    Abstract

    This research do PT. Bintangdelapan Mineral ( BDM ) at Kabupaten Morowali, Province Sulawesi Tengah. Nickel mine using surface mining system with open pit method. BDM will enlarge the mine to blok 5 a pit 1 for request complete market will nickel, before doing mine must stripping overburden technic plan. Grade zone OB with COG ˂ 0,77 % Ni and grade zone Waste with COG < 0,99 % Ni, to judge as an overburden. The calculation result, total volume overburden at blok 5 a pit 1 = 1.193.283 BCM , while volume zone OB = 1.332.500 BCM and volume zone Waste = 157.500 BCM. Technic of stripping overburden at blokn 5 a pit 1 plant doing in this away class from high contour to low contour. Plan of geometry slope pit limit OB and Waste have bench height = 10 m with face angle = 63˚ and overall slope = 50˚. Plan of geometry slope disposal have bench height = 10 m with face angle = 40˚ and overall slope = 34˚. Mechanics tool to need is load tool Excavator Back Hoe Volvo EC 460 CL with capacity production 323,46 BCM/hours amount to 4 units and haul tool Articulated Dump Truck ( ADT ) Volvo A 40 E with capacity product ion 83,36 BCM/hours amount to 14 units.
