Drilling And Blasting Of Iron Ore. Roughly 98 of iron ore on the global market is used in iron and steel production.Mining and processing.Common methods of extracting the iron ore consist of blasting, drilling, or general excavating,,.Most iron ore is produced from open-pit mines.After the iron ore is out of the ground, it may be shipped to the iron and steel manufacturing.

Jan 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 had progressed to the dip, this
Kiruna Iron Ore Mine Mining Technology. With an ore body 4km long 80m thick and reaching a depth of 2km LKAB s Kiruna is the world s largest most modern underground iron ore mine. In virtually all forms of mining rock is broken by drilling and blasting the rock. Blasting technology is the .
blasting methods in iron ore mines in india. 2012-7-5 · Drilling and blasting are the major unit operations in opencast mining. Inspite of the best efforts to introduce mechanization in the opencast mines, blasting continue to dominate the production.
1. Drilling and blasting. By far the bulk of rock excavated in mining globally is broken by drilling and blasting. Mining is the largest consumer of civil explosives. 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
ore on electricity; an equivalent amount on grinding media in the SAG circuit alone; but only $0.30/t of broken ore on explosives at the drill and blast stage. Yet, the blasting process is a much more energy efficient method of fragmenting rock. The need for energy efficient processing is becoming increasingly important as we continue
Mar 22, 2019 Traditionally blast hole drilling had no way to gather real-time data. Now not only are mine operators receiving information while the blast drill boars the holes but they are receiving high resolution imaging giving them a complete picture of the ore body leading to more efficient and accurate decision making.
