Abstract
PT. Rimau Energy Mining has a mine area permitted about 1,000 Ha. There
are total 7 seam of coal with a thickness between 0,3-5.9 m with calorific value
between 3,500 kcal - 5900 kcal. Direction of the spread of coal (strike) relative
from north to south and subduction angle (dip) ranges from 8- 30º.
Based on the calculation of reserve that has been done at Northen Rimau
Block shown the total amount of coal reserve is about 19.779.223 tonnes with
total amount of overburden is 65.727.964 BCM. The coal production target sets
by the company is about 2.940.000 tonnes/ year with Stripping Ratio is 4:1.
The results which has been obtained for coal production and overburden
schedulling at research area which is conducted each year along six years are :
1. In the 1
st
year, the total of coal getting is 3.347.230 tonnes, overburden
stripping is about 10.994.640 BCM with Stripping Ratio (SR) 3.3 : 1.
2. In the 2
nd
year, the total of coal getting is about 3.020.990 tonnes, overburden
stripping is about 10.501.290 bcm with Stripping Ratio (SR) 3.5 : 1.
3. In the 3
rd
year, the total of coal getting is about 3.407.328 tonnes, overburden
stripping is about 1010.529.480 bcm with Stripping Ratio (SR) 3.1 : 1.
4. In the 4
th
year, the total of coal getting is about 3.210.623 tonnes, overburden
stripping is about 11.069.281 bcm with Stripping Ratio (SR) 3.5 : 1.
5. In the 5
th
year, the total of coal getting is about 3.401.237 tonnes, overburden
stripping is about 11.341.401 bcm with Stripping Ratio (SR) 3.4 : 1.
6. In the 6
th
year, the total of coal getting is about 3.391.825 ton, overburden
stripping is about 11.291.872 bcm with Stripping Ratio (SR) 3.3 : 1.
Dozing equipment which used is Bulldozer Komatsu D575A-3SD, equipment
needs between 3-5 units / year with reserves of 1 unit / year. For digging and
loading equipments that will be used to strip the overburden material is backhoe
Liebherr R9350, it takes 1-2 units / year with reserves of 1 unit / year, hauling
equipment used to transport overburden is Komatsu HD 785 dump truck takes 2-18 units / year with reserves of 1-4 units. Digging and loading equipments used
for coal getting is excavator backhoe Komatsu PC200 LC-8, it takes 5-6 units /
year with reserves of 2 units / year, Hauling Equipment that will be used to
transport coal is FM260JD Hino dump trucks, it takes 13- 19 units / year with
reserves of 3-5 units / year.
Landfill cover in 1
st
until 3
rd
year carried on dumping areas located in the
northern block Northern Rimau, and in pit dump in 4
th
year until 6
th
. The width
of road transport is 20 m for straight road and 27.5 m for turning point with super
elevation value of 4% of the width of the road.
