Mining of Iron Ores – IspatGuru
Mar 14, 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 activitiesDec 10, 2016 The mining industry is continually looking for new drilling solutions that enable them to mine iron ore mine in Sweden ; Thank drilling is proving its worth iron ore drilling process 芦 Drilling and blasting iron ore mine YouTubeDec 13, 2018 It is the most common drilling technique used for mining exploration, particularly in South America and Australia RC drilling is a form of percussion drilling, by which the rock is made to fail through the use of a piston that delivers rapid impacts to the drill stem, transferring energy to the drill Drilling Techniques for Mining Exploration Equipment
Drilling and Blasting Technical Aspects of Mining
Drilling 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 chiseltype of drilling is bedrock diamond core drilling, but other methods, like sonic drilling, are also used, depending on sampling goals The drilling process is a common practice in mineral exploration to obtain subsurface samples The land use for drilling is a temporary activity that is highly regulated, and the land is reclaimed after drillingEXPLORATION DRILLING BEST MANAGEMENT PRACTICESJan 01, 2015 Iron ore was won by drilling and blasting (Figure 71) 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 selfsupportingIron ore extraction techniques ScienceDirect
