Mine Planning and Optimisation Techniques Applied in an Iron Ore …
A block model is created from information obtained from exploration drilling. For the iron ore mine, the initial exploration drilling was done on a 100 m × 100 m grid in order to cover the major outcrop. The orebody was found to be complex; therefore, the 100 m × 100 m grid was then reduced to a 50 m × 50 m grid in order to obtain sufficient ...
