Abstract
RINGKASAN Konsesi Perjanjian Karya Pengusahaan Pertambangan Batubara (PKP2B) PT. Teguh Sinarabadi memiliki luas sebesar 2.404 Ha. Berdasarkan hasil survei lapangan dan kegiatan pemboran eksplorasi dijumpai sebanyak 15 seam (lapisan) batubara di blok Lysat 2 dengan ketebalan antara 0,2-4 m. Arah umum penyebaran batubara (strike) relatif Timur Laut-Barat Daya, arah kemiringan (dip direction) ke Tenggara, dan sudut penunjaman (dip) berkisar 35-45º. Berdasarkan penaksiran cadangan yang dilakukan pada blok Lysat 2 diperoleh total cadangan sebesar 9 juta ton. Batas SR (stripping ratio) penambangan rata-rata 12:1. Permasalahan pada penelitian ini ialah PT. Teguh Sinarabadi perlu melakukan perancangan penambangan yang meliputi perancangan jadwal produksi batubara. Metode penyelesaian masalah dilakukan dengan pengolahan data sekunder yang meliputi data eksplorasi dan pemboran, sehingga menghasilkan pemodelan geologi, penaksiran cadangan, perancangan pit penambangan, dan penjadwalan produksi batubara. Hasil yang diperoleh untuk penjadwalan produksi batubara pada daerah telitian, yang dilakukan selama 4 tahun yakni: a. Tahun I produksi batubara sebesar 2.032.729,04 ton, pengupasan overburden sebesar 25.162.224,39 BCM dengan stripping ratio (SR) 12,4:1. b. Tahun II produksi batubara sebesar 2.185.036,07 ton, pengupasan overburden sebesar 26.847.353,69 BCM dengan stripping ratio (SR) 12,3:1. c. Tahun III produksi batubara sebesar 2.059.088,48 ton, pengupasan overburden sebesar 25.193.003,51 BCM dengan stripping ratio (SR) 12,2:1. d. Tahun IV produksi batubara sebesar 2.117.718,28 ton, pengupasan overburden sebesar 23.926.907,16 BCM dengan stripping ratio (SR) 11,3:1. Jumlah total produksi selama empat tahun adalah 8,3 juta ton, dengan nilai Stripping ratio (SR) rata-rata dari seluruh penambangan adalah 12:1. Penimbunan overburden dilakukan pada 2 tumpukan waste dump di sebelah Tenggara pit penambangan dan pada inpit dump di sisi Timur Laut pit penambangan. Alat gusur yang digunakan bulldozer Komatsu D375A-5, alat gali dan muat yang akan digunakan untuk mengupas material overburden adalah backhoe excavator Hitachi 2500-5, alat gali dan muat yang akan digunakan untuk memuat batubara adalah backhoe excavator Komatsu PC300SE-7 dan alat angkut yang akan dipakai untuk mengangkut overburden dump truck Komatsu HD785-7 dan alat angkut yang akan dipakai untuk mengangkut batubara adalah dump truck Hino ZY1EWPD. ABSTRACT Stated from the Agreement of Teguh Sinarabadi’s Coal Mining Production Operation, the area of this firm is 2,404 hectares. Based on field surveys and drilling exploration, there are 15 seams with a thickness between 0.2 to 4 meters (m) in Lysat 2 blocks. General direction of coal layer (strike) relative North East to South West, dip direction to the South East, and the angle of dip ranges from 35-45 º. According to the reserve assessment that is conducted on the Lysat 2 blocks, it is acquired 9 million tons of coals. The maximum Stripping Ratio is 12:1. The research problem is Teguh Sinarabadi corporation needs to develop a new mine design. This design should include production schedules. The problem solving method should be done by analysing secondary data including exploration data and drilling result. It will give a result in geological modeling, reserve estimation, mining pit design and coal scheduling production. The results that is obtained for scheduling of coal production and overburden in Lysat 2 block, which will be conducted in 4 years are: a. In the first year, the coal production are 2,032,729.04 tons, overburden removal amount is 25,162,224.39 BCM with 12,4:1 stripping ratio. b. In the second year, the coal production are 2,185,036.07 tons, overburden removal amount is 26,847,353.69 BCM with 12,3:1 stripping ratio. c. In the third year, the coal production are 2,059,088.48 tons, overburden removal amount is 25,193,003.51 BCM with 12,3:1 stripping ratio. d. In the fourth year, the coal production are 2,117,718.28 tons, overburden removal amount is 23,926,907.16 BCM with 11,3:1 stripping ratio. The total amount of production for four years was 8.3 million tons, with stripping ratio average of all mining is 12:1. Overburden deposited in two stacks waste dump that located in the South East of pit. While the inpit dump is inside the North East mining pit. There are several mining equipments used in Lysat 2 block. First, for overburden stripping used Komatsu bulldozer D375A-5. Second, excavator that will be used to dig and load overburden material is 2500-5 Hitachi. Third, the excavator that will be used to dig and load coal is PC300SE-7 Komatsu. Fourth, transport equipment that will be used to haul the overburden dump trucks Komatsu HD785-7 and the haulage unit that will be used to transport coal is ZY1EWPD Hino dump truck.
