Blasting is believed to be one of the most important operations in mining extraction. One of the main parameters which has to be considered in blasting is rock mass quality. Dynamic strengths of rocks, their spacing and orientation of joints planes and cracks as well as lithology and thickness of bedding are thought to be the most influential factors in blast design.
Wall Control Blasting Practices at BHP Billiton Iron Ore.

Using Low Density Explosives In Iron Ore Applications REDUCING THE OVERALL COST OF BLASTING AT IRON ORE MINES Dyno Nobel developed BlastLite® and TITAN® as cost effective solutions for blasting weak to medium strength rock in Iron Ore mines. The key to BlastLite lies in its ability to form a homogeneous
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. It improves productivity through:

Most iron ores occur in mine benches as complex mixtures of lithologies and ore types. This significantly complicates their characterisation for both blast design and fragmentation modelling. A great deal of technical and research effort has been applied to the development of models to predict fragmentation from rock blasting. A number of quite useful engineering models are currently available ...
A blast furnace is a special type of furnace for smelting iron from ore.Blast furnaces are very large. They can be up to 60 metres (200 ft) tall and 15 metres (49 ft) in diameter.The blast furnace is the biggest chemical reactor.Blast furnaces are also called high ovens..
