How Mine Blasting takes place in an Iron Ore Mine Mine

31/08/2016 This was one of my nice experiences to witness blasting operation in an open cast iron ore mine (somewhere in India). I thought I would share this video on Y...

Optimization of Blasting Parameters in opencast Mines

efforts to introduce mechanization in the opencast mines, blasting continue to dominate the production. Explosives contribute currently about 5% of the direct cost of production and if the aggregate cost of drilling and blasting is taken together, this may go as high as 30% of direct cost of production. Therefore to cut down the cost of production optimal fragmentation from properly

01/01/2015 Extraction operation of iron ore in the studied mines are done by opencast mining. Extraction stages include drilling operations, blasting, loading and hauling . Hole drilling is done by rotary and percussion machinery in different diameter (165, 200 and 251 mm). In these mines, blast holes are controlled in ANFO (in dry conditions) and Emulite (for aqueous conditions) as the main

Iron Ore Orica

Advanced blasting technology can improve the flexibility of your drilling capacity and reduce cost without compromising results or productivity. The flexibility to fire bigger blasts is invaluable to mine scheduling as it results in fewer disruptions to the mining operation, avoiding loss of production.

Understanding Iron Ores and Mining of Iron Ore IspatGuru

The wide holes in the ground created by drilling, blasting, and ore removal are referred to as ‘open pits’. Following blasting, the fractured ore is known as run of mine (ROM) ore. ROM ore is loaded by huge electrical shovels, hydraulic excavators, or front-end loaders onto large capacity dump trucks, which haul it to crushing and screening station. Crushing and screening. Iron ore of

Drilling and Blasting Technical Aspects of Mining

Most blasting in mines involves charging explosives into holes drilled in rock. The entrance or mouth of a drill hole is called the collar and the end is the toe. Drilling is still carried out in some cases, in the ASM sector, by hand, using a hammer and chisel. This is obviously tedious and slow, especially in hard-rock mining conditions. Hand-drilled holes seldom exceed 400mm in length. Most

Mining of Iron Ores IspatGuru

Large iron ore mines are mechanized mines while manual mining methods are employed in the small mines. Manual mining method is normally limited to float ores. Mining of reef ore is also being done manually on a small scale. The float ore area is dug up manually with picks, crow bars, and spades, and then the material is manually screened to separate + 10 mm float ore which is then stacked up
