on the Spry software until a scenario is found that achieve the production targets and the exposed coal balance. The pit design and disposal plans for quarters I, II, III, and IV are designed based on the planned coal tonnage and volume of overburden.
