Abstract. The research was conducted at PT Dizamatra Powerindo in the Merapi Sub-district, Lahat Regency, South Sumatra Province. The purpose of this study, to design a pit with economical SR and to make phases of pit design.Based on the calculation results of BESR2 (Break Even Stripping Ratio) obtained a value of 4.56:1 and the calculation of Economical SR obtained a potential economic limit of stripping ratio of 3.42:1.The final pit design has a total elevation depth of -55 meters with a pit opening area at the end of the coal mine in the research area of 229.83 Ha, obtained proven coal reserves of 51,780,460.51 tons of coal and Overburden volume of 168,253,972 BCM with SR 3.42 BCM/Ton. The company's production target is set at 2,000,000 tons of coal/year with a mine life of 25.89 years.Keywords: Reserve, Pit Design, Stripping Ratio, Phasing.Abstrak. Penelitian dilakukan di PT Dizamatra Powerindo yang berada di kecamatan Merapi, Kabupaten Lahat, Provinsi Sumatera Selatan. Tujuan dari penelitian ini, untuk membuat rancangan pit dengan SR ekonomis dan membuat pentahapan desain pit. Berdasarkan hasil perhitungan BESR2 (Break Even Stripping Rasio) diperoleh nilai 4,56:1 dan perhitungan SR Ekonomis diperoleh batas potensial ekonomis nisbah kupas yaitu 3,42:1.Rancangan akhir pit memiliki total kedalaman elevasi -55 meter dengan luas bukaan pit pada akhir tambang batubara daerah penelitian sebesar 229.83Ha, didapatkan cadangan batubara terbukti sebesar 51.780.460,51 ton batubara dan volume Overburden sebesar 168.253.972 BCM dengan SR 3,42 BCM/Ton. Target produksi perusahaan ditetapkan sebesar 2.000.000 ton batubara/tahun dengan umur tambang 25,89 tahun.Kata Kunci : Cadangan, Desain Pit, Stripping Rasio, Pentahapan Tambang. |
