Abstract
ABSTRACT
The calculation of coal reserves is essential to determine the existence of
coal deposits. The calculation of coal reserves should be done optimally so that the
error rate is low and the calculation can be accountable.
This research has been done in PT Rimau Energy Mining in Janang, Paku
and Awang sub-districts, Barito Timur Regency, Central Kalimantan. The modelling
and calculation of coal reserves was done using Block model in Minescape software.
The modelling and calculation of coal reserves has been done in 7 seams
which consist of seam R01A, R01B, R02, R03A, R03B, R03C, R04D. The seams
were chosen based on its quality and thickness which were qualified for mining.
This research shows that coal resources in Barito Timur are about
15.327.169 tons for measured, 9.537.671 ton for indicated,and 10.962.198 ton for
inferred while coal reserves which are measured coal resources are about
11.218.134,46 tons: seam R01A 676.745,29 tons, seam R01B 966.757,48 tons, seam
R02 1.520.334,27 tons, seam R03A 1.918.239,57 tons, seam R03B 2.718.091,74
tons, seam R03C 3.274.002,03 tons, seam R03D 143.964,08 tons, and the amount of
overburden volume is 60.638.661,7 m

. The stripping ratio which was obtained is
1:5,505.
