Mining Iron Ore Mining iron ore begins at ground level. Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth. Taconite rock comprises about 28 percent iron; the rest is sand or silica. These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan.

mining in fresh volcanics and banded iron formations. For maximum profitability the development of the pit requires strict wall control blasting techniques to ensure the walls are both safe and cut to design angle. Presplitting is carried out in both transitional (Fig 2) and fresh rock (Fig 4), with trim blasting .
As the higher the drill angle the more the cast is, it is recommended to increase the drilling angle to 20 degrees. Larger diameter (229mm) is better suited for cast blasting for improved cast and cost. Cost analysis showed that designs with larger diameter blast holes lead to reduced mining cost and faster coal uncovery rate.
Blasting, process of reducing a solid body, such as rock, to fragments by using an blasting operations include (1) drilling holes, (2) placing a charge and detonator in each hole, (3) detonating the charge, and (4) clearing away the broken material.
