Design of Open Pit Mine for Ajabanoko Iron Ore Deposit Using Csmine

Abstract

The design and planning of an open pit mine is about the economics of the mine and are governed by geological and engineering characteristics. A mine design software (CSMine) was used to design the final pit limits, tons per block and number of benches for Ajabanoko iron ore deposit using pit restrictions. These restrictions are; surface constraints, geometric pit limits, outer economic bounds and floating cone bounds. The block model for the pit design was created using three sets of parameters which includes; the key block coordinates, the block size and the number of blocks in the X, Y, and Z directions. The final pit limit obtained for the deposit is 113.25m.
