History
The First Open Pit Mining Site – The Jackson Mine. Discovering iron ore was easier than mining it. This first open pit mine in the Lake Superior region started as a mountain of ore 150 feet high. Workers began prying ore from the surface with a bar and pick. Later they hand- drilled holes and filled them with explosives to fracture the ore body.

The easiest way to mine the valuable ore bodies is through the use of explosives and w ell-planned blasting layouts which can produce good fragm entation profiles.
Estimation of Optimum Burden for Blasting of Different …
Two different approaches have been used in this paper for computation of optimal burden of different rock strata of an Indian iron ore mine. The first approach is based on assessment of rock mass properties and explosive properties for the blast. The assessed properties are put in different empirical equations of Kuz-Ram model.
Iron ore mining and dressing
These countries account for around 85 % of the total global iron ore mining volume. Ore deposits are natural accumulations of ores that can be mined economically! The iron ore extracted in the deposits, mostly by blasting, is initially very coarse and unwieldy, which gives this untreated rock the name coarse ore.
