Iron ore extraction techniques - ScienceDirect

01/01/2015  Iron ore was won by drilling and blasting ().As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as “dogger”) allowing mine drivages to be self-supporting. However, he states that in later years where the mining

Chapter 8 BLAST DESIGN - National Park Service

Delay patterns, and varying the hole array to fit natural excavation topography, allow for more efficient use of the explosive energy in the blast. Benches may be designed and carried forth with more than one face so that simple blasting patterns can be used to remove the rock.

Mining of Iron Ores – IspatGuru

14/03/2014  Drilling in the benches of open pit mining is done for production of iron ore with mechanized drills specific for each mining method. The main objective of drilling operations is to create a hole of suitable diameter, depth and direction in rock for explosives to be placed for blasting activities. The drilling of the holes is done normally in a particular pattern which

Drilling and Blasting Technical Aspects of Mining ...

Mining explosives are substances which detonate to produce a high-intensity shock wave and large volumes of gas which, being confined in a hole, expand rapidly, entering existing minor cracks in the rock, and creating new cracks to break the rock. Explosives used to break rock are collectively called fracture explosives. This distinguishes them from accessories which are,

Different Types of Explosives Used in Mining

04/09/2019  In other words, are we using the same explosives in mining and warfare? Well, yes and no. From the ninth century AD (though the historians are still uncertain about the exact date of its invention) to the mid-1800s, black powder was the only explosive available. A single type of explosives was therefore used as a propellant for guns and for blasting purpose in any military, mining and civil ...
