Abstract

PT Budi Gema Gempita is a mining company with coal commodities located in Lahat district, South Sumatra Province. 2021 Expansion of the mining area in section 2 as a step to achieve the company's annual production target, the specified production target is 1,100,000 tons of coal with a maximum stripping ratio (SR) of 4 bcm/ton. Placement of overburden disposal is planned by backfilling in the final pit plan area. The mining plan consists of a mining pit design and overburden removal for an annual period. The pit design is based on the area plan, production target, and mining geometry. Meanwhile, the design of the discharge design is made based on the selection of the disposal plan location, the appearance of the exhaust geometry, and the amount of overburden removed from the design pit design. The design is made through minescape 5.7 software. Research produces an annual plan on the available area plans. Total reserves are 1,258,737 tons of coal and 4,396,813 bcm of overburden, SR value of 3.49 bcm/ton, with an opening area of 40 Ha. The direction of progress is planned to extend to the south and west areas of the existing pit in a down-dip (lowwall to highwall) to the lowest elevation of RL +-24. Overburden stockpiling is planned by backfilling in the final pit area with a maximum distance of 1.6 km
