Abstract
PT. Sarana Makmur Bersaudara experienced an increase in production targets of 520,000 tons/year, 1,100,000 tons/year, and 1,800,000 tons/year due to the increased market demand. As of production target uplift, there's an issue about coal resource model classification, East Block mining direction, and design simulations recommendation. This research includes literature study, field observation, and mechanical equipment observation. The coal seam model, final mining design, and mining progress using Minescape 5.7. The mechanical requirements calculation using Microsoft Excel 2010. East Block resource classified as indicated coal resource. The mining direction is carried out from south to north because the coal seam dimensions in the southern area are closer to the earth's surface and the seam dip direction is to the north. Based on mine design simulations results, were obtained design I with a coal production target of 524,000 tons/year, OB of 880,000 BCM/year, and SR of 1.6:1; design II with a coal production target of 848,000 tons/year, OB of 2,396,000 BCM/year and SR of 2.1:1; and Design III with a coal production target of 1,864,000 tons/year, OB of 4,893,000 BCM/year, and SR of 2,6:1. Based on the HBA in July 2021, recommended applying design III with total revenue of 217,108,000 USD. Keywords: Design, Losses, Match Factor. Resources ABSTRAK PT. Sarana Makmur Bersaudara mengalami peningkatan target produksi sebesar 520.000 ton/tahun, 1.100.000 ton/tahun, dan 1.800.000 ton/tahun yang diakibatkan oleh meningkatnya permintaan pasar pasar. Akibat meningkatnya target produksi memunculkan permasalahan yaitu diperlukan klasifikasi model sumberdaya batubara, menentukan arah penambangan pada Blok Timur, dan merekomendasikan simulasi rancangan. Metode penelitian ini meliputi studi literatur, observasi lapangan dan pengamatan alat mekanis. Model lapisan batubara, rancangan akhir penambangan, dan kemajuan penambangan dibuat menggunakan software Minescape 5.7 dan perhitungan jumlah kebutuhan alat menggunakan Microsoft Excel 2010. Penelitian pada Blok Timur menghasilkan model sumberdaya batubara dengan klasifikasi sumberdaya tertunjuk. Arah penambangan dilakukan dari selatan ke utara dikarenakan dimensi lapisan batubara di daerah selatan lebih dekat dengan permukaan bumi dan arah kemiringan lapisan ke arah utara. Berdasarkan hasil perancangan desain tambang, didapat simulasi: (i) Rancangan I dengan target produksi batubara 524.000 ton/tahun, OB sebesar 880.000 bcm/tahun, dan SR 1,6:1; (ii) Rancangan II dengan target produksi batubara 848.000 ton/tahun, OB sebesar 2.396.000 bcm/tahun dan SR 2,1:1; dan (iii) Rancangan III dengan target produksi batubara 1.864.000 ton/tahun, OB sebesar 4.893.000 bcm/tahun, dan SR 2,6:1. Berdasarkan HBA pada Juli 2021 sebesar 115,35 USD/ton, direkomendasikan rancangan III dengan total pendapatan sebesar 217.108.000 USD. Kata kunci: Faktor Keserasian, Losses, Perancangan, Sumberdaya.
