Abstract
PT Tanjung Alam Jaya plans to conduct mining activities in Pit 3 to extract coal from Seam A, Seam B, and Seam C. This area has dense vegetation and thick overburden material with a dip of 23-25 degree. The steep slope of the coal seam results in a high SR value as the mining deepens. The research method was conducted using quantitative method with primary data collection through field observation and secondary data from PT Bina Sarana Sukses and other sources. The data is processed and analyzed to determine the need for equipment and the planned mining design. The mining design for the first quarter of 2024 will start from the north area and widen to the south, following the strike direction of the coal seam. The design for the first quarter of 2024 Pit 3 is divided into three monthly sequence designs with a total overburden capacity of 2,264,048.21 BCM and 103,555.4 tons of coal, with an SR of 21.86 in accordance with the provisions of 115% of the production capacity of the equipment determined by the company. Equipment required for mining includes loaders and haulers, with a total of 3 loaders and 14 haulers. Overburden production capacity ranged from 621,160.89 BCM to 685,537.27 BCM for each three monthly sequence.
