Recently developed blasting techniques in frozen iron ore at .
Since 1956 IOC has been blasting frozen iron ore first in the Ferriman-Gagnon area during the period 1956 to 1964 and since 1970 in the Fleming-Timmins area Farnam 1961 ; Lang 1966 . The main problems encountered in connection with blasting in perma- frost were first caving in of drill holes due to melting of ice during drilling.

Drilling and blasting - Wikipedia
Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics to break rock for excavation.It is practiced most often in mining quarrying and civil engineering such as dam tunnel or road construction.
Iron Ore - Orica
Maintaining the integrity of walls is essential to the safe operation and maximise recovery of iron ore deposits. Orica’s range of solutions for wall control blasting enables steeper walls and faster vertical advance in cutbacks; reducing the stripping ratio bringing forward revenue and increasing the project NPV.

Wheelblasting Machines and Equipment Wheelabrator
Process-safe shock and impact-free blast cleaning of single rotation-symmetric parts is easily achieved on a Horizontal Belt shot blast system. These machines ensure consistent and uniform exposure of the workpiece under the blast stream and are ideal for high quality blasting of lighter parts that would be damaged in a tumblast system.
H BLASTING IN SURFACE EXCAVATION
Example: A new iron ore deposit is to be worked by surface mining methods with 15 m benches using 150 mm diameter blastholes. Since the prevailing condition is dry rock it has been decided to use bulk ANFO with emulsion cartridges as primer.
