CIVIL ENGINEERING – Vol. II - Drilling Machines - H.Watanabe ©Encyclopedia of Life Support Systems (EOLSS) Figure 3: Typical drilling applications a) underground mining and tunneling, b) quarrying, c) strip mining For large-scale open pit mining, it is common to use rotary drilling rigs equipped with three-cone bits or DTHs to drill blastholes.
This stockpile of iron ore pellets will be used in steel production. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe
