Abstract
PT. Tansri Madjid Energi merupakan perusahaan penambangan batubara
yang berlokasi di Gunung Megang, Kabupaten Muara Enim, Provinsi Sumatera
Selatan. Perusahaan telah selesai melakukan eksplorasi pada blok “Z” maka
perusahaan memerlukan perhitungan sumberdaya batubara untuk melakukan
eksplorasi lanjut dan perencanaan penambangan batubara. Data yang didapat
adalah data eksplorasi yang berupa data bor yang kemudian dianalisis agar
diketahui gambaran endapan batubara dan jumlah tonase sumberdaya batubara.
Metode penelitian yang digunakan adalah metode Cross Section dengan
Rule Of Gradual Change membandingkan perhitungan luasnya yang
menggunakan perhitungan luas aturan Simpson 1/3 dengan aturan Simpson 3/8.
Tujuan dari penelitian ini yaitu membandingkan besar sumberdaya batubara
menggunakan perhitungan luas aturan Simpson 1/3 dengan Simpson 3/8.
Di lokasi penelitian dijumpai 2 seam batubara yang memiliki ketebalan
0,99 –11,72 m. Seam ini merupakan bagian dari formasi muara enim. Seam ini
mempunyai jurus (strike) N 285° E dan kemiringan (dip) 4°-14°. Seam ini
membentuk perlapisan dengan arah jurus Barat Laut dengan arah kemiringan
perlapisan arah Timur Laut.
Tonase sumberdaya batubara dengan metode cross section menggunakan
perhitungan luas aturan Simpson 1/3 adalah 39.038.131,6 Ton dan untuk aturan
Simpson 3/8 sebesar 39.267.068 Ton. Perbedaan hasil perhitungan sumberdaya
menggunakan perhitungan luas aturan Simpson 1/3 dan aturan Simpson 3/8
adalah sebesar 228.936,4 Ton.
Dilihat dari klasifikasi Standarisasi Nasional Indonesia (SNI) SNI 5015-
2011, batubara di daerah penelitian termasuk kondisi geologi moderat jarak titik
informasi ≤ 250 m dengan kategori Sumberdaya Batubara Terukur (Measured
Coal Resourced).
Perlu dilakukan perhitungan cadangan batubara di daerah penelitian dan
dilakukan kajian teknis penambangan, ekonomi, pemasaran, hukum, lingkungan,
sosial dan peraturan pemerintah untuk penyusunan dokumen studi kelayakan
tambang. Untuk mendapatkan hasil perhitungan cadangan yang lebih akurat, maka
dibutuhkan tahap eksplorasi yang lebih rinci lagi dengan cara mempersempit jarak
antara lubang bor yaitu sekitar ≤ 100 m
PT. Madjid Tansri Energy is a coal mining company located in Gunung
Megang, District of Muara Enim, South Sumatra Province. The Company has
completed exploration in block "Z" and then the company requires the estimation
of coal resources and reserves planning for coal mining. The data obtained are in
the form of data exploration drill data were then analyzed to be known description
of coal deposits and coal tonnage.
The method used is of Cross Section Method with Rule Of Gradual
Change calculations comparing the extent that using calculation of area rule
Simpson 1/3 with Simpson rule 3/8. The purpose of this study is to compare large
coal resources using area calculation rule Simpson 1/3 with Simpson 3/8.
In study 2 found that coal seam has a thickness of 0.99 -11.72 m. Seam is
part of the Formation Muara Enim. Seam has a strike N 285 ° E and dip 4 ° -14 °.
Seam is formed by layering moves toward the Northwest with a slope towards the
Northeast bedding.
Coal resource tonnage by the method of cross section calculation of area
rules using Simpson's 1/3 is 39.038.131,6 tons and to rule Simpson 3/8 amounted
to 39.267.068 tons. A difference a result of calculation resources used calculation
of area rules Simpson 1/3 and rules Simpson 3/8 is worth 228.936,4 tons.
Viewed from the National Standardization of Indonesia ( SNI ) SNI 5015-
2011, the coal in the research area including the condition of geology moderate a
distance of a point of information ≤ 250 yards with the category of measured coal
resourced.
Needs to be done calculations coal deposit in the area of research and
technical research by mining, economy, marketing- law, the environment, social
and government regulation document to the preparation of a feasibility study on a
mine. To get the result of reckoning reserves that more accurate, it takes the stage
exploration more detailed again by means of a narrowing the distance between a
drill hole which is about ≤ 100 m.
