Abstract
RINGKASAN
Penaksiran sumberdaya didapatkan melalui perhitungan dan analisis
terhadap data eksplorasi detil yakni berupa data pemboran. Penaksiran sumberdaya
dilakukan agar dapat mengetahui taksiran jumlah tonase sumberdaya batubara dan
selanjutnya akan dilakukan perhitungan stripping ratio pada lahan tersebut. Lokasi
pemetaan terletak di daerah konsesi PT. Raja Kutai Baru Makmur seluas ± 176 Ha,
terletak di desa Kutai Lama, Kecamatan Anggana, Kabupaten Kutai Kartanegara,
Provinsi Kalimantan Timur.
Tujuan dari penelitian ini adalah mengaplikasikan metode Cross Section
dalam menentukan dan mengestimasi jumlah sumberdaya batubara di daerah
penelitian
Metode yang digunakan dalam penelitian ini adalah dengan cara
pengamatan di lapangan menggunakan metode penaksiran cadangan yakni metode
Cross Section dengan membandingkan antara pedoman perubahan bertahap (rule of
gradual change) dengan pedoman titik terdekat (rule of nearest point).
Hasil penelitian yang diharapkan adalah dapat menentukan volume
sumberdaya pada overburden, seam A, interbarden dan seam B, menentukan tonase
batubara, dan stripping ratio (SR).
Sumberdaya terukur (Measured Resource) yang dihitung dengan
menggunakan metode Cross Section berdasarkan pedoman perubahan bertahap
(rule of gradual change) diperoleh seam A adalah sebesar 1.306.918,35 ton dan
seam B adalah sebesar 540.591 ton, jadi total tonnage Batubara adalah sebesar
1.847.509,35 ton. Volume overburden dan interburden yang didapatkan adalah
sebesar 9.596.094 BCM dengan SR 5,19:1.
Metode Cross Section berdasarkan pedoman titik terdekat (rule of nearest
point) diperoleh seam A adalah sebesar 1.367.026,90 ton dan seam B adalah sebesar
561.940,96 ton, jadi total tonnage batubara adalah sebesar 1.928.967,86 ton. serta
volume overburden dan interburden yang didapatkan adalah sebesar 9.896.220,45
BCM. dengan SR 5,13:1.
ABSTRACT
The estimation of resources obtained through the calculation and the
analysis towards the data of the details exploration that is the drilling data. The
estimation of resources was performed in order to find out the estimated amount of
tonnage of coal resources and then will continue with calculation of stripping ratio
at research area.. The location of mapping which is located in the area of the
concession of PT. Raja Kutai Baru Makmur is 176 Ha, which is located in the
village of Kutai Lama, Sub-district of Anggana, District of Kutai Kartanegara, East
Borneo province.
The aim of this research is to apply the Cross Section method to determine
and to estimate the amount of coal resources in the research area.
The method used in this research is observation in the research area using
the estimation of reserve method by comparing between the Cross Section of a
gradual change and Cross Section of nearest point.
Expected results of this research is to be able to determine volume of
overburden, seam A, interburden and seam B, determine coal tonnage, and stripping
the ratio (SR).
Measured Resource that calculate by using the Cross Section method of
being based on rule of gradual change obtained amount of seam A tonnage is
1.306.918,35 ton and amount of seam B tonnage is 540.591 ton, so the total tonnage
coal is 1.847.509,35 ton. The volume overburden and interburden that obtained is
9,596,094 BCM with SR 5,19:1.
The Cross Section method was based on rule of nearest point obtained
amount of seam A tonnage is 1.367.026,90 ton and amount of seam B tonnage is
561.940,96 ton, so the total tonnage coal is 1,928,967.86 ton. The volume
overburden and interburden that obtained is 9,896,220.45 BCM. with SR 5,13:1.
