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.
