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.
