Abstract

PT Banjarsari Pribumi is located in Lahat Regency, South Sumatera Province. Which is a subsidiary of PT Titan Infra Energy and has 3 contractors namely PT Manggala Usaha Manunggal, PT Anugerah Bumi Lestari and PT Anugerah Covindo Indonesia. PT Banjarsari Pribumi started mining coal since 2015. Currently, PT Banjarsari Pribumi mines two pits namely pit middle and pit south. In 2023 PT Banjarsari Banjarsari plans to produce 1 million tons of coal form pit middle, so a mining plan is needed that can support the production target. This study aims to mining plan which includes pit and disposal design, mining sequences with handling of east ABC OPD materials and analyzing the needs for loading and transporting equipment. The design of mining pit, disposal and monthly sequences is made using software minescape 5.7 by selecting mining blocks by trial and error with a stripping ratio value of 6,2 and monthly production target set by PT Banjarsari Pribumi. The result of the pit design obtained an estimated reserve of 1.014.675 tons of coal and 5.821.600 BCM of overburden with 5,74 stripping ratio. The pit design is made by taking into account the recovery of east ABC OPD material at pit middle and the mining sequences design is planned monthly which is capable to supporting the coal production target of 1 million tonnes. The direction of mining starts from the east side wall, continuing the previous mining to the west side wall with an opening area of 39,18 Ha. The sequence disposal design is planned to be an inpit dump in the IPD ABC area with an opening area of 44,30 Ha which can accommodate overburden of 7,99 million BCM. The combination of digging and transporting overburden equipment from January to September is used 5 fleets with a combination of 1 unit excavator with 6 units of dump trucks, in October is used 4 fleets with a combination of 1 unit excavator with 6 units of dump trucks, in November 4 fleets and in December 2 fleets with a combination of 1 unit excavator with 7 units of dump trucks. Meanwhile, for coal getting activities, 1 fleet is used with a combination of 1 unit excavator with 6 units of dump trucks every month. Keywords : Mining Plan, Sequence, East ABC OPD, Minescape 5.7, Stripping Ratio
